i have this xml and i trying to parse the values using xpath and exist db (in java). but the only one query which give me feedback is " //* ". I want to take the value of uri but i cant't. The //uri returns me null. I use eclipse tool about xpaths. It generate me the path but when i try that path in the same tools returns me again null. Any idea? thanks in advance...

Your XML has default namespace: http://www.w3.org/2005/sparql-results#. So you need to define it in your XML/XPath engine, define prefix (e.g. pr) and use it in XPath: //pr:uri. Or you can use this XPath:
//*[local-name() = 'uri'].
