Saving html content with images

looping

Hi,
I'm doing a simple rss reader, so I parse a Rss file to get the "description" field as html content.
I can display this content as Text if I change the "textFormat" property
@textFormat: Text.RichText@

My question is :
How can I save the html content on hard disk (with images) for reading later?
do I have to parse it my self to find image or there is a more easy way?
I'm trying to do this with webview, but I dont have the solution.

Thank you
