[REQ] Tool for Scraping Javascript or specific text on source code

Does anyone knew a tool that will scrape javascript code or a certain text on the source code of a web page? For example, I have a huge list of websites in .csv, or excel, or in notepad, then the tool will count how many website has a javascript using the G analytics, or any other javascript.

Thanks

Not sure if this is what you're looking for, but have a search for Outwit Hub. Its available as a software or Firefox plugin and allows you to scrape data elements from webpages.

I am not sure if some customizable tool exists. I would go for custom made tool. Should be just a few lines of code in php for example.
