Selects a single node from a collection matching an XPath expression. This method differs from the CustomXMLPart.SelectSingleNode method in that the XPath expression will be evaluated starting with the 'expression' node as the context node.

Note
References to DTDs from custom XML parts are not supported. DTD references in custom XML parts will not resolve, and custom XML parts containing DTD references generate an exception when an attempt is made to save the file's content to a flat XML file.

Syntax

expression.SelectSingleNode(XPath)

expression An expression that returns a CustomXMLNode object.

Parameters

Name Required/Optional Data Type Description
XPath Required String Contains an XPath expression.

Return Value
CustomXMLNode

Remarks

The prefix mappings for the XPath expression are retrieved from the NamespaceManager property.

Example
The following example demonstrates adding a custom XML part, selecting a part with a namespace URI, and then selecting a node within that part that matches an XPath expression.

Visual Basic for Applications 
Dim cxp1 As CustomXMLPart Dim cxn As CustomXMLNode ' Add a custom xml part. ActiveDocument.CustomXMLParts.Add "<supplier>" ' Return the first custom xml part with the given namespace. Set cxp1 = ActiveDocument.CustomXMLParts("urn:invoice:namespace") ' Get a node using XPath. Set cxn = cxp1(1).SelectSingleNode("//*[@supplierID = 1]")
