I have been trying to get the SUMMARRY COUNT into a string and then use it to see if it is 0 and if not do something if it is do something else:

please have a look at my code:

 $xml = simplexml_load_string($xml_filename);
 $count= array((string) $xml->FEEDBACKLIST->SUMMARY->COUNT);
    if ($count == "0"){

        $doc = new DOMDocument();
    $xsl = new XSLTProcessor();
    $doc->load($curdir."/feedback.xsl");
    $xsl->importStyleSheet($doc);
    $doc->load($xml_filename2);
    echo $xsl->transformToXML($doc);
    }
    else{
    $doc = new DOMDocument();
    $xsl = new XSLTProcessor();
    $doc->load($curdir."/feedback.xsl");
    $xsl->importStyleSheet($doc);
    $doc->load($xml_filename);
    echo $xsl->transformToXML($doc);    
    }

Can anybody suggest how to do this s this doesn't work

Answer 1

If you define $count as array , you have to check against this array in your if -statement:

if ($count[0] == "0") { // see the index: [0]

As an alternative, don't define $count as array and leave the if -statement as it is:

$count = (string)$xml->SUMMARY->COUNT;

Note: your XML's root <FEEDBACKLIST> is represented in $xml , so do not repeat it.
