[Solved]Syntax Xpath

Question

I can't find the right syntax for Xpath tot extract data.

Right now I'm experimenting in google docs to find the richt syntax. I'm trying to pull the review text from the following url: http://www.tripadvisor.nl/ShowUserReviews-g188590-d2333086-r155685828-EasyHotel_Amsterdam-Amsterdam_North_Holland_Province.html#REVIEWS

With this syntax I get one specific review: //*[@id="review_155685828"]/text()

I want to extract all re reviews on that page, but I can't find the right syntax. Does anabody knows what synatax I have to use to retreive all the review text from that page?

Next step is to use the Xpath in rapidminer.

Thanxs, Arno

Hi Marcin, Thanks al lot. That works fine!

The problem is that you have one document and the "Extract Information" operator will take the first match it finds for every document. So you have to cut the document by your XPath (without text()) with the "Cut Document" operator. This will create several document for which you can extract the content separately. See the process below. BTW: With the "Web Mining" extension you can crawl and process the HTML within a single RapidMiner process.

Thanks Marcin,
Much better.  :) . The only thing is that by using the Xpath syntax of rapidminer I get 1 review and using the same syntax in Google Docs I get all 6 reviews. Do you know how that is possine?

Thanks, Arno
