Current Version: 11.5.0
Chilkat.Xml
Load XML from strings, files, byte data, or other Chilkat objects, then
save or emit formatted XML when processing is complete.
Move through parent, child, sibling, and selected elements while working
directly with the XML document structure.
Add, update, remove, or rename elements; set text content; and read,
add, modify, or delete attributes.
Locate elements by tag name, content, path, attribute value, or custom
search patterns.
Work with namespace-aware XML, declarations, CDATA, child ordering,
sorting, and subtree insertion or removal.
Store binary data as Base64 and optionally compress or encrypt element
content when XML carries encoded payloads.
For an extended overview, see
Xml Class Overview.
Load, navigate, search, edit, transform, and save in-memory XML trees.
Chilkat.Xml is the primary Chilkat class for in-memory XML tree
manipulation. It supports loading and saving XML, navigating between elements,
reading and writing text content, managing attributes, working with
namespaces, adding and removing subtrees, searching by tag, content, or
attribute, sorting child records, scrubbing XML, handling CDATA and XML
declarations, storing binary data as Base64, and optionally compressing or
encrypting element content.
Load and save XML
Navigate XML trees
Edit elements and attributes
Search and select
Namespaces and structure
Binary and protected content
Xml object reference for the selected
element, while methods ending in 2 update the caller's internal
reference to point to a different element. This distinction is central when
navigating and editing XML trees because it determines whether the current
object stays where it is or moves to another element.
Chilkat.Xml for tree-oriented XML
manipulation, and use Chilkat.XmlDSig,
Chilkat.XmlDSigGen, or related classes when the task is XML
digital signing or signature verification.
Object Creation
Note: For a specific major version, use "Chilkat.Xml.<major_version>", such as "Chilkat.Xml.10" for Chilkat v10.*.* See Chilkat ActiveX Object Creation (ASP) set obj = Server.CreateObject("Chilkat.Xml") (AutoIt) $obj = ObjCreate("Chilkat.Xml") (Visual Basic 6.0) Dim obj As New ChilkatXml (VBScript) set obj = CreateObject("Chilkat.Xml") (VBA, such as Excel) Dim obj As New ChilkatXml See How to Use ActiveX in Excel (Delphi) obj := TChilkatXml.Create(Self); (FoxPro) loObject = CreateObject('Chilkat.Xml') (PowerBuilder) lole_object = create oleobject li_rc = lole_object.ConnectToNewObject("Chilkat.Xml") (SQL Server) EXEC @hr = sp_OACreate 'Chilkat.Xml', @obj OUT (Javascript) var obj = new ActiveXObject("Chilkat.Xml");
Properties
Cdata
Controls how this element's text content is emitted. When set to 1, the element content is written inside a CDATA section instead of being emitted as ordinary character data with XML escaping.
< or &. It does not change the logical text value of the element; it only changes how that text is represented in the serialized XML.Content
Gets or sets the text content stored directly on this XML element. Child elements are not included in this value.
For example, both of the following elements have This is the content as their Content:
<tag1>This is the content</tag1> <tag2><child1>abc</child1><child2>abc</child2>This is the content</tag2>
ContentInt
Gets or sets this element's content as a 32-bit integer. Setting the property converts the integer to its decimal text representation; getting the property interprets the element's text content as an integer.
Content when the value may exceed the range of a 32-bit integer or when the exact lexical representation must be preserved.DebugLogFilePath
If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.
Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.
Possible causes of hangs include:
- A timeout property set to 0, indicating an infinite timeout.
- A hang occurring within an event callback in the application code.
- An internal bug in the Chilkat code causing the hang.
DocType
Gets or sets the document type declaration associated with the XML document.
The value represents the document-level DOCTYPE declaration, for example <!DOCTYPE note SYSTEM "note.dtd">.
EmitBom
Controls whether a byte order mark (BOM, also called a preamble) is written when XML is saved to a file. The default is 0.
This setting is relevant to encodings for which a BOM can be emitted, such as UTF-8 and UTF-16. It does not affect XML returned as a language string by methods such as GetXml.
EmitCompact
Controls whether XML emitted by GetXml and GetXmlSb is compact. When 1, unnecessary formatting whitespace and line breaks are omitted. The default is 0 for backward compatibility.
EmitXmlDecl
Controls whether the XML declaration is included when XML is emitted. The default is 1. When set to 0, output methods such as GetXml and SaveXml omit the declaration.
An XML declaration is the leading construct such as <?xml version="1.0" encoding="utf-8"?>.
Encoding
Gets or sets the encoding value used in the XML declaration. The default is utf-8. This is a document-level setting and may be accessed from any element in the tree.
When XML is loaded, Chilkat sets this property from the encoding declared by the input XML when one is present. If no encoding is declared, the property is reset to utf-8.
