PHP XML Reader

XMLReader Open

You can either open an XML file with

XMLReader::open($xmlfile)

or set the xml directly with

XMLReader::xml($xml)

XMLReader Example

$xmlread = new XMLReader();

$xmlread->xml($xmlresp);

$xmlread->read();   // read /Root

$xmlread->read();   // read first element /Element

while (true) {      // loop through all elements at this level

  echo $xmlread->name.' '.$xmlread->nodeType.PHP_EOL;

  if (!$xmlread->next()) break;

}

exit;

Copy XMLReader node into a DOMDocument

Once you've got an XML Reader node you can convert it into a DOM Document node by using expand, importNode and appendChild

$rnode = $reader->expand();

$dom = new DOMDocument();

$dnode = $dom->importNode($rnode,true); // recursively = true

$dom->appendChild($dnode);      // append childnode to DOM Document root node
