Extract all Uppercase words from document into new attributes
Hello RM forum,
I'd like to extract all matches from an example set to a new attribute or even to multiple new attributes.
Example text:

The Problem is, that it will only generate the first match as a new attribute:

I want to get a new attribute containing all matches like:
test
DOGS;CATS;BROWN;FOXES
Is there a way to do this in Rapidminer?
Kind regards,
Patrick

This is my RegEx which finds all occurences (operator "generate extract":

@Hyperrick you could play with tokenization on the text minning extension
Its not the final result but it would give you an idea.<?xml version="1.0" encoding="UTF-8"?><process version="9.7.002"> <context> <input/> <output/> <macros/> </context> <operator activated="true" class="process" compatibility="9.7.002" expanded="true" name="Process"> <parameter key="logverbosity" value="init"/> <parameter key="random_seed" value="2001"/> <parameter key="send_mail" value="never"/> <parameter key="notification_email" value=""/> <parameter key="process_duration_for_mail" value="30"/> <parameter key="encoding" value="SYSTEM"/> <process expanded="true"> <operator activated="true" class="text:create_document" compatibility="9.3.001" expanded="true" height="68" name="Create Document" width="90" x="179" y="136"> <parameter key="text" value="We love DOGS.

I would take a different approach to Marco, should achieve a similar result, but puts all the upper case words into a single attribute.
Try this one out and see what you think.
thanks for your response - unfortunately I can't import the process. I keep gettigng an error while importing:
