Specific .NET Regex Help

Question

I need a .NET Regex that extracts the "field" and "width" values in the following string:

<element attribute='{field}' attribute='{field,}' attribute='{ field }' attribute='{ field, 0 }' attribute='{field,0}' attribute='{ field, 10 }' attribute='{field,10}' attribute='{ field, 100 }' attribute='{field,100}' />

I need to capture everything between the { and } characters then extract the field and width. Width is everything between the , and } characters. If no , character then width is Null/Nothing.

I am not aware of how I can use Linq to Xml. I need to perform a method call on each match. Would this make a difference? Can you provide an example? — AMissico

@"\{\s*(?<field>\w+)\s*(,\s*(?<width>\d*)\s*)?\}"

Usage: Use Regex.Matches and extract the groups from each

Edit: You could add the static text in the expression too, but that would make it 'harder' to read IMO.
