    appendData() DOM

    Hello everyone. I've been looking for examples on this:

    PHP: 404 Not Found
    http://www.php.net/manual/en/functi...-appenddata.php
    PHP is a popular general-purpose scripting language that powers everything from your blog to the most popular websites in the world.


    but can't really find one. I've got a function that generates a return value
    in HTML, and need to append that to the body tag of my document. So I've
    captured the contents of the page with output buffering, and have loaded it
    into the PHP DOM. I've isolated the body element:

    ,----[ php ]
    $dom = new DomDocument;
    $dom->LoadHTML($buff er);
    $body = $dom->getElementsByT agName('body');
    $body = $body->item(0);
    `----

    And want to do the following:

    ,----[ php ]
    $body->appendData($ht ml);
    `----


    Of course as the appendData method is a member of the DOMCharacterDat a
    class, I get an error:

    Fatal error: Call to undefined method DOMElement::app endData()

    But how can I access the appendData() method to get the results I want?

    Thanks everyone,

    James

    ps. This is my first post to a newsgroup... Sorry if I'm posting this

      CDATA is data encapsuled between '<![CDATA[' and ']]>' markers. The
      advantage of CDATA sections is that you can put anything in between,
      including invalid xml and/or characters as these sections are ignored by the
      parser.

      But what you probably need is just to append a value to the body tag's node
      value, which is done as follows:

      $buffer = '<html><body>bl a</body></html>';
      $dom = new DomDocument;
      $dom->LoadHTML($buff er);
      $body = $dom->getElementsByT agName('body');
      $body->item(0)->nodeValue .= ' bla';

      // Prints: <html><body>b la bla</body></html>
      print $dom->saveHTML();

      Posting is fine and even better then from some 'experienced' posters.

          I was actually really trying to do something very similar to what you've got
          above. My issue was that when I set

          $body->item(0)->nodeValue .= '<b>blah</b>';

          The tags would get a treatment with htmlentities(). I tried turning that
          behavior off:

          $dom->substituteEnti ties = false;

          But that didn't really do what I wanted. The CDATA markers do exactly what I
          need.
