I am programming in Python 3.4.
I am reading lines in different files and when I get to the line containing a specific string I want extract only the path string from that line.
Example:

line in file is: 

```
TEST_CASE_CHECK = require("TestCases/AOL/TU_Extract_Log_Details")

```

I search for: `require("TestCases`

I want extract only: `TestCases/AOL/TU_Extract_Log_Details`

I know this can be done with regex but I could not figure out how to do it.
