Xslt Generate Id Key Example
Sep 22, 2009 Unique Values, XSLT/XPath 2.0. Unique values and grouping becomes much easier with xsl:for-each-group and current-grouping-key. Note we are now using a slightly more comprehensive version of conferences.xml. This is a thorny one. Functions in XSLT and XQuery can create new nodes, and this is a limited kind of side-effect. If f creates a new node, then f is f is defined to be false; similarly generate-id(f) = generate-id(f) will also be false. This means the optimizer has some work to do to decide whether functions have this effect or not. Returns the value of the first argument after outputting a diagnostic message. XPath 2.0 Specification. Note: The Saxon implementation outputs the value of each item in a sequence as it is evaluated (except when the sequence is empty, in which case it outputs 'empty sequence' at the start).Atomic values are output by converting them to a string, nodes by calling getPath to generate a path.
-->Xslt Generate Id Key Examples
Returns a string that uniquely identifies the node in the node-set argument that is first in document order.
Remarks
The unique identifier must consist of ASCII alphanumeric characters and must start with an alphabetic character. Thus, the string is syntactically an XML name. There is no guarantee that a generated unique identifier will be distinct from any unique IDs specified in the source document. If the node-set argument is empty, the empty string is returned. If the argument is omitted, it defaults to the context node.
Example
XML File (data.xml)
XSLT File (sample.xsl)
This is the formatted output:
When you click the left button in Internet Explorer, an alert box displays 'IDAHAGJD'.
When you click the right button in Internet Explorer, an alert box displays 'IDAPAGJD'.
Notice that the ID value is generate at run-time. Therefore, the specific values may vary in different invocation of the transformation.
