I wanted to find similar Elements - thats why I built an Xpath-String like this - maybe somebody
needs it... its not very pretty - but neither is domdocument :)
<?php
$dom->load($xmlFile))
$xpathQuery = '//*';
$xmlNodes = $xpath->query($xpathQuery);
$pathlist = array();
$attrlist = array();
foreach ($xmlNodes as $node) {
$depth = $this->_getDomDepth($node); //get Path-Depth (for array key)
$pathlist[$depth] = $node->tagName; // tagname
$attrs = $node->attributes;
$attr='';
$a=0;
foreach ($attrs as $attrName => $attrNode) // attributes
{
if ($attrName !='reg')
{
if ($a++!=0) $attr .= ' and ';
$attr .=
'@'.$attrName.'='."'".$attrNode->value."'";
}
}
$attrlist[$depth] = $attr?'['.$attr.']':'';
$path = ''; for ($i=0;$i<=$depth;$i++) $path .=
'/'.$pathlist[$i].$attrlist[$i]; // the xpath of the actual Element
// ... now you can go on and user $path to find similar elements
}
}
}
private function _getDomDepth(DomNode $node)
{
$r = -2;
while ($node) {
$r++;
$node = $node->parentNode;
}
return $r;
}
