PHP Curl检测错误的xml

Question

I have been experiencing some bad returns on xml that I get from another server. I'd like to add some reporting on this for myself but I need to find a sure fire way to identify when simple xml fails.

The errors happen on this specific point $xmlResponse = new SimpleXMLElement( $response );

so basically if there is SimpleXMLElement->__construct error trigger i want to detect this and fire my reporting.

E.g.

if($xmlResponse === Fail){
 // Do reporting
}

any ideas appreciated. I also cant rely on http responses as the response code could be fine but there might be issues with the xml itself.

Answer 1

if you just want to check if the xml is malformed,

if(!(@DOMDocument::loadXML($xml))){
  // do reporting
}

• funfact: pretty much the only difference between DOMDocument's loadXML and loadHTML is that loadHTML accepts malformed xml, while loadXML does not.
