Hello there.

If we have a XML file like this :

Code:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<Information>
  <Data ID="0" X="?" Y="?" Z="?" />
  <Data ID="1" X="?" Y="?" Z="?" />
  <Data ID="2" X="?" Y="?" Z="?" />
  <Data ID="3" X="?" Y="?" Z="?" />
  <Data ID="4" X="?" Y="?" Z="?" />
  <Data ID="5" X="?" Y="?" Z="?" />
  <Data ID="6" X="?" Y="?" Z="?" />
  <Data ID="7" X="?" Y="?" Z="?" />
  <Data ID="8" X="?" Y="?" Z="?" />
  <Data ID="9" X="?" Y="?" Z="?" />
</Information>
How can we get this query :
The query : All nodes with the same X,Y,Z attributes.
e.g :
The query have to return something like this :

Code:
<Data ID="0" X="1" Y="2" Z="3" />
<Data ID="1" X="1" Y="2" Z="3" />
<Data ID="8" X="1" Y="2" Z="3" />
Thanks in advance
