Hi there,I am new to XML and XSL, so please bear with me if I ask simple questions.At the moment I have a problem to check availability of a worker in a list of workers.Here is the code:<Workers> <Worker id="1"> <name>John</name> </Worker> <Worker id="2"> <name>Smith</name> </Worker></Workers>I want to check if there is a worker called 'Jane' in the XML above by using XSL.<employees> <employee> <name>Jane</name> </employee></employees>And if Jane is not in the XML, I want to return a notification that Jane is not in the XML.How could I do this?Please help me.
