Looks like a trivial question, but in order 'to determine the location of a particular XML element in XML document' all that is needed and used is an XPath expression. An XPointer is simply an XPath expression, often a location path, enclosed in the parentheses of xpointer(). However, An XPointer can identify points and ranges, which are two new nodes types. So, I would also answer XPath and XPointer but it's a close call :roll: Cheers, Dan
