[Help] StringRegExp - not getting the last line

[Kyan]

Hi everyone

can somebody tell me what I'm doing wrong here

#include 
$text = "http://www.autoitscript.com/forum/topic/142866-div-value/" & @CRLF & _
"http://www.youtube.com/results?search_query=autoit+tutorials" & @CRLS & _
"http://www.autoitscript.com/forum/topic/142878-filereadline-variables-error/" & @CRLF & _
"http://www.autoitscript.com/forum/topic/142831-need-different-serial-communications-udf/" & @CRLF & _
"https://www.google.com/search?num=10" & @CRLF & _
"http://www.autoitscript.com/forum/topic/142722-generate-program-list/"
$list = StringRegExp($text,"(autoitscript\.com\/forum\/topic\/.*?)\r\n+", 3)
_ArrayDisplay($list)
Exit

What I want is grab all the autoit links but I had no success :s, I specify for start: "autoitscript.com/forum/topic/" and at end: \r\n (line end)

what's wrong for i'm not grabbing the last one? And there's a way to ignore white spaces?

thanks in advance

What are you creating? And you can use S+ instead of V+ if you want.

There's no @CRLF at the end of the last string, that's why it's not picking that one up.

That's a good point, but my example doesn't really care about this. I'm no SRE guru but I am learning slowly but surely. Edited July 30, 2012 by guinness

And I don't need to set the end to use stringregexp?

V = any character that is not a vertical whitespace character.

S = Match any non-whitespace character.

I'm create a app to find urls inside of a txt, the search is set in a input by the user

[guinness]

No you don't, but for good practice I would recommend it as BrewManNH (my colleague) suggested.

you're right, at beginning I used \r\n+|$ but nothing show up

No you don't, but for good practice I would recommend it as BrewManNH (my colleague) suggested.

lol

[guinness]

Did you try my example? I wouldn't say it was the best (as there are many variations with SREs) but it works.

yup, works fine

thanks

SREs?

[guinness]

SREs?

Regular expressions or in AutoIt StringRegExp(Replace), therefore SREs for short.

got it, I hope so

just one last question, for grabbing at least x chars and at most y chars, I set it up like this

StringRegExp($sText, 'autoitscript.com/forum/topic/S{x,y}', 3)

but only grabs the X number of chars, is it normal?

[UEZ]

Here another regex:

$text = "http://www.autoitscript.com/forum/topic/142866-div-value/" & @CRLF & _
"http://www.youtube.com/results?search_query=autoit+tutorials" & @CRLF& _

"http://www.autoitscript.com/forum/topic/142831-need-different-serial-communications-udf/" & @CRLF & _
"https://www.google.com/search?num=10" & @CRLF & _
"http://www.autoitscript.com/forum/topic/142722-generate-program-list/"

$sLast = StringRegExpReplace($text,"(?ms)(?:.*)^(.*)$", "$1")
MsgBox(0, "Test", $sLast)
Exit

UEZ,

I think DiOgO wanted to grab all the autoitscript.com links and was wondering why the last one was missing. Nice idea though.

Strange as when I replace x with 1 and y with 10 it returns 10 characters, as the normal behaviour is to match as many characters as possible.

UEZ,

Ops...did not read the topic carefully!

Then I would add just a @CRLF:

#include <Array.au3>

$text = "http://www.autoitscript.com/forum/topic/142866-div-value/" & @CRLF & _
"http://www.youtube.com/results?search_query=autoit+tutorials" & @CRLF& _
"http://www.autoitscript.com/forum/topic/142878-filereadline-variables-error/" & @CRLF & _
"http://www.autoitscript.com/forum/topic/142831-need-different-serial-communications-udf/" & @CRLF & _
"https://www.google.com/search?num=10" & @CRLF & _
"http://www.autoitscript.com/forum/topic/142722-generate-program-list/"
$list = StringRegExp($text & @CRLF,"(autoitscript.com/forum/topic/.*?)rn+", 3)
_ArrayDisplay($list)
Exit

You don't really need the @CR or @LF in the returned values so replace rn+ with (?:v|$)+

That way it will check for any vertical whitespace or end of string but it won't capture it

$text = "http://www.autoitscript.com/forum/topic/142866-div-value/" & @CRLF & _

strange code, i'm going test it out, thanks

your last way could give empty lines in the array, if i read it right...

UEZ,

I think DiOgO wanted to grab all the autoitscript.com links and was wondering why the last one was missing. Nice idea though.

its just example, why would I want all the autoitscript.com links?

[guinness]

It's what you wrote?! That's why.

return's the last line, I'll add to my examples, one day could be useful, thanks

$aArray = StringRegExp($sText, 'autoitscript\.com/forum/topic/\S{5,10}', 3) ; And without ?.

I set the "Y" as a variable, because It could be changed in the INI file, if is not set then $l = ""'

$l = ',20'
StringRegExp($sText, 'autoitscript\.com/forum/topic/\S{5' & $l & '}', 3)

is not possible do it with vars?

[guinness]

Wrap it in a String function maybe String('autoitscript.com/forum/topic/S{5' & $l & '}')
