  • And where are the tags (which are in the title) if the text says not to search between tags but between ordinary words, as in plain text. And by the way, what were you trying to do on your own - Mike

For example, in python:

 import re re.findall(r'(?<=\[CDATA\[).*?(?=]])', 'abc[CDATA[xyz]]----[CDATA[***]]bla-bla') # --> ['xyz', '***']

Here:

(?<=\[CDATA\[) - look-behind, what should precede the desired

(?=]]) - look-ahead, what should go after the desired

.*? - we are looking for any characters, non-greedy search

As a result, we are looking for the minimum number of any characters between look-behind and look-ahead.
