Xpath - Getting text from div

Hey folks,

I've tested my xpath in google docs and it's working fine however I can't get it to work in Rapidminer. In the Extract Information operator if I use the query "//h:div[2]/h:div/h:ul/h:li[1]/h:div" I get the result below:

<div xmlns="http://www.w3.org/1999/xhtml" class="stats-value">
  <svg class="icon">
    <use xmlns:xlink="urn:x-prefix:xlink" xlink:href="#trophy" />
  </svg>
  Text that I want
</div>

However I just want the text "Text that I want" not the surrounding html. So I try "//h:div[2]/h:div/h:ul/h:li[1]/h:div/text()". This doesn't give me an error but it's not returning anything, no text at all.

Any help is much appreciated.

Neil.

    @b00122599,

    It seems that your Excel file is broken. I can not open it with Excel and I cannot load the file in RapidMiner...

    Can you share directly the links here ?

    Regards,

    Lionel

    Hi again,

    Sorry no need to share the links ! 

    I was able to load your excel file and run your process....

    @b00122599,

    Yes it's strange.
    To extract the relevant informations, I proceeded in 2 steps.
    But I'm not able to join the 2 resultings example sets (RapidMiner is raising an error).
    Anyway, you can take a look at this process, your information ("Text what I want") is in the second resulting example set...

    Thanks again I think I may need to look at different xpath approach maybe I should be looking at classes. Cheers, Neil.
