Applying Regex with enclosing string

Question

I'm new to Regex and I'm trying to extract a path from a string found inside a file. But there are many strings that could match the regex I managed to come up with so I came to the conclusion I need to apply the string only if it's enclosed between static strings.

The file looks like this:

14:58:15 [LC] AKF = 0-65535
14:58:15 [THR] CPU 02 : Engine (AFK)
14:58:15 [QA] Result Path : [/some/linux/path/Results/Test_2013_09_12_14_58_15]
14:58:15 [THR] Starting Listener
14:58:15 [THR] Starting Listener

What I'm not sure is if with a regex I could create a pattern that includes the enclosing strings ("[QA] Result Path : " and "]") or if I need to code that logic?

I'm using OpenJDK 1.7.

have you tried something?

You seem to think that you can use only the pattern matching characters in your regex. You can include literals:

  abc.*def

Will search for "abc" followed by any number of any characters followed by "def". If the characters you want to search for are "special", for example a . or a ] then you will need to escape them with a .

\[(.*?)\].*?\[(.*?)\]$

It should capture contents of both brackets.

$ is "end of string", you can omit it if it's not important.
