I am trying to match all characters between "xAA" and "xFF" but only if theres at least 4 characters between those. Is there a simple way to do this with RegEx?
For example, xAA-12345-xFF should be matched but xAA-1-xFF should be ignored.
My RegEx currently looks like this:
"(?<=\xAA).*(?=\xFF)"
this does match everything between those characters, but i can't find a way on how to only match if at least 4 characters between them, can someone help me?

Quick and dirty hack could be:
"xAA....*xFF"
This requires three (...) characters followed by 0 or more (.*).
CodePudding user response：
Do this:
xAA\S{4,}xFF
\S{4,} matches at least 4 non whitespace characters.
CodePudding user response：
(?<=xAA-)[0-9]{4,}(?=\-xFF)
retracts 12345 from xAA-12345-xFF in case there are only digits
(?<=xAA-)[0-9a-zA-Z]{4,}(?=\-xFF) if letters or digits are possible
