Hi, 

I have a richetext box that users will be filling out lines of information. I need each line independently validated. My regex would be enclosed with a ^ and $ and either all the lines would pass or not.

The number of lines is unknown so a multiline is required but this doesn't seem to work in umbraco.

What's the best way to have umbraco do a multi line regex rather than taking the entire content as one lump?
