Need help please

[marvin carandang]

Hello Nedit Experts,

I have a long list of digital pattern and would like to delete certain groups of texts in between. I attached a snap-shot below. ( I just changed the content due to confidentiality reasons):

------------------------------------------------------------------
Page 1 abcdefassdsd,msdskdskskds
njsdsdjskd
...
...
..
....
.....
                                                                                                                                 Example
      < Digital Data>

Page 2 abcdefassdsd,msdskdskskds
njsdsdjskd
...
...
..
....
.....
                                                                                                                                 Example      
    <Digital Data>

...and so on....
-------------------------------------------------------


I want to delete all characters starting from the "space" after the page number until the word "Example". I short, I need the resulting data to be like this:
------------------------------------
Page 1

        < Digital Data>

Page 2

       < Digital Data>

Page 3

... and so on
--------------------------------------
This is thousands of pages long but the pattern is just the same. How do I do that? Thanks for the help!!!

Better to write an awk program.

/^Page.*$/ {
skip=1
}

/^.*Example.*$/ {
skip=0
}

{
if(skip != 0)
{
print
}
}


This is just an indication of what you can do. It won't work properly up front. If you can send me some actual data I might be able to do a better job with 10 minutes of hacking or so.

Better to do it in Perl!

Hello Nedit Experts,

Since nedit's find-replace dialog can use regular expressions it is
quite powerful. If you type the following in the Find field of the
Replace dialog:

(Page\s+\d+).+\n(?n.+?)Example\s*\n

and the following in the Replace field:

\1\n


This should do the job. Of course you need to check the "Regular
Expression" checkbox before hitting the "Window" button.

To understand the above please see NEdit's regular-expressions
documentation. In any case your question is not really an "NEdit"
question, per-se, but more of a regexp-related question. For example
the following Perl one-liner, run from the Unix command-line, does the
job in nearly the same manner - or at least it should :-)

perl -pi.bak -0 -e's/(Page\s+\d+).+?Example\s*\n/$1\n/sg' <input_file>

This will replace the input_file contents and save the original in a
backup input_file.bak.

Cheers,

[marvin carandang]

Hi Kaye,

Thank you very much. I'll try this out.

Regards,

One caveat. The default maximum length of a search/replace string is
possibly not enough. Recent versions of source/nedit.h have:

#define SEARCHMAX 5119

If you are happy building your own version you can increase this and
recompile. I usually change it to 32767.

Hi Andrew,

Thanks for this. This is really interesting to know. I am lucky though, because in this case...the length of the characters that I want deleted is certainly less than 5000.
