[Plugin: WP Web Scraper] Some help needed with RegEx please

I am scraping an affiliate partner’s resource pages and they have been over-helpful, wrapping the content I need in “document.write(‘[HTML]’);

All I want is the [HTML] in the middle. Is there an easy way I can add some regex or a selector to get rid of the wrapper? Never did get the hang of regex.

Thanks
