Need help with Regular Expression

I know next to nothing about RegEx.  I'm using Textpad, which uses RegEx to do search/replace.

I have a large file that I want to condense.  It's a DNS table.

In this case, I want to find all lines that end in 'B&P" )' and replace the entire line with 25spaces followed by TXT ( "B&P" )

Here's a sample.  Can someone help me with this?

183.142.x.x         A
                        TXT      ( "damon somers on 2/23/2005 6:26:45 AM B&P" )
                        TXT      ( "dave orines on 2/23/2005 6:26:48 AM B&P" )
                        TXT      ( "franklyn abeyta on 2/23/2005 6:26:43 AM B&P" )
                        TXT      ( "guadalupe strysko on 2/23/2005 6:26:42 AM B&P" )
                        TXT      ( "laurence blackshear on 2/23/2005 6:26:44 AM B&P" )
                        TXT      ( "lyndon plazza on 2/23/2005 6:26:46 AM B&P" )
                        TXT      ( "patrick doell on 2/23/2005 6:26:41 AM B&P" )
                        TXT      ( "rocky liem on 2/23/2005 6:26:43 AM B&P" )
                        TXT      ( "vincent stern on 2/23/2005 6:26:46 AM B&P" )
48.142.x.x          A
                        TXT      ( "daniel spooner on 2/2/2005 12:30:40 AM B&P" )
                        TXT      ( "glen schwalenberg on 2/2/2005 12:30:39 AM B&P" )
                        TXT      ( "vito vierra on 2/2/2005 12:30:38 AM B&P" )
                        TXT      ( "ward hope on 2/2/2005 12:30:37 AM B&P" )
                        TXT      ( "branden kriege on 2/2/2005 12:30:36 AM B&P" )
                        TXT      ( "zane duenas on 2/2/2005 12:30:34 AM B&P" )
                        TXT      ( "vincenzo danesh on 2/2/2005 12:30:34 AM B&P" )
                        TXT      ( "leroy bauman on 2/2/2005 12:30:33 AM B&P" )

Raymum: this editor is strange, not sure what regex version they implement
anyhow, yeah, last occurrence would be:
Search for:^.+B&P"\ ?.$
Replace with:                        TXT \(\"B\&P\"\)

I don't know about implementing this in your program but the expression you want is.


It will identify the lines you mentioned.  Most like the replace will require you to type the 25 spaces and then TXT ( "B&P" ).  In other words in the box to specify the text to replace the match with type [25 spaces]TXT ( "B&P" ).  [25 spaces] in the previous sentences is for literally 25 spaces.

Let me know if you have any questions or need more information.

The example is the "before", correct?

thus the "AFTER" would be something like

                         TXT ( "B&P" )?

Whoa, running TextEdit, it's regex is pretty brutal. (Running through wine on linux, at least)
Anyhow, click search/replace, select REGEX
search for -----------><b>^.*B.P</b><------------------
Replace with ---------------><b>             TXT \(\"B\&P</b><----------------- (increase the number of spaces as you wish)

Hmm, let me try that again
Search for: "^.*B.P"
Replace with: "                         TXT \(\"B\&P"
will look for it at the end of the string; not the first occurrence of it

achille - your final one worked with just a few minor tweaks to the spacing.  Thank you!  I'm posting another one with similar issue that I've never been able to figure out.
