I'm absolutely not a regex guru so I'm surely missing something. The strings I'm dealing with are similar to formulas, let's say something like: > > '$["simple_input"]+$["messed_\\"_input"]+10' > > Thanks for any help! > Your original post said you wanted to match strings like: $"somechars_with\\"doublequotes". This regex will do that: ur'\$"[^"\\]*(?:\\.[^"\\]*)*"' However, now you say you want to match: '$["simple_input"]' This is different; it has '[' immediately after the '$' instead of '"'.
