PHP Xpath- Select element out of another element

Question

I have problem with Xpath function in PHP. I have created simpleXML than ran xpath to it. Then I wanted to run it to the result of the xpath but only apply it to first element. But it still taking all elements like there was no xpath used. I also printed how the array looked after first xpath and it took exacly what I wanted. Can anyone help, please?

$elem = simplexml_load_file($fileIn);

$xpathArg = "//".$arg['eFR'];
$prem = $elem->xpath($xpathArg);

$xpathArg2 = "//".$arg['eSE'];
print_r($prem[0]->xpath($xpathArg2));

please post a valid mini snippet of the XML in question. And what you want it to be. And what you got instead. And content of $arg[] - a complete, self-containing code example. Professional question = professional answers. — michi

An XPath starting with / is an absolute path. You want a path starting from the context node, otherwise the context node is ignored. Simply prepending a . at the beginning of your second xpath query will ensure it starts from the node you specify.

$elem = simplexml_load_file($fileIn);

$xpathArg = "//".$arg['eFR'];
$prem = $elem->xpath($xpathArg);

$xpathArg2 = ".//".$arg['eSE'];
print_r($prem[0]->xpath($xpathArg2));
