Another method more efficient

<?php

    function get_nodes2($node, $type, &$result)

    {

      if($node != null)

      {

        if($node->id == $type)

          $result[] = $node;

        if($node->child != null)

        {

          foreach($node->child as $child)

          {

            get_nodes2($child, $type, &$result);

          }

        }

      }

    }

?>

I have found no documentation on this method, and it is not part of PHP 5.1.2 .  I am guessing as to its use in the example below.  I hope this helps anyone who does have access (perhaps with a CVS-based build of PHP) to this method.  I also hope that this method will be available soon.



<?php

// call a function which prints all the IMG nodes in a URI

print_img_nodes_for_uri("http://www.php.net/");

function print_img_nodes_for_uri($uri) {

    // create a tidy object for the uri given

    $tidy->parseFile($uri);

    // clean the tidy object

    $tidy->cleanRepair();

    // get the cleaned output and put it in a tidy_node

    $tidy_output = tidy_get_output($tidy);

    // get just the body and put it in a tidy_node

    $body = tidy_get_body($tidy);



    // using tidy_node->get_nodes on the tidy_node $body

    // with the TIDY_TAG_IMG constant, build an array of 

    // all the IMG nodes



    // This produces a FATAL ERROR in PHP 5.1.2:

    // Fatal error: Call to undefined method tidyNode::get_nodes()

    // I do not know what in what version of PHP this method

    // will be available



    $img_nodes = $body->get_nodes(TIDY_TAG_IMG);



    // begin printing the IMG nodes

    print("<br>\n --- Begin img nodes for $uri --- <br>\n");

    // using foreach, loop through each IMG node

    foreach( $img_nodes as $img_node ) {

        // print the current node, using htmlspecialchars() to convert

        // HTML characters to web printable format

        print("img_node=" . htmlspecialchars($img_node) . "<br>\n");

    }

    // finish printing the IMG nodes

    print("<br>\n --- End img nodes for $uri --- <br>\n");

    return(0);

}

?>
