Extract string found in line

[Lee Hinde]

I am parsing apache log files. This is the grep pattern I'm using:

GET /public/search/\?q=(\w|\+|\.|-)+

works fine. But I want to extract just the text that matches that string
and lose all the rest of the line.

How would I do that?

Hey Lee,

When making these kinds of requests it's always better if you provide an actual 
sample of the data you're working with.

Just looking at it I could say:

Find:

.*(GET /public/search/\?q=(\w|\+|\.|-)+).*

Replace:

\1

But I'd much rather see the data and actually test my solution.

For that matter this seems like a job for a Perl filter.

The longer string is like this:

 - [27/Mar/2014:11:06:59 -0700] "GET /public/search/?q=lunch+time+boot+vamp
HTTP/1.1" 200 18045 "http://www.example.com/public/minion/edit/177304";

Here's a little Applescript snippet that works in BBEdit:

find "src=\"([a-zA-Z0-9\\=\"\\.\\-_]+)/([a-zA-Z0-9\\=\"\\.\\-_]+)\"" searching 
in imgDocRef options {search mode:grep, starting at top:false} with selecting 
match

set imgSrc to grep substitution of "\\1"
set imgName to grep substitution of "\\2"

Don't know if it works in anything else.

Hey Lee,

That makes it much easier.

This filter will remove all text except for what you want.

#! /usr/bin/env perl 
use v5.010; use strict; use warnings;

while (<>) {
say $1 if ( m!.*(GET /public/search/\?q=(\w|\+|\.|-)+).*! );
}

The regex is between the two exclamation points and can be altered to suit.

Save the filter here:

~/Library/Application Support/BBEdit/Text Filters

Access via the menu {Text}-->{Apply Text Filter}

These are fast, flexible, and efficient.

I give often-used filters a keyboard shortcut, and I have a Keyboard Maestro to 
actually open the {Apply Text Filter} menu from whence I can type-select to 
access the filter I want.

Hey Lewis,

BBEdit's AppleScript syntax is BBEdit-specific, but it will most often work in 
TextWrangler by simply changing to tell application "TextWrangler".  (Except 
when a function that's available in BBEdit isn't available in TextWrangler.)

Here's a turnkey snippet for Lee's task:

---
tell application "BBEdit"
  tell front text window
replace ".*(GET /public/search/\\?q=(\\w|\\+|\\.|-)+).*" using "\\1" 
options {search mode:grep, case sensitive:false, starting at top:true}
  end tell
end tell
---

Unlike the Perl filter I posted it will leave lines that don't match the 
regular expression intact.
