Answer 1

$xml = "your xml string";
$xml_object = simplexml_load_string($xml);

or

$xml_file = "path/to/file";
$xml_object = simplexml_load_file($xml_file);

Read up on accessing the data through the resulting XML Object here: http://www.php.net/manual/en/book.simplexml.php

There are several PHP XML handling modules that you can use. DOMDocument is a good one if you are dealing with valid XML, which you appear to be.

The following code will parse your document and output the user name and password found within each <User> tag.

$doc = new DOMDocument();
$doc->load('test.xml');
$userNodes = $doc->getElementsByTagName('Users');
foreach($userNodes as $user) {
  foreach($user->childNodes as $userData) {
    if ($userData->nodeName == 'User') {
      echo "User name: ";
      echo $userData->attributes->getNamedItem('Name')->nodeValue;
      foreach($userData->childNodes as $n) {
        if ($n->nodeName == 'Option' && $n->attributes->getNamedItem('Name')->nodeValue == 'Pass') {
          echo " Password: ".$n->nodeValue."\n";
          break;
        }
      }
    }
  }
}
