Question

I have been playing with XML and PHP, I have googled to get the requirement which I am working on but still Im not getting the things the way I wanted.

I have got a XML file with nested variables, I need to parse the variables such as user_id, name and store it in an array, so that I need to use them to change the details in another config file.

For ex: if the user is logged in, using the user_id, i need to parse the all the data of the particular user from the XML file (where the details of the various users are stored).

Until now I could only parse the data and echo all of it but could not find a way to store this parsed information.

This is my test.xml file:

<?xml version="1.0" encoding="ISO-8859-1"?>
<document>
    <user>
        <user_id>0121</user_id>
        <name>Tim</name>
        <file>0121.file</file>
    </user>

    <user>
        <user_id>0178</user_id>
        <name>Henry</name>
        <file>0178.file</file>
    </user>

    <user>
        <user_id>0786</user_id>
        <name>Martin</name>
        <file>0786.file</file>
    </user>

    <user>
        <user_id>1239</user_id>
        <name>Jan</name>
        <file>1239.file</file>
    </user>
</document>

Any valuable information would be greatly helpful

Thanks

Use SimpleXML.

$xml = simplexml_load_file("test.xml");
$user = $xml->xpath("user[user_id = $my_user_id]");

$name = $user[0]->name;
$file = $user[0]->file;