Encoding changes the declared/output encoding used when XML is serialized; it does not reinterpret or transcode the already-stored Unicode text inside the in-memory tree.I
Provides a substitution value for [i] in Chilkat tag paths and ChilkatPath expressions. When a path contains [i], the current value of this property is substituted for I.
I, J, and K properties make it convenient to reuse a path expression inside nested loops without constructing a new path string for every index.IsBase64
Returns 1 if this element's content consists only of characters allowed in standard Base64 text, with whitespace ignored. Standard Base64 uses A-Z, a-z, 0-9, +, /, and optional trailing = padding.
J
Provides a substitution value for [j] in Chilkat tag paths and ChilkatPath expressions. When a path contains [j], the current value of this property is substituted for J.
I, J, and K properties make it convenient to reuse a path expression inside nested loops without constructing a new path string for every index.K
Provides a substitution value for [k] in Chilkat tag paths and ChilkatPath expressions. When a path contains [k], the current value of this property is substituted for K.
I, J, and K properties make it convenient to reuse a path expression inside nested loops without constructing a new path string for every index.LastBinaryResult
This property is mainly used in SQL Server stored procedures to retrieve binary data from the last method call that returned binary data. It is only accessible if Chilkat.Global.KeepBinaryResult is set to 1. This feature allows for the retrieval of large varbinary results in an SQL Server environment, which has restrictions on returning large data via method calls, though temp tables can handle binary properties.
LastErrorHtml
Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastErrorText
Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
LastErrorXml
Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastMethodSuccess
Indicates the success or failure of the most recent method call: 1 means success, 0 means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages. Note: This property does not apply to methods that return integer values or to boolean-returning methods where the boolean does not indicate success or failure.
LastStringResult
In SQL Server stored procedures, this property holds the string return value of the most recent method call that returns a string. It is accessible only when Chilkat.Global.KeepStringResult is set to TRUE. SQL Server has limitations on string lengths returned from methods and properties, but temp tables can be used to access large strings.
LastStringResultLen
The length, in characters, of the string contained in the LastStringResult property.
topNumAttributes
Returns the number of attributes on this element.
For example, <tag attr1="value1" attr2="value2">...</tag> has two attributes. Attribute indexes used by methods such as GetAttributeName and GetAttributeValue are zero-based.
NumChildren
Returns the number of direct child elements of this element. Descendants below those children are not included in the count.
SortCaseInsensitive
Controls case sensitivity for the XML sorting methods. Set to 1 for case-insensitive string comparisons or 0 for case-sensitive comparisons.
Standalone
Controls the standalone pseudo-attribute in the XML declaration. This is a document-level setting and may be accessed from any element in the tree.
Setting this property to 1 causes the declaration to include standalone="yes".
Tag
Gets or sets the element name for this element, including any namespace prefix. For example, the tag for <soapenv:Body> is soapenv:Body.
Use TagNsPrefix and TagUnprefixed when the prefix and local portion are needed separately.
TagNsPrefix
Gets or sets the namespace prefix portion of this element's tag. For soapenv:Envelope, the namespace prefix is soapenv.
xmlns attributes in the XML.TagPath
Returns the Chilkat tag path needed to reach this element from the document root. If this object currently references the root element, the returned path is the empty string.
| between element names. It is not an XPath expression.TagUnprefixed
Gets or sets the unprefixed portion of this element's tag. For soapenv:Envelope, the unprefixed tag is Envelope.
Use TagNsPrefix to access the prefix separately.
TreeId
Returns the identifier of the XML tree to which this element belongs. Elements in the same XML document have the same TreeId.
Xml objects can reference different elements in the same underlying tree. Comparing TreeId values is a convenient way to determine whether two element references belong to that same tree.UncommonOptions
Provides a catch-all string for uncommon XML behaviors. The default is the empty string, which is appropriate for normal use.
Leave this property empty unless Chilkat documentation or support identifies a specific option needed for a specialized interoperability case.
topVerboseLogging
If set to 1, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is 0. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.
Version
Version of the component/library, such as "10.1.0"
Methods
AccumulateTagContent
Traverses the subtree rooted at the calling element and concatenates the text content of all elements whose tag equals tag.
skipTags is a vertical-bar-delimited list of tag names whose entire subtrees are excluded from the accumulation. For example, script|style skips elements rooted at either of those tags.
Returns Nothing on failure
AddAttribute
Adds an attribute named name with the specified string value to the calling element.
Returns 1 on success and 0 on failure.

Returns 1 on success and 0 on failure.
Returns 1 for success, 0 for failure.
topAddChildTree
Adds the entire XML subtree referenced by tree as a new direct child of the calling element.
If tree already belongs to another XML document, the subtree is transferred to the destination tree rather than copied as an unrelated duplicate.
TreeId can be used to determine which tree an element reference belongs to.Returns 1 for success, 0 for failure.
AddOrUpdateAttribute
Sets the string value of an attribute on the calling element. If an attribute named name already exists, its value is replaced; otherwise the attribute is added.
