PHP Regex extract a javascript variable

This is really probably just a simple string manipulation question that needs a good regex solution.

I have some javascript variables defined in an HTML page. I want to read the page in to PHP, identify the variable I want to change; and update it. The vars look like: 

rsp.pageId = 'sports'

Just to be clear, my script will not know what the value is so in the example 'sports' could be anything; so it's a wildcard where the rest of the string is consistant. I don't know if it would be easier to wrap some comments around the var/value to get to it easier?

I appreciate the help. I'm playing with a DOM manipulation library so I thought about wrapping script tags around each variable and putting an ID on each. I think that would work but seems like the output would be a bit ridiculous.

do you need the spaces around the equals, if not here - preg_replace( "/rsp\.pageId='([a-zA-Z0-9])+'/", "rsp.pageId='blah'" ); if so try here - preg_replace( "/rsp\.pageId\s?=\s?'([a-zA-Z0-9])+'/", "rsp.pageId='blah'" );
