Hi,

I've been tearing my hair out over this problem for hours (and I've precious little left as it is).  It's hopefully just a 'wood for the trees' moment.

I'm trying to parse XML search results using DOMDocument and DOMXPath, the problem is that the DOMDocument never seems to get populated.  I can load the XML result set via cURL fine, and the XML validates ok.  Here's my code:

$xmldoc = new DOMDocument(); 
$xmldoc->load( 'http://searchserver/xml.cgi?collection=test&query=' );

$xpath = new DOMXPath( $xmldoc ); 

$results = $xpath->query( "/padre_result_packet" ); 

echo '<pre>';
print_r( $results );
echo '</pre>';


And here's an example of the XML I'm working with:
Code: [Select]
<?xml version="1.0" encoding="iso-8859-1" standalone="no" ?>
<PADRE_result_packet>
<details>
<padre_version>Unknown</padre_version>
</details>
<error>
<usermsg>Please specify a valid query</usermsg>
<adminmsg>The query parameter is invalid or missing</adminmsg>
</error>
</PADRE_result_packet>

The result is:
Code: [Select]
DOMNodeList Object
(
)

Does anybody have some advice?  I was getting the following error when using $xmldoc->loadXML:
Code: [Select]
Warning: DOMDocument::loadXML(): Start tag expected, '<' not found in Entity, line: 1

Hello All,

 

I have searched these forums and the net but haven't found an exact answer.  I have a "path" (could be paths) that is/are causing warnings as it/they is/are poorly formed.  This is bloating our logs, therefore I need to alleviate the issue.

There are thousands of paths in the database so I do not know which are causing issues.

I know I can add the "@" to the call to quiet the warning.  First question: does that keep the warning from going into the logs?

 

I would prefer not to use the method above as it bypasses the real issue. 

Looking at the SimpleXMLElement documentation along with DOMDocument and DOMXPAth, I can't find a way to validate the actual path.  All of the below throw a warning or notice:

$xpath->evaluate($path);
$xpath->query($path);
$node->xpath($path);

Final question: Is there a "simple" way to validate the $path prior to actually making the call to one of the methods of the various XML PHP classes?

 

Thank you for your time and assistance.
