parsing xml data return empty value in php

Question

i'm trying to parse data in xml with simple_load_string function in php and it's return an empty data in the $parsed (data parsed) .

the data to parse is like :

<cas:serviceResponse xmlns:cas="http://www.yale.edu/tp/cas">
    <cas:authenticationSuccess>
        <cas:user>yassine458</cas:user>
    </cas:authenticationSuccess>
</cas:serviceResponse>

is that possible to parse data with this format or there is another method to do it .

this is my code :

$xml = simplexml_load_string($result);
$json = json_encode($xml);
$array = json_decode($json,TRUE);
$parsed= simplexml_load_string($result);

i'm trying to convert it to json format

That is not valid XML so it is difficult to say any more than that as I cannot test it — RiggsFolly

When i was working with xml i am facing the same issue but i found this solution and it worked for me

Documentation :- https://github.com/rentpost/xml2array

OR

https://packagist.org/packages/verdant/xml2array

Use

    $xml = '<cas:serviceResponse xmlns:cas="http://www.yale.edu/tp/cas">
        <cas:authenticationSuccess>
            <cas:user>yassine458</cas:user>
        </cas:authenticationSuccess>
    </cas:serviceResponse>';

    $xml2array = XML2Array::createArray($xml);
    echo "<pre>";
    print_r($xml2array);
    echo "<pre>";

Accessing "user"

    echo $xml2array['cas:serviceResponse']['cas:authenticationSuccess']['cas:user'];

Result : -

    Array
    (
        [cas:serviceResponse] => Array
            (
                [cas:authenticationSuccess] => Array
                    (
                        [cas:user] => yassine458
                    )

            )

    )

if you don't want cas: just replace it with "" in xml;

XML2Array is not found when i try to make your code

Ajay Kumar Over a year ago

you have to copy this [github.com/rentpost/xml2array/blob/master/Verdant/… code and make a file with name of XML2Array.php then include this file and it will work

$xml_string = file_get_contents('/path');
$xml = simplexml_load_string($xml_string);
$json = json_encode($xml);
$array = json_decode($json,TRUE);

Then you can use $json or $array as you want.

i find this solution :

$todelete="xmlns:cas=\"http://www.yale.edu/tp/cas\"";

        $result="<cas:serviceResponse xmlns:cas=\"http://www.yale.edu/tp/cas\">
                    <cas:authenticationSuccess>
                     <cas:user>pdurant2</cas:user>
                      </cas:authenticationSuccess>
                        </cas:serviceResponse>";
        if (strpos($result, $todelete) !== false) {
            $result= str_replace($todelete,null,$result);
        }
        if (strpos($result, "cas:") !== false) {
            $result= str_replace("cas:",null,$result);

        }
        if (strpos($result, "/cas:") !== false) {
            $result= str_replace("/cas:",null,$result);

        }
        $parsed=simplexml_load_string($result);

and it's work for me .
