either
//*[tag=3D'item2/3']

meaning fetch all nodes with a child element called tag whose content=20
=3D item2/3

or
//node[tag=3D'item2/3']

meaning: fetch all nodes called node with a child element called tag=20
whose content =3D item2/3

Check out phpxpath's testbench (testBench/useCases/index.php at=20
wherever you've installed the software) for working out xpath syntax.=20
The syntax is quite simple once you get the hang of it, but it is=20
confusing at first and the official w3c documentation doesn't contain=20
nearly enough examples.
