Remove all blank rows with RegexReplace node

[janszky_nav]

Dear Knime Members,

I would like to ask some help.
I have a content text, az it has some blank rows. I try to remove it, but isn’t working my methode. I checked my methode in Regex101, it is working there.

What is my fault?

Thank you.

Hi @janszky_nav

You’re close, but if you use regexReplace($Content$,"[\\r\\t\\n]" ,"") it should get you some better results.

Dear ArjenEX,

Yes, thank you, but in the middle of the text “…Lea is his SisterBut it is a …” concat two words.
Later I would like to sorting (Sorter node) (TF/DF methode) them.

have you tried checking the length of the row as filter instead?
