StringRegExp() and group patterns

[LxP]

Hi guys,

Here's some code:

#Include <Array.au3>

Local $TestCase1 = '    This line starts with some spaces'
Local $TestCase2 = 'This line starts with no spaces'

Local $RegExp = '^(\s*)(\w+)'
Local $Results1 = StringRegExp($TestCase1, $RegExp, 1)
Local $Results2 = StringRegExp($TestCase2, $RegExp, 1)

_ArrayDisplay($Results1, '$Results1')
_ArrayDisplay($Results2, '$Results2')

Here's the output I expect:

[0] = (some spaces)

[1] = This

[0] = (empty element)

[1] = This

Here's what I'm receiving:

[0] = (some spaces)

[1] = This

[0] = This

If StringRegExp() is asked to 'return an array with the text that matched all the group patterns' (i.e. flag 1) then is it fair to expect that the returned array contain as many elements as there are groups? With the current behaviour it is not possible to determine which element matches which group if not all groups return data. Edited October 30, 2005 by LxP

Hi!

There are several problems with StringRegExp(). Have a look at the bugs forum and make sure to use the latest beta.

I had a quick look at the open StringRegExpReplace()-related bugs and if this could be classified as a bug then I think it would be a new one.

I'm not sure if it is regarded as buggy behaviour though, so I thought I should post here first.

LxP, I think things should behave as you describe so I would report it as a bug.

Thanks Valik. Reported.
