Interface XmlDocument

This interface describes methods and properties available to work with XML documents.
Conceptually, it is the root of the document tree, and provides the primary access to the document's data. The XmlNode objects created have a ownerDocument attribute which associates them with the XmlDocument within whose context they were created.

Methods

Return Type	Signature
XmlNode	CreateAttribute( string data)
XmlNode	CreateCDATASection( string data)
XmlNode	CreateComment( string data)
XmlNode	CreateElement( string tagname)
XmlNode	CreateElementNS( string namespaceURI, string qualifiedName)
XmlNode	CreateTextNode( string data)
string	GetXML( optional boolean preserve, optional boolean escape)
XmlNodeList	Query( string xpath)

Properties

Type	Property
XmlNode	documentelement

Methods

CreateAttribute

Creates an Attr of the given name. Note that the XmlNode instance can then be set on an XmlNode using the AppendChild method.
To create an attribute with a qualified name and namespace URI, use the CreateAttributeNS method.

XmlNode CreateAttribute(
string data)

Name	Description
data	The data for the node.

CreateCDATASection

Creates a CDATA node given the specified string.

XmlNode CreateCDATASection(
string data)

Name	Description
data	The data for the node.

CreateComment

Creates a Comment node given the specified string.

XmlNode CreateComment(
string data)

Name	Description
data	The data for the node.

CreateElement

Creates an element with the nodename tagname. Note that the instance returned implements the XmlNode interface, so attributes can be specified directly on the returned object.
To create an element with a qualified name and namespace URI, use the CreateElementNS method.

XmlNode CreateElement(
string tagname)

Name	Description
tagname	The name of the element type to instantiate. This is case-sensitive.

CreateElementNS

Creates an element with a namespace. Note that the instance returned implements the XmlNode interface, so attributes can be specified directly on the returned object.

XmlNode CreateElementNS(
string namespaceURI,
string qualifiedName)

Name	Description
namespaceURI	The namespace URI of the element to create.
qualifiedName	The qualified name of the element to instantiate.

CreateTextNode

Creates an XmlNode node given the specified string.

XmlNode CreateTextNode(
string data)

Name	Description
data	The data for the node.

GetXML

Returns the XML representation of the XmlDocument.
if preserve is true, the original XML is returned, otherwise the XML is normalized.

string GetXML(
optional boolean preserve,
optional boolean escape)

Name	Description
preserve	Keep whitespace structure.
escape	create a string that is XML escaped.

Query

Returns an XmlNodeList of all the XmlNodes matching a given XPath and contained in the document.

XmlNodeList Query(
string xpath)

Name	Description
xpath	The XPath which is evaluated to get the `XmlNode`s.

Properties

documentelement

The top XmlNode of the document.
