DOMText::splitText
When using DOMXPath and having a default namespace. Consider using an intermediate function to add the default namespace to all queries:
<?php
// The default namespace: x:xmlns="http://..."
$path="/Book/Title";
$path=preg_replace("\/([a-zA-Z])","/x:$1",$path);
// Result: /x:Book/x:Title
?>

For more then one search this function will be helpfull:
<?php
class xpathExtension{
public static function getNodes($domDoc, $xpathString) {
$xp = new DOMXPath($domDoc);
$xp->registerNamespace('x', 'http://www.w3.org/1999/xhtml');
$xp->registerNamespace('xhtml', 'http://www.w3.org/1999/xhtml');
$xp->registerNamespace('i18n', 'http://apache.org/cocoon/i18n/2.1');
$ret = array();
$nodes = $xp->query($xpathString);
foreach ($nodes as $node) {
array_push($ret, $node);
}
return $ret;
}
}
$domDoc = new DOMDocument();
$domDoc->load("xmlFile.xml");
$xpathString = "//html/body/*[@class='text']";
$domNodeList = xpathExtension::getNodes($domDoc, $xpathString);
foreach($domNodeList as $domNode){
echo $domNode->nodeName;
}
?>
