Question

if($xml = simplexml_load_file($validationURL . "&output=soap12"))
{
   echo "Success";  
}
else
{
    echo "Failed";
}

So This always fails. $validationURL is “http://validator.w3.org/check?uri=http://uvm.edu/~mfurland/cs148/assign1/projects.php”

http://validator.w3.org/check?uri=http://uvm.edu/~mfurland/cs148/assign1/nav.php&output=soap12 works in a browser, but it isn’t working in my code. If I use file(), I get an array, but it’s all strings with a bunch of characters I can’t see. Like it has a twenty or thity character string that looked like ” 0 “. What am I doing wrong here? Nobody else seems to have this issue.

Contents of the file when you look at in a browser:

    <m:uri>http://www.uvm.edu/~mfurland/cs148/assign1/projects.php</m:uri>
    <m:checkedby>http://validator.w3.org/</m:checkedby>
    <m:doctype>HTML5</m:doctype>
    <m:charset>utf-8</m:charset>
    <m:validity>true</m:validity>
    <m:errors>
        <m:errorcount>0</m:errorcount>
        <m:errorlist></m:errorlist>
    </m:errors>
    <m:warnings>
        <m:warningcount>1</m:warningcount>
        <m:warninglist></m:warninglist>
    </m:warnings>
</m:markupvalidationresponse>
</env:Body>
</env:Envelope>

I often have to communicate with web services that use namespaces. There’s two options available to you; register the namespace with SimpleXML, or remove the : character from the tags.

Removing the : might be easier, but might not be the neatest option, depending on what you want to do with the data.

To remove the colon character:

$xml_content = file_get_contents($validationURL . '&output=soap12');
$xml_content = preg_replace("/(<\/?)(\w+):([^>]*>)/", "$1$2$3", $xml_content);
$xml = simplexml_load_string($xml_content);

Alternatively, to work with the namespaces, see this article Parse XML with Namespace using SimpleXML
