Question

im reading my XML and looping through the child nodes when i move it to another server its stops working, any ideas on why it would stop..

here is the XML:

<masterxmlholder>   
    <userinfo login="user1">
    <rde-idea:lastlogin code="0">Wed Dec 31 17:00:00 MST 1969</rde-idea:lastlogin>
    </userinfo>

    <userinfo login="user2">
    <rde-idea:lastlogin code="4564568522258">Wed Dec 31 17:00:00 MST 1969</rde-idea:lastlogin>
    </userinfo>
</masterxmlholder>

and here is the loop i'm trying to get to the child with

foreach ($xml->children() as $user) {
    echo '<tr><td> Name :  </td><td>' . $user['login'] . $user->lastlogin '</td><td>';

}
echo '</table></center>';

Now I can get the name attribute to display from each of the child nodes, however I can NOT get any of the child's inner nodes to display

this is all trimmed down to give you the idea what im trying to do .. but its basically to see how im trying to access the child nodes and perhaps point out my flaw.

thanks for reading.

The lastlogin info is actually a child of the userinfo node, so you will need to use the children() method again to retrieve the info. Note that in this example, I removed the XML namespace so that I could initialize $xml

$xmlstring = <<<XML
<masterxmlholder>   
    <userinfo login="user1">
    <lastlogin code="0">Wed Dec 31 17:00:00 MST 1969</lastlogin>
    </userinfo>

    <userinfo login="user2">
    <lastlogin code="4564568522258">Wed Dec 31 17:00:00 MST 1969</lastlogin>
    </userinfo>
</masterxmlholder>
XML;

$xml = new SimpleXMLElement($xmlstring);
echo '<center><table>';

foreach ($xml->children() as $user) {
    $name = $user['login'];
    foreach ($user->children() as $child ) {
       $lastlogin = $child;
    }
    echo '<tr><td> Name :  </td><td>' . $name . $lastlogin . '</td></tr>';
}
echo '</table></center>';

I tested the code here: http://writecodeonline.com/php/

Side note, I would not use the center tag, as that is mixing presentation with content, which is frowned upon. Consider using CSS to style and position your table.
