Regular expressions to find number before link?

I want to grab the Google search rank for a site based on a keyword. As an example www.salarymap.com/ ranks in this search for salary finder. A regular expression to grab the number (in my case today I see www.salarymap.com/ as 13.) is a little beyond my current regular expression skill set.

http://www.google.com/ie?q=salary+finder&num=100&hl=en&btnG=Search

Any help with a search rank regular expression is appreciated.

 

Didn't test, but assuming you have the content of that google page in $googlecontent :

<?php
$data = explode("<nobr>",$googlecontent);
foreach($data as $line)
{
	if(preg_match("/www\.salarymap\.com/",$line))
	{
		if(preg_match("/([0-9]){1,}/",$line,$regs))
		{
			print $regs[1];
		}
	}
}
?>

PHP:

This is a VERY big guess and not really a good regex example :$
