Regular Expressions II - Needle I need You.
Dear reader, this is a continuation of this thread:
I opened a new one- because the original thread is solved.
I try to grep a word of a text-value to generate a value with the Generate Attribute oparator.
replaceAll(haystack, "hay (.*) hay", "$1")
...doesn't work. I guess I need needle as result, but it never appears in $1-$3 probably because it's replaced.
Alternative methods like match() and find() only deliver true/false.
Is there an example expression and function which collects an arbitrary word of an attribute containing text, to provide a value for a new attribute (without text-extension)?
