Why there is a conflict between DomDocument and DomElement classes?

Write the parser XML document in php using DomXml module.

For this I used the class of functions DomElement. Killed a whole day to sort it out but did. Obviously, this had to be commented in the php file.ini string extension=php_domxml.dll.

Code like this:


...

if(!$dom = domxml_open_mem($xmlstr)) {

echo "Error while parsing the document\";

exit;

}

$root = $dom->document_element();

$nodes = $root->child_nodes();

...


What is the actual problem. For the developed site on another page I used a ready-made parser Twitter feeds that to parse uses the DomDocument class of functions.

Code like this:


...

$feedURL = "twitter.com/statuses/user_timeline/yourtwitteruser...";

$doc = new DOMDocument();

$doc->load($feedURL);

$arrFeeds = array();

...


So, after I uncomment in the php file.ini string extension=php_domxml.dll parser for the tweeter stopped working. If his comment again, then stops working parser for a class of functions DomElement.


I noticed that the parser for Twitter is not working only when already wrote a parser for my xml document. Now I do not know how to get out of the situation.


What's the problem? Or am I still confused or don't understand something? Why the conflict?
