ok sorry about the confusion I made. what I need to do is to generate a unique identifier for different nodes. so I need to generate an XML of the form below
<rule:foo rdf:ID="rule_N2320"> <rule:bar rdf:resource="constraint_N3456"/> </rule:foo>
<constraint:test rdf:ID="constraint_N3456"> <t1/> <t2/> <constraint:tes>
ok so as it is obvious in the code above, I need to generate two unique values, here "N2320" and "N3456", using a funciton and attach them to my terms, "rule" and "constraint".
I need to generate these two numbers at the same time in my xslt template as I need to keep track of the generated elements and their ids later in the code. I thought of generate-id() as the suitable function for my purpose. In one of the tutorials I read on XSLT it says that generate-id() can be used to generate a unique string for a node, so based on this single line hint, I thought that would be what I need but apparantly it isn't.
thanks in advance for the help, -Nima
generate-id() with no parameters is equivalent to generate-id(.) - it returns the identifier of the context node. If you call it twice with the same argument, it is guaranteed to return the same answer.
You seem to be in need of a completely different function, so you need to explain what you are trying to do.
