_StrBetween()

[SmOke_N]

This gets asked for more and more...

This will give you the option of using StringRegExp() or regular string manipulation to get the desired result.

The return is a 0 based array for either or.

Example:

#include <array.au3>
$a = _StrBetween('[18][20][3][5][500][60]', '[', ']');Not using SRE
_ArrayDisplay($a, '')
$b = _StrBetween('[18][20][3][5][500][60]', '\[', '\]', -1, 1);Using SRE
_ArrayDisplay($b, '')oÝ÷ Ù«­¢+Øìôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôôô(ìչѥ½¸9µè}MÑÉ  Ñݸ ÀÌØíÍMÑÉ¥¹°ÀÌØíÍMÑÉаÀÌØí͹°ÀÌØíÙ

Edit:

Forgot a Return...

Edit2:

Changed the default from StringRegExp to regular String Manipulation because most users don't know how to properly use StringRegExp.

Hi,

great. I hope it will be included in standard, because I think the func is very useful.

So long,

... While this strBetween() function is much more complex (which can be good), I've run across a few other strbetween functions.

The following code is pulled from one of the projects. I was using the longer, uncommented function because it was the first thing I tried that worked, while the other two I didn't feel like testing since I already had something that worked. They are much simpler than your function, which may be useful for some, and not useful to others.

Func stringbetween($str, $start, $end)
    $pos = StringInStr($str, $start)
    If Not @error Then
        $str = StringTrimLeft($str, $pos + StringLen($start) - 1)
        $pos = StringInStr($str, $end)
        If Not @error Then
            $str = StringTrimRight($str, StringLen($str) - $pos + 1)
            Return $str
        EndIf
    EndIf
EndFunc

; ALTERNATIVE 1 to the "stringbetween" function
;Func _SRE_BetweenEX($s_String, $s_Start, $s_End, $iCase = 'i')
;   If $iCase <> 'i' Then $iCase = ''
;   $a_Array = StringRegExp ($s_String, '(?' & $iCase & _
;           ':' & $s_Start & ')(.*?)(?' & $iCase & _
;           ':' & $s_End & ')', 3)
;   If @extended & IsArray($a_Array) Then Return $a_Array
;   Return SetError(1, 0, 0)
;EndFunc ;==>_SRE_BetweenEX

; ALTERNATIVE 2 to the "stringbetween" function
;Func _StringBetween($s_String, $s_Start, $s_End = 0)
;   $s_Start = StringInStr($s_String, $s_Start)+StringLen($s_Start)
;   return StringMid($s_String, $s_Start, StringInStr($s_String, $s_End)-$s_Start)
;EndFunc

_SRE_Between() I wrote.

_StringBetween() on the Bottom w0uter wrote.

And the other one you are using only finds one instance, where as the function I wrote above returns all instances.

A suggestion is to read the comments, and only post something when it pertains to the actual thread. Again, you've shown your in-ability to read and understand what's presented.

Edit:

Also, as a side note, the _SRE_Between function you are using there will not work with beta higher than 3.2.1.7.

You're quick to jump.

Yes, this post does not directly relate to the topic of this thread, however, it is a response to a comment of a comment of the topic of this thread. I'm sure you can adjust yourself accordingly. I wrote what I wrote in my comment because I thought that there would be people viewing this forum and wanting something simpler and perhaps faster. Perhaps you are reading me incorrectly, and it is that I over analyze? (Over analyzing to the point that I think about it too much that I miss the basic simple facts, or in this case, I think ahead and answer a question before someone asks it.)

However, to be honest, no I did not understand that the code you wrote does loop for all answers. I didn't a good look at your code and implementation example. And yes, I did read the previous comments before posting, both of which have nothing to do with my comment or did not deal with something that should discourage me for posting what I had posted.

This is a community. We help each other, as cheesy as it sounds.

Anyway, on a lighter note, the script looks good. I'm sure I'll have a use for it later. Bookmarked.

Not quick to jump at all. But you implied that the "code" was overly complicated. It's quite "simple" in comparison to what you are currently using versus the results it (the UDF) returns.

And by comments I meant the header.

BTW, if that's all you want (1 result), then w0uters function at the bottom is much faster than the one you are currently using.

In addition, you should do a time test on the functions, you'll see that StringRegExp(), if used correctly, is much faster than standard string manipulation functions. So if speed is something your after, you may want to look at how to use that type of option.

I've provided a simple example, but StringRegExp() is easily 4 to 5 times faster than standard string manipulation as you are using and or as I've presented with an "easy" option for users that don't have the understanding, nor the want to, to understand StringRegExp().

It's been submitted as a UDF to Jdeb, and seemingly accepted unless something changes from now to then. So you will be able to use it via standard UDF's Friday I believe in the newest beta release (3.2.1.12 I believe).

Post #6 sounded like a politician....... I'll leave it at that.

I was inferring "complicated" as in longer code with more functionality/options. When I meant I was lazy, I really meant I was lazy... and speed wasn't and objective for me. I had just wanted something to work at the time, since I wasn't going to be releasing the script to anyone.

@gafrost, I know what you mean. Sorry about that.

Great job, this should be a Real String Function. or atleast a sticky cuz stringbetween is often needed

[Sorn]

I just stumbled upon this gem, and it's fantastic. But running into a slight problem, I'm sure it's on my end perhaps someone could offer a bit of assistance here, it would be much appreciated.

This is actually parsing html and taking out this chunk

385182122" class="fieldStat"><strong>Apepi</strong>

this is the result of running this strBetween() function, after I got all the data from the webpage in the array I'm running the strBetween function again to trim it down to just 'Apepi' by using the following

For $r = 0 to UBound($myArray,1) - 1
      $tmp = _StrBetween($myArray[$r], '<strong>', '</strong>)
Next

and with this it returns nothing even if I use a _arraydisplay to show me whats in the array.

any ideas what i'm doing wrong here, I'm fairly new to this scripting language but have made leaps and bounds over the past few weeks working with it. The search option on these boards is invaluable (never get rid of it or limit my searches please, mr admin lol)

Thanks

[RazerM]

An array is returned from _StrBetween

[SmOke_N]

This was submitted and is now in the current beta versions of AutoIt, which 2 bugs were already fixed in it.

When using the Regular Expression type, you must be sure (and know how) to use the proper style of display.

[Sorn]

Flippin' weird! after saving the code last night (which I didn't change) exited out of Scite, went to bed, woke up this morning. and the damn code works now. Maybe Internet goblins snuck on my pc last night and fixed the code. Well whatever happen thanks RazorM for the assistance, and once again Smoke_N great work on this.
