正则表达式以匹配双引号忽略双引号

Question

I'm trying to match quoted strings in an Excel style formula:

= "Red" & "Blue" & "Green"

The following regex finds the matches nicely:

".*?"

Where I'm having problems though is where the match contains Excel/VBScript escaped quotes (two quotes together):

= "Red" & "Blue" & """Green"" as grass"

I want the double quotes captured inside the one match so I end up with: "Red" , "Blue" , """Green"" as grass" .

I'm doing this in JavaScript.

Answer 1

It seems like this regex will suit you:

/"(?:[^"]|"")*"/g

Explanation:

1. A susbtring that starts with a double quote
2. With anything not quote or double double quote inside
3. Followed by a quote char
