    getElementById in PHP5

    Hi,

    I am working on PHP5 and all the xmldom related extensions are
    installed and on properly.
    I am trying to execute following code but some how not working.


    $doc = new DomDocument();
    $doc->validateOnPars e = true;
    $doc->load('abc.xml' );
    //xml file contains one element with this id
    $elem = $doc->getElementById ( 'eee' );

    if(is_null($ele m)) {
    echo "<br>IT IS NULL";
    }
    else {
    echo "<br>NOT NULL.";
    }

    The output shows me null every time...
    Why is that?????

    Thanks in advance
    Manan Vyas

      The manual hints towards why:

      "According to the DOM standard this requires a DTD which defines the attribute
      ID to be of type ID. You need to validate your document with
      DOMDocument->validate() or DOMDocument->validateOnPars e before using this
      function."

      You've set validateOnParse , but you haven't posted the contents of abc.xml.

      Does it include a DTD that defines ID?

      There is a link in the user contributed notes to the following site that
      explains all:
