If the query() function seems to ignore your $contextnode, and instead returns all the tags in the
document, try to use a relative path (use a . in front of the query):
<?php
$xml = "<?xml version='1.0' encoding='UTF-8'?>
<test>
<tag1>
<uselesstag>
<tag2>test</tag2>
</uselesstag>
</tag1>
<tag2>test2</tag2>
</test>";
$dom = new DomDocument();
$dom->loadXML($xml);
$xpath = new DomXPath($dom);
$tag1 = $dom->getElementsByTagName("tag1")->item(0);
echo $xpath->query("//tag2")->length; //output 2 -> correct
echo $xpath->query("//tag2", $tag1);->length; //output 2 -> wrong, the query is
not relative
echo $xpath->query(".//tag2", $tag1);->length; //output 1 -> correct (note the
dot in front of //)
?>
I thought PHP would do this for me, but it doesn't.
