Hi everyone, I am struggling writing a right regex that match what I want:
Problem Description: Given a string like this: >>>string = "false_head <a>aaa</a> <a>bbb</a> false_tail \ true_head some_text_here <a>ccc</a> <a>ddd</a> <a>eee</a> true_tail" I want to match the all the text surrounded by those "<a> </a>", but only if those "<a> </a>" locate **in some distance** behind "true_head". That is, I expect to result to be like this: >>>import re >>>result = re.findall("the_regex",string) >>>print result ["ccc","ddd","eee"] How can I write a regex to match that? I have try to use the **positive lookbehind assertion** in python regex, but it does not allowed variable length of lookbehind.
