key Function (Windows Embedded CE 6.0)
1/6/2010
Retrieves elements previously marked with an xsl:key statement.
Syntax
node-set key(name, value)
Parameters
- name
Element name.
- value
Key value.
Return Value
Elements previously marked with xsl:key which match the name and value specified in the arguments.
Remarks
The key() function retrieves a node set (zero or more nodes) that have the same key name and key value specified in the <xsl:key> statement. When the XSL Transformations (XSLT) style sheet is first processed, the keys are stored internally to simplify access. Keys can simplify accessing nodes in the XML document, but may not be faster than using XML Path Language (XPath) to retrieve the same nodes.
