Some more regex help (Solved)

[xcaliber13]

I have  lines of data:

Example:  Encounter Info:   Some different data here       Hospital          This I can find with no issues    (?m)^\bEncounter\b.*\bHOSPITAL\b.*

But what regex would I use to find only the lines that have    Encounter Info:   Some different data here         but with no HOSPITAL  at the end?

So  all the lines of data that I want to find begin with     Encounter Info:  some data here    but no  HOSPITAL  at the end.    How do I stop regex from finding the lines that do have HOSPITAL   at the end of the line?   

I do really appreciate you guys that have a full understanding of regex.    

Thank  you

What's wrong with the pattern

'^Encounter Info:'

Maybe more samples are needed
Do you need to extract some string from there?

FrancescoDiMuro,

           thank you for the reply    Here is an example:

Encounter Info:  NL some different data HOSPITAL          < Do not want to find
Encounter Info:  NL still some different data HOSPITAL    < Do not want to find
Encounter Info:  NL more different data  HOSPITAL         < Do not want to find
Encounter Info:  NL different data here                   < Want to find these lines
Encounter Info:  NL HOSPITAL                              < Do not want to find
Encounter Info:  NL and different data HOSPITAL           < Do not want to find
Encounter Info:  NL HOSPITAL                              < Do not want to find
Encounter Info:  NL and more different data here          < Want to find these lines

All lines are in the same file.

Just create an small script with that data in it and the syntax you are testing which  isn't working  and post that here, as I am never feel the urge to have to retype a data and create the whole script for you.

This should fit your needs:

'(?m)^Encounter Info:.*(?<!HOSPITAL)$'

Basically, the pattern means:
(?m): Modifier. ^ and $ anchors match start and end of line;
^: start of the line;
Encounter Info: literally that string, case sensitive;
.*: every character, from 0 to unlimited;
(?<!HOSPITAL): negative lookbehind. It asserts that the line doesn't have HOSPITAL (case sensitive) at the end of the line;
$: end of the line.

FrancescoDiMuro,

             Thank you!   That pattern works perfectly.   And I really appreciate that you explained why it works.   Again thank you

You're welcome

Nice, if you are sure that no unexpected trailing white(s) space(s) exist at the end of the line  
How would you manage such a case ? 

[FrancescoDiMuro]

Hey @mikell!
Always happy to see you here around.
Well, in that case, a \s* would probably fit in there, isn't it?

'^Encounter Info:.*(?<!HOSPITAL)\s*$'

Did you try it ?

Please, enlight me with your knowledge
Humbly, I'm not really a fan of spaces in RegExes

Hehe  
I asked this to you because the answer seems easy and obvious... but it is not  
... and also because I had to fight a little to find it. There are certainly other ways but I like this one 

#Include <Array.au3>

$txt = "Encounter Info:  NL some different data HOSPITAL    " & @crlf & _ 
    "Encounter Info:  NL still some different data HOSPITAL  " & @crlf & _ 
    "Other line:  NL more different data  " & @crlf & _ 
    "Other line:  NL more different data HOSPITAL " & @crlf & _ 
    "Encounter Info:  NL more different data  HOSPITAL  " & @crlf & _ 
    "Encounter Info:  NL different data here  " & @crlf & _ 
    "Encounter Info:  NL HOSPITAL and something more, keep this ! " & @crlf & _ 
    "Encounter Info:  NL and different data HOSPITAL    " & @crlf & _ 
    "Encounter Info:  NL HOSPITAL  " & @crlf & _ 
    "Encounter Info:  NL and more different data here  "

;$res = StringRegExp($txt, '(?m)^Encounter Info:.*(?<!HOSPITAL)\s*$', 3)

; case 1, fire lines ending with HOSPITAL + anything else
;$res = StringRegExp($txt, '(?m)^Encounter Info:(?|.*HOSPITAL(*SKIP)(*F)|.*)$', 3)

; case 2, fire lines ending with HOSPITAL + "0 or more white spaces" only
$res = StringRegExp($txt, '(?m)^Encounter Info:(?|.*HOSPITAL\h*$(*SKIP)(*F)|.*$)', 3)

 _ArrayDisplay($res)
