"Extract text from crawled example set"
I am new to rapidminer. I have created a process to crawl the web [which works perfectly fine] and want to extract information from the example set. I'm using the cut document operator however I get an error stating it expects a document instead of example set.
I need to extract a paragraph with a consistent start and end expression from all the web pages that I have crawled.
Can someone advise how should I go about doing this.
