foreach dom problem

ok i am trying to parse some xml and it is becoming a royal pain in my arse.

$base = 'http://google.com/base/feeds/snippets/-/';
$params = 'rental+%5blocation:@%22San+Francisco,CA%22%2b50mi%5d&max-results=3';

$url = $base . 'housing?bq=' . $params;

$c = curl_init($url);
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($c);
curl_close($c);

$dom = domxml_open_mem($response, DOMXML_LOAD_PARSING, $errors);

  foreach ($dom->documentElement->childNodes as $books) {
     if (($books->nodeType == 1) && ($books->nodeName == "entry")) {

          foreach ($books->childNodes  as $theBook) {
              if (($theBook->nodeType == 1) &&
            ($theBook->nodeName == "id")) {
                 $id = $theBook->textContent;
            }

Code (markup):

It gives me an error in the foreach statement. It works fine on my local machine with php5. But not on my server with php4.4.4

here is the error
Warning: Invalid argument supplied for foreach()
before I had
$doc = new DOMDocument();
$doc->load( 'books1.xml' );
to start the dom and I was getting errors. undefined function etc. dom needs a parameter. Once again worked fine on php5 but not on my server. So i changed that to
$dom = domxml_open_mem($response, DOMXML_LOAD_PARSING, $errors);
and that seemed to solve that problem but then the foreach problem came up. thanks

 

The DOM XML extension is different in PHP4, from the PHP website:

You can make it work, but it's not interchangable between PHP4 and PHP5, so your code:

foreach ($dom->documentElement->childNodes as $books) {

Code (markup):

would become:

foreach ($dom->document_element->child_nodes as $books) {

Code (markup):

in PHP4. Note that the above is untested - I don't have access to a server with the DOM XML extension loaded into PHP4 at present.

 

Ok going thru the xml dom for php 4 i came up with this that works
for anybody else having the same problem

$dom = domxml_open_mem($response, DOMXML_LOAD_PARSING, $errors);
$noderoot = $dom->document_element();
$childnodes = $noderoot->child_nodes();

  foreach($childnodes as $books) {

     if (($books->node_type() == 1) && ($books->node_name() == "entry")) {
          foreach ($books->child_nodes()  as $theBook) {
              if (($theBook->node_type() == 1) &&
            ($theBook->node_name() == "id")) {
                 $id = $theBook->get_content();
				 
            }
			
			if (($theBook->node_type() == 1) &&
             ($theBook->node_name() == "published")) {
                 $published = $theBook->get_content();
             }
			 
             if (($theBook->node_type() == 1) &&
             ($theBook->node_name() == "updated")) {
                 $updated = $theBook->get_content();
             }
			 
			/* if (($theBook->node_type() == 1) &&
             ($theBook->node_name() == "category")) {
                 $category = $theBook->get_attribute('term'); 
             }*/
