... I can't get my webserver upgraded? How would I do the same thing in php4?
Hint: In PHP 5 these two lines:

$filelocs = $value->getElementsByTagName("fileloc");
$fileloc = $filelocs->item(0)->nodeValue;
could be written as one:

$fileloc = $value->getElementsByTagName("fileloc")->item(0)->nodeValue;

Another hint that doubles as a tip: you don't need to use a different variable every time.

Yea I have to admit I was being a little silly with that question. I wasn't really being clear. I have a script that aggregates rss feeds for an index to my site. I copied this script from an acquaintance. I think he wrote it for php5 and the DOMDocument APIs are all different for 4. And I can't seem to find good documentation for the API version my server is using. Neither the 4 or 5 api documentation matches the errors I'm getting for the DOMDocument constructor. For php5 the constructor requires no aruguments and has a "load" method to load pages from http requests. PHP 4 documentation says that the DOMDocument object takes two string arguments for "version" and "encoding". The version on my server appears to want a string that contains the xml code because it is present an error that says expect "<" tag.

Here is the script. Any advice on porting it to php4 or help with figuring out what version is running on my hosting companies web server would be greatly appreciated.

$list = array();

$rss = new DOMDocument();

foreach ($feeds as $name => $feed) {

/* $rss -> load($feed); */
$rss = new DOMDocument();

$items = $rss -> get_elements_by_tagname("item");

Ah, so it's a totally different problem and hence ought to be in a totally different thread. Probably a different forum, in fact.

PHP 4 and PHP 5 do not use the same DOM extension. PHP 5 uses DOM and PHP 4 used DOMXML. Stuff written for one will not run in the other.

You might also want to use [php]...[/php] tags around your PHP code or people won't bother trying to read it.
