"How to extract text from multiple webpages"
I like to extract text from blogs. I created a excelsheet with URL to blog and news pages. In rapidminer I use the "Get Pages" operator to extract the page content. At the moment I extract the content of the entire page and I just want extract the text of the blog.
Does anybody knows how to extract only text?
