text Property

  • 项目

Represents the text content of the node or the concatenated text representing the node and its descendants.

strValue = oXMLDOMNode.text;

HRESULT get_text(
  BSTR* text
);

General Remarks

When concatenated, the text represents the contents of text or CDATA nodes. All concatenated text nodes are normalized according to xml:space attributes and the value of the preserveWhiteSpace switch. Concatenated CDATA text is not normalized. (Child nodes that contain NODE_COMMENT and NODE_PROCESSING_INSTRUCTION nodes are not concatenated.)

Retrieves and sets the string representing the text contents of this node or the concatenated text representing this node and its descendants.

For more precise control over text manipulation in an XML document, use the lower-level nodeValue property, which returns the raw text associated with a NODE_TEXT node.

Consider the "root" element in this example.

<root att="   123   a   <   ">
   <a>   a   a   </a>
   <!--   comment   b   -->
   <?pi   pi   c   ?>
   <![CDATA[   cdata   d   ]]>
   e   f
</root>

The text property for the root element returns the following concatenated text.

"a a   cdata   d    e f"

Note that the white space within the CDATA node is preserved.

This value depends on the value of the nodeType property.

Value Description
NODE_ATTRIBUTE, NODE_DOCUMENT, NODE_ENTITY Returns a string representing the value of the node. This is the concatenated text of all subnodes with entities expanded.
NODE_CDATA_SECTION, NODE_COMMENT, NODE_PROCESSING_INSTRUCTION, NODE_TEXT Returns the text contained in the node, which is the same as the nodeValue property.
NODE_DOCUMENT_TYPE, NODE_NOTATION Returns the empty string (""). These node types do not have associated text.
NODE_DOCUMENT_FRAGMENT Returns the text comprised of the concatenation of all descendant nodes.
NODE_ELEMENT Contains a string that represents the element content. Note that this will also include the text content from all child elements, concatenated in document order. For example, consider the following XML: 
<count>
  <item>one</item>
  <item>two</item>
  <item>three</item>
  <item>four</item>
</count>

The text property for the <count> element contains the value "one two three four".
NODE_ENTITY_REFERENCE Returns the string representation of the entity reference.

This property is read/write, and applies to the following objects and interfaces:

IXMLDOMAttribute, IXMLDOMCDATASection, IXMLDOMCharacterData, IXMLDOMComment, DOMDocument, IXMLDOMDocumentFragment, IXMLDOMDocumentType, IXMLDOMElement, IXMLDOMEntity, IXMLDOMEntityReference, IXMLDOMNode, IXMLDOMNotation, IXMLDOMProcessingInstruction, IXMLDOMText, and IXTLRuntime.
