Simple Text Mining

Hello,

i have to do some reasearches concerning Text Mining with RapidMiner.

I have the RapidMiner 4.6 and the Text PLugin installed.

I successfully crawled  some pages from the web and stored them as html files.
Now i want visualize my results.

For example:
I crawled this Forum and stored the pages whereever the keywords "text" and "mining" appear.
The Crawler stored about 80 html pages.

Is it now possible to extract and visualize e.g. every sentence from every html page where these keywords appear?

Regards
JuWi
