StringRegExpReplace - back-references --> add this as example in Helpfile

[Zedna]

According to this my post:
​http://www.autoitscript.com/forum/index.php?s=&showtopic=96512&view=findpost&p=693808

There is no example in HelpFile for StringRegExpReplace - back-references.
So this may be added:

$text_in = _ 
'some text1 12/31/2009 01:02:03 some text2' & @CRLF & _
'some text3 02/28/2009 11:22:33 some text4'

; change date format from mm/dd/yyyy to dd.mm.yyyy
$text_out = StringRegExpReplace($text_in, '\x20(\d{2})/(\d{2})/(\d{4})\x20', ' $2.$1.$3 ')

MsgBox(0, "RegExp Replace Test - back-references", 'OLD:' & @CRLF & $text_in & @CRLF & @CRLF & 'NEW:' & @CRLF & $text_out )

Output:

OLD:
some text1 12/31/2009 01:02:03 some text2
some text3 02/28/2009 11:22:33 some text4

NEW:
some text1 31.12.2009 01:02:03 some text2
some text3 28.02.2009 11:22:33 some text4

#cs
\x20 is Chr(32) ie. space at begin and end of date
each part of date is closed in group ()
each group can be back referenced by $n starting from 1 so '$2.$1.$3' means changed order of MM and DD and using dot instead of slash among date parts

That example is far too complex.

That example is far too complex.

I'm curious because there are more complicated ones in the helpfile already.
OK. So here is lightweighted version :-)

$in = 'text1 12/31/2009 01:02:03 text2'

; change date format from mm/dd/yyyy to dd.mm.yyyy
$out = StringRegExpReplace($in, '\x20(\d{2})/(\d{2})/(\d{4})\x20', ' $2.$1.$3 ')

MsgBox(0, "RegExp back-references", $out)

Or even simpler one:

$in = '12/31/2009'

; change date format from mm/dd/yyyy to dd.mm.yyyy
$out = StringRegExpReplace($in, '(\d{2})/(\d{2})/(\d{4})', '$2.$1.$3')

MsgBox(0, "RegExp back-references", $out)

And winner is:

; change date format from mm/dd/yyyy to dd.mm.yyyy
$out = StringRegExpReplace('12/31/2009', '(\d{2})/(\d{2})/(\d{4})', '$2.$1.$3')
MsgBox(0, "RegExp back-references", $out)
