for example we have this xml:
<body>
<a>
<b>
<c>hello</c>
<c>world</c>
</b>
</a>
<a>
<b>
<c>another hello</c>
<c>world</c>
</b>
</a>
</body>
by Xpath query we can find all "B"-tags. But then we need to find all "C"-tags in every found "B"-tag. I wrote this code:
$dom = new DOMDocument();
$dom->loadXML($xml);
$xpath = new DOMXPath($dom);
$btags = $xpath->query("//b");
foreach ($btags as $b)
{
$ctags = $xpath->query("/b/c", $b);
foreach ($ctags as $c) {
echo $c->nodeValue;
}
}
But it doesn't work. It possible to do this with XPath query's?