AddOrUpdateAttributeI
Sets an integer-valued attribute on the calling element. If an attribute named name already exists, its value is replaced with the decimal representation of value; otherwise the attribute is added.
AddStyleSheet
Adds an XML stylesheet processing instruction to the document. Pass the complete processing-instruction text, for example:
<?xml-stylesheet href="mystyle.css" title="Compact" type="text/css"?>
AddToAttribute
Treats the named attribute value as an integer, adds amount, and stores the resulting integer back in the attribute.
If the attribute does not yet exist, this method behaves like AddOrUpdateAttributeI and creates it with amount as the value.
AddToChildContent
Finds the child identified by tag, interprets its content as an integer, adds amount, and stores the resulting integer as the child's new content.
AddToContent
Interprets this element's content as an integer, adds amount, and stores the resulting integer as the new content.
AppendToContent
Appends str to the existing text content of the calling element without replacing its child elements.
Returns 1 on success and 0 on failure.
Returns 1 for success, 0 for failure.
topBEncodeContent
Sets this element's content to an RFC 2047-style encoded-word using Base64 (the B encoding). inData contains bytes in the character encoding named by charset.
For example, using Big5 can produce content similar to =?Big5?B?pHCtsw==?=. The encoded payload is Base64 text inside the encoded-word syntax.
Use DecodeContent to recover the encoded bytes.
Returns 1 for success, 0 for failure.
topChildContentMatches
Returns 1 if the child identified by tagPath has content matching pattern; otherwise returns 0. caseSensitive controls whether letter case is significant.
The pattern may contain * wildcards, where each asterisk matches zero or more characters.
|-separated child-navigation syntax, for example tagA|tagB|tagC. It is not XPath.ChilkatPath
Evaluates a Chilkat-specific path command that can navigate from the current element, return element content or an attribute value, or move the caller's internal element reference.
This syntax is not XPath. Commands are separated by vertical bars and the expression ends with a return command:
command|command|command|...|returnCommand
Navigation commands include:
TagName— first direct child having that tag.TagName[n]— the indexed direct child having that tag...— parent.++/--— next / previous sibling.TagName{Content}— first direct child with that tag and exact content./T/TagName— traverse the subtree and find the first element with that tag./C/TagName,ContentPattern— traverse for a tag whose content matches a wildcard pattern./C/ContentPattern— traverse for any tag whose content matches a wildcard pattern./A/TagName,AttrName,AttrValuePattern— traverse for a tag having a matching attribute value.
The final return command is:
*— return the current element's content.(AttrName)— return an attribute value.$— move thisXmlobject to the selected element and return an empty string.
I, J, and K properties can be used with [i], [j], and [k] in path expressions.Returns Nothing on failure
Clear
Clears the calling element by removing all child elements, attributes, and text content, and resets its tag name to unnamed.
The element itself remains in the tree; this method clears its contents rather than removing the element from its parent.
topContentMatches
Returns 1 if this element's content matches pattern; otherwise returns 0. caseSensitive controls whether letter case is significant.
The pattern may contain * wildcards, where each asterisk matches zero or more characters.
Copy
Copies the Tag, Content, and attributes from node to the calling element.
AddChildTree or SwapTree when child structure is part of the operation.CopyRef
Changes this Xml object so that it references the same underlying XML element as copyFromNode. The caller's previous element reference is discarded.
CopyRef does not copy XML data. After the call, both Xml objects refer to the same element, so edits through either reference affect the same tree element.DecodeContent
Decodes this element's RFC 2047-style Q- or B-encoded content and returns the decoded bytes.
This is the inverse of QEncodeContent and BEncodeContent.
Returns a zero-length byte array (as a Variant) on failure.
An empty array will have a UBound of -1 meaning 0 elements.
DecodeEntities
Decodes HTML character entities found in str and returns the decoded text. This is a utility operation; it does not modify the XML tree unless the returned string is assigned to an element.
For example, an HTML entity such as & is decoded to &.
Returns Nothing on failure

EncryptContent. It is not a general XML Encryption (XML-Enc) implementation.Returns 1 for success, 0 for failure.
EncryptContent
Encrypts the calling element's text content using Chilkat's password-based 128-bit AES-CBC format and replaces the plaintext content with Base64-encoded encrypted data.
Returns 1 on success and 0 on failure.
DecryptContent with the same password to restore the content.Returns 1 for success, 0 for failure.
ExtractChildByIndex

RemoveChildByIndex, extraction gives the caller a reference to the removed subtree so it can be retained, inspected, or attached elsewhere.Returns Nothing on failure
ExtractChildByName
Finds, removes, and returns the first child selected by tagPath and the optional attribute criteria.
If attrName and attrValue are empty, the first child matching the tag/path is extracted. If attrName is provided, the child must have that attribute. If attrValue is also provided, the attribute value must match exactly.
