Re: Find and Replace help please

[Matthew London]

Hi Again,

Turns out there are sometimes multiple lines both within my KEEP text and 
in my DELETE text.

le:
&&&
Line or Lines to be KEPT
###
Line or Lines to be DELETED
&&&
Line or Lines to be KEPT
###
etc.

Grateful for your help

Re: Another Newbie GREP help request...

[Matthew London]

I think I see my problem.
I was using "Process Lines Containing" which appears to extract the entire 
line, not matter what I search for.
I used Search with the Extract function, and it works now! 

Thank you

Find and Replace help please

[Matthew London]

Hi,
I have a file with the following:


&&&
TEXT STRING I WANT TO KEEP
###
TEXT STRING I WANT TO DELETE
&&&
TEXT STRING I WANT TO KEEP
etc,
where there is a linebreak after &&&, ###, and all text strings


I need to process this text in two different ways;

1) 
I would like to remove ALL of the following:
###
TEXT STRING I WANT TO DELETE
&&&


So the result is:
TEXT STRING I WANT TO KEEP
TEXT STRING I WANT TO KEEP
TEXT STRING I WANT TO KEEP



2) 
I would like to remove ONLY the following:

###
TEXT STRING I WANT TO DELETE

So the result is:

&&&
TEXT STRING I WANT TO KEEP
&&&
TEXT STRING I WANT TO KEEP
&&&
TEXT STRING I WANT TO KEEP
etc.

Grateful for suggestions on how to do this.
Thank you.
