Chaining regexes

Petr | Last updated: Jul 31, 2019 05:03PM UTC

Does regex engine in Burp support look-forward regex syntax? I can't get it to work. Suppose I have a text Cookie: xb=451079; localization=en-us%3Bcz%3Bcz; liqpw=1280; liqph=1173; Now I want to match "localization" string only if it's followed by "liqpw" on the same line. The regex for this should be localization(?=.*)(?=liqpw) But I'm getting 0 search results. If the forward-lookup syntax is not available - is there any workaround?
