Little help with regex

[mikeparkie]

As I always seem to struggle with regex..

 

I need to a regex to remove a second period from a string e.g. 3.9.9 becomes 3.99

 

The download url is: http://www.getsharepod.com/download/SharePod_3.99.zip

 

But the version page http://www.getsharepod.com/download/ displays 3.9.9, so my download http://www.getsharepod.com/download/SharePod_3.9.9.zip fails.

 

Assistance appreciated.

While you *could* use regex for this, it's really not the best method. This is how I would do it:

 

Set 'version' to the full version capture from http://www.getsharepod.com/download/changelog.aspx :

SharePod ([\d\.]+)\s\(

 

Then set the 'sdownload' url like this:

http://www.getsharepod.com/download/SharePod_{version:split:.:0}.{version:split:.:1}{version:split:.:2}.zip

 

Then put {sdownload} in the 'URL' box.

Oh, and the 'why' - regex is more for capture than clipping, and using the 'split' method as demonstrated above ensures that even once the release is in version 10+ it'll still continue to operate correctly.
