You can use file_get_contents() to capture the webpage to a variable then preg_match() to extract the portion you require.

Post some code if you need specifics.

Hello blaaze,

You can use file_get_contents with a url to extract the raw html http://uk.php.net/manual/en/function.file-get-contents.php
Use str_pos to identify the beginning and end your marker http://uk.php.net/manual/en/function.strpos.php
Use substr to extract the portion of text between your marker position http://uk.php.net/manual/en/function.substr.php
