foreach dom problem

[beermaker74]

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;
            }

 

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.

Somebody mentioned that the syntax I am using is for php 5. They recomended changing'

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

 

to

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

it is still giving me the same error

 

my main goal in this is to display feeds from google base. So all i need to do is parse and display the feed in my own format. This code does exactly what I want in php 5. but im stuck woth 4.4.4

The DOM interface changed between php 4 and 5.  Check these sites:

 

http://sg.php.net/manual/en/ref.dom.php (v5)

http://sg.php.net/manual/en/ref.domxml.php (v4)

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'); 
             }*/
