Concatenate examples from XML files
I have a bunch of XML files, that I need to import in Rapidminer and extract some elements.
In each file the text is spread between several <p> tags. In the output example set I can get an example per <p> tag with the file names duplicated:
I would like to concatenate the examples of the same files to get all the texts from <p> tags in the same cells:
I followed this thread but I'm a real beginner and I didn't really understand how it worked:
In my case it doesn't really worked. I have the message "Undefined macro: File_value" where in the example process I used the macro didn't seem defined at this step.
Any help would be appreciated!
