selectSingleNode Method (Compact 2013)

3/26/2014

Applies the specified pattern-matching operation to this node's context and returns the first matching node.


var objXMLDOMNode = oXMLDOMNode.selectSingleNode(queryString);
HRESULT selectSingleNode(
  BSTR queryString,
  IXMLDOMNode** resultNode
);

Script

queryString

String specifying the Extensible Stylesheet Language (XSL) or XPath query that is to be applied to the context defined by this node. The value of the SelectionLanguage internal property (flag) determines whether an XSL or XPath query is used. By default, the expression is an XSL pattern query. The SelectionLanguage internal property (flag) can be set with the setProperty methodxmmthsetProperty.

This method is only valid if the XML Query Language (XQL) feature has been included in the OS. If a call to this method is made and XQL is not supported, an error message will be returned.

The selectSingleNode method is similar to the selectNodes Method, but returns only the first matching node rather than the list of all matching nodes.
