i'am testing an xml structure:
<Articles> ... <Article ID="333"> <author>Paul</author> <title>i hate xpath </title> <child1>bla</child1> <child2>blabla <subchild> <subsubchild DEEP = "Attribute"></subsubchild> //this is the value i wanna update and my nightmare </subchild> </child2> <child3>testing</child3> </Article> ... </Articles>
what xpath expression will fetch and update (change) the subsubchild attrib node value ? i am mostly concerned with fetching and updating sub values of any node, no matter how deeply or superficially located, if the parent ID (333 in this case). is known ? currently i have used :
$query= "//*[@ID=333]//*node()[@DEEP and @DEEP = "Attribute"]"; $outcome = $xml->xpath($query); echo isset($outcome) ? "found" : "unavailable";
and several more related xpressions, they're all fraustrating my efforts with "Invalid expression" error, reported as an output. can anyone be of help please ?
