Generating Temporary IDs for Nodes

The generate-id() function, defined in the XSLT recommendation, generates temporary IDs for nodes.

Format

The format for the generate-id() function is as follows:

string generate-id(node-set?)
               

            

The generate-id() function returns a string that uniquely identifies the node in node-set that is first in document order. This string starts with xln and ends with eight hexadecimal digits. Syntactically, the string is an XML name.

If the node-set argument is empty, the generate-id() function returns an empty string. If you omit the node-set argument, the generate-id() function generates a temporary ID for the context node.
