function simplexml_load_string doesnt exist in php4

Hi,

i installed CiviCRM 1.7.beta.9239 recently on my server which works with drupal 5.1 . The problem is when i try to activate google maps in civiCRM after entering google api key for my site and enabled it in one civiCRM profile. When i save data in one another profile where this google maps is not even enabled i get following error:

Fatal error: Call to undefined function: simplexml_load_string() in /home/thinkind/public_html/den/modules/civicrm/CRM/Utils/Geocode/Google.php on line 133

I guess this is coming because i am using php4.4 on my server where as simplexml_load_string() function exists in php5 onwards.

I found similar problem sometime back when i was creating my own mashup using yahoo apis, to solve this problem i used yahoo DOM parser for php4 given at http://developer.yahoo.com/php/samples/parse/parseDOMXML.txt .

You can use this code with statement like :

if(!function_exists('simplexml_load_file'))
