finding keywords within prohtml

I been working on a script that takes an rss feed's links and and searches through the data on those link pages. but because prohtml's htmlList.printElements(); returns a void instead of a string. Is there a way to convert this to a string so I can use an if() to find keywords? Or is there a better way to search through the data? I've included my code.
thanks,
