PHP - parse data from a SOAP response -


i'm using w3 validator api, , kind of response:

<?xml version="1.0" encoding="utf-8"?> <env:envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope"> <env:body> <m:markupvalidationresponse env:encodingstyle="http://www.w3.org/2003/05/soap-encoding" xmlns:m="http://www.w3.org/2005/10/markup-validator">      <m:uri>http://myurl.com/</m:uri>     <m:checkedby>http://validator.w3.org/</m:checkedby>     <m:doctype>-//w3c//dtd xhtml 1.1//en</m:doctype>     <m:charset>utf-8</m:charset>     <m:validity>false</m:validity>     <m:errors>         <m:errorcount>1</m:errorcount>         <m:errorlist>              <m:error>                 <m:line>7</m:line>                 <m:col>80</m:col>                 <m:message>character data not allowed here</m:message>                 <m:messageid>63</m:messageid>                 <m:explanation>  <![cdata[                  page html here                   ]]>                 </m:explanation>                 <m:source><![cdata[ html again ]]></m:source>             </m:error>              ...          </m:errorlist>     </m:errors>     <m:warnings>         <m:warningcount>0</m:warningcount>         <m:warninglist>           </m:warninglist>     </m:warnings> </m:markupvalidationresponse> </env:body> </env:envelope>

how can extract variables there?

i need validity, errorcount , if possible list of errors: line, col, , message :)

is there easy way this?

you can load xml string simplexmlelement simplexml_load_string , find attributes using xpath. it's important register namespaces involved registerxpathnamespace before using xpath.

$xml = file_get_contents('example.xml'); // $xml should xml source string $doc = simplexml_load_string($xml); $doc->registerxpathnamespace('m', 'http://www.w3.org/2005/10/markup-validator'); $nodes = $doc->xpath('//m:markupvalidationresponse/m:validity'); $validity = strval($nodes[0]); echo 'is valid: ', $validity, "\n"; $nodes = $doc->xpath('//m:markupvalidationresponse/m:errors/m:errorcount'); $errorcount = strval($nodes[0]); echo 'total errors: ', $errorcount, "\n"; $nodes = $doc->xpath('//m:markupvalidationresponse/m:errors/m:errorlist/m:error'); foreach ($nodes $node) {     $nodes = $node->xpath('m:line');      $line = strval($nodes[0]);     $nodes = $node->xpath('m:col');     $col = strval($nodes[0]);     $nodes = $node->xpath('m:message');     $message = strval($nodes[0]);     echo 'line: ', $line, ', column: ', $col, ' message: ', $message, "\n"; }
