Trouble creating array from XML

[middleman666]

Hey All,

I have XML like so:

<?xml version="1.0" encoding="UTF-8"?>
<rsp stat="200">
  <msg>OK</msg>
  <maxorder>25</maxorder>
  <url><![CDATA[http://myurl.com]]></url>
</rsp>

And I use the following function to create an array from the info:

function objectsIntoArray($arrObjData, $arrSkipIndices = array()){
    $arrData = array();

// if input is object, convert into array
if (is_object($arrObjData)) {
    $arrObjData = get_object_vars($arrObjData);
}

if (is_array($arrObjData)) {
    foreach ($arrObjData as $index => $value) {
        if (is_object($value) || is_array($value)) {
            $value = objectsIntoArray($value, $arrSkipIndices); // recursive call
        }
        if (in_array($index, $arrSkipIndices)) {
            continue;
        }
        $arrData[$index] = $value;
    }
}
return $arrData;
}

$xmlUrl = 'http://urltoxmlrequest.com';
$xmlStr = file_get_contents($xmlUrl);
$xmlObj = simplexml_load_string($xmlStr);
$arrXml = objectsIntoArray($xmlObj);

//Return values
$status = $arrXml['@attributes']['stat'];
$url = $arrXml['url'];

$status returns fine, but when I try to get $url it just returns 'Array' which I'm guessing is because the value is wrapped in CDATA tags.

What I'd like to know is how can I reference the <url> value in the xml?

Any help would be great thanks!

I found this solution, on this site

It does not look like the most elegant solution, and could probably be cleaned up w/ regular expressions but im super busy, but you can try it.. (I tried it with your sample XML and it worked for me)

    function uncdata($xml)
    {
        // States:
        //
        //     'out'
        //     '<'
        //     '<!'
        //     '<!['
        //     '<![C'
        //     '<![CD'
        //     '<![CDAT'
        //     '<![CDATA'
        //     'in'
        //     ']'
        //     ']]'
        //
        // (Yes, the states a represented by strings.) 
        //

    $state = 'out';

    $a = str_split($xml);

    $new_xml = '';

    foreach ($a AS $k => $v) {

        // Deal with "state".
        switch ( $state ) {
            case 'out':
                if ( '<' == $v ) {
                    $state = $v;
                } else {
                    $new_xml .= $v;
                }
            break;

            case '<':
                if ( '!' == $v  ) {
                    $state = $state . $v;
                } else {
                    $new_xml .= $state . $v;
                    $state = 'out';
                }
            break;

             case '<!':
                if ( '[' == $v  ) {
                    $state = $state . $v;
                } else {
                    $new_xml .= $state . $v;
                    $state = 'out';
                }
            break;

            case '<![':
                if ( 'C' == $v  ) {
                    $state = $state . $v;
                } else {
                    $new_xml .= $state . $v;
                    $state = 'out';
                }
            break;

            case '<![C':
                if ( 'D' == $v  ) {
                    $state = $state . $v;
                } else {
                    $new_xml .= $state . $v;
                    $state = 'out';
                }
            break;

            case '<![CD':
                if ( 'A' == $v  ) {
                    $state = $state . $v;
                } else {
                    $new_xml .= $state . $v;
                    $state = 'out';
                }
            break;

            case '<![CDA':
                if ( 'T' == $v  ) {
                    $state = $state . $v;
                } else {
                    $new_xml .= $state . $v;
                    $state = 'out';
                }
            break;

            case '<![CDAT':
                if ( 'A' == $v  ) {
                    $state = $state . $v;
                } else {
                    $new_xml .= $state . $v;
                    $state = 'out';
                }
            break;

            case '<![CDATA':
                if ( '[' == $v  ) {


                    $cdata = '';
                    $state = 'in';
                } else {
                    $new_xml .= $state . $v;
                    $state = 'out';
                }
            break;

            case 'in':
                if ( ']' == $v ) {
                    $state = $v;
                } else {
                    $cdata .= $v;
                }
            break;

            case ']':
                if (  ']' == $v  ) {
                    $state = $state . $v;
                } else {
                    $cdata .= $state . $v;
                    $state = 'in';
                }
            break;

            case ']]':
                if (  '>' == $v  ) {
                    $new_xml .= str_replace('>','&gt;',
                                str_replace('>','&lt;',
                                str_replace('"','&quot;',
                                str_replace('&','&amp;',
                                $cdata))));
                    $state = 'out';
                } else {
                    $cdata .= $state . $v;
                    $state = 'in';
                }
            break;
        } // switch

    }

    //
    // Return.
    //
        return $new_xml;

}

So.. to use it:

$xmlStr =  uncdata($xmlStr);
$xmlObj = simplexml_load_string($xmlStr);
$arrXml = objectsIntoArray($xmlObj);

//Return values
$status = $arrXml['@attributes']['stat'];
$url = $arrXml['url'];
echo $url;

Best of luck...
