Regular Expression PLEASE HELP!


 Share

Recommended Posts

$time = "23:20:23"

$hey = StringRegExp($time, '(\w:\w:\w)')

If $hey == 1 Then
   Send("Yes")
EndIf

If $hey == 0 Then
   Send("No")
EndIf

 

So i wanna know if my string has any numbers. To do that i used StringRegExp in order to check if the string was containing any numbers.

So simply i want it to read like this: Any:Any:Any including the ":" but it always returns 0 as a "no match" which must mean that this script doesnt work. Any suggestions?

Sfikes,

Try this:

#include <MsgBoxConstants.au3>

$time = "23:20:23"

$hey = StringRegExp($time, '(\d+:\d+:\d+)')

If $hey = 1 Then
   MsgBox($MB_SYSTEMMODAL, "Result", "Yes")
   Else
   MsgBox($MB_SYSTEMMODAL, "Result", "No")
EndIf

The difference is that I am looking for at least one digit in section - you were looking for only a single digit, letter or underscore.

Sfikes,

Reading the Help file page for StringRegExp will explain most of the possible parameters. In this case I used:

Quote

\d  -  Matches any decimal digit

in conjunction with:

Quote
+   -  1 or more

So it will match if we have 3 groups of one or more digits separated by colons.

To be really precise, we should really ask for groups of one or two digits which comes out as:

$hey = StringRegExp($time, '(\d{1,2}:\d{1,2}:\d{1,2})')

Try it with various strings and see how it performs.

RegExes are quite tricky to learn (my brain still bleeds when developing a complex pattern) but are well worth the effort - I always recommend this site as a good place to start.

I never understood (or invested not enough time) StringRegExp. I just tested your eample with a fantasy time:

$time = "239:204:23"

and i got also yes.

AutoBert,

Look at the other pattern I posted - that is more precise and only accepts one or two digits per group.

Just a note about the good links provided above: favor regex101.com as it offers the same regexp flavor as Autoit (PCRE). The reference documentation for PCRE implemented in AutoIt is http://www.pcre.org/original/doc/html/ (AutoIt doesn't implement PCRE2, yet).

This wonderful site allows debugging and testing regular expressions (many flavors available). An absolute must have in your bookmarks.
Another excellent RegExp tutorial. Don't forget downloading your copy of up-to-date pcretest.exe and pcregrep.exe here
