Text Manipulation

Hi there!
Its kinda hard to explain in words, so here's the example:
I would like to change all words such as: goood, good, goodddddd, gggooddd
to just good
Is there an operator that is suitable for this case in rapidminer?

Thanks in advanced!

Hi @tommy1234,

regex and the replace operator is your friend, see attached example:

Best,
