It is not clear to me what you want to achieve. Do you want to find 
elements where the name matches a certain pattern? Or elements where the 
contents matches a certain pattern?

Also XPath 2.0 and XQuery 1.0 have regular expression support so you 
could do e.g.
   //*[matches(., 'someregularexpressionhere')]
to find all elements containing a string matching the regular expression 
provided in the second argument to the matches function.
