I am sorry but i m not very good in this script.
for example i have
<?xml version = "1.0" encoding="Windows-874" ?>

      <user>user</user>
      <password>pwd</password>
                <filename>picture.jpg</filename>
      <content>albkja;dlkjoasdihfashdf;kj;eifjo;eijf</content>

if i only want the values in the filename and contents and show it on the other page
Can you give me a sample of how it is done?

Have a look at this example:

<?php

$data = '<?xml version = "1.0" encoding="Windows-874" ?>
<tag>
     <user>user</user>
     <password>pwd</password>
                <filename>picture.jpg</filename>
     <content>albkja;dlkjoasdihfashdf;kj;eifjo;eijf</content>
     <user>user</user>
     <password>pwd</password>
                <filename>picture2.jpg</filename>
     <content>albkja;dlkjoasdihfassdfdshdf;kj;eifjo;eijf</content>
</tag>
';

$xml_parser = xml_parser_create();
xml_parse_into_struct($xml_parser, $data, $vals, $index);
xml_parser_free($xml_parser);
$result = array();
foreach($index['FILENAME'] as $num => $id) {
    $result[] = array(
        'filename' => $vals[$id]['value'],
        'content'  => $vals[$index['CONTENT'][$num]]['value'],
        );
}

// for debugging/understanding the structures:
var_dump($vals);
var_dump($index);
var_dump($result);

$result will contain:
Array
(
    [0] => Array
        (
            [filename] => picture.jpg
            [content] => albkja;dlkjoasdihfashdf;kj;eifjo;eijf
        )

    [1] => Array
        (
            [filename] => picture2.jpg
            [content] => albkja;dlkjoasdihfassdfdshdf;kj;eifjo;eijf
        )

)

This will only work correctly if you have the same count of fielname and contents tag and if the are in the same xml-level.
