Regex for changing certain pattern in XML file

Question

I need to change the following text

<item id="108-109" name="flowers"/>

To this

<item fromid="108" toid="109" name="flowers"/>

On a file with multiple ocurrences of this 'id="num-num"' pattern. Name and the tag itselt doesn't matter. I've tried lots of different combinations of regex patterns and I can't find one which even finds something. This:

id="([0-9])-([0-9])"

Which in my mind should work is not working.

I'm using Notepad++ regex finder and testing with RegexPal, but after a lot of tries I'm out of ideas.

Oh hell. I don't know where my mind was to forget the +. Thank you! — ranieri

You can do this:

search: id\s*=\s*["'](\d+)-(\d+)["']
replace: fromid="$1" toid="$2"

since your comment, you can simply use:

search: id="(\d+)-(\d+)"

Oh this is a very complex one. I see you also prevented tags like "id = "108-109"". That doesn't happen certainly, but thanks.
