[TxMt] Trying to figure how to color code a text file

I am using Textmate with some macro functions to create a CSV file. Sadly I have to do it manually cos the original file had no kind of persistent pattern to define a structure.

Each like has 2 values separated by commas. Each record is separated by a series of dots "."

So for example

....................................................................... This is value 1,"This is value 2 More of value2 More of value2" ........................................................................

I would like to see "This is value 1" in one color and the rest of the string including the quotes in the following lines in another color.

I am trying to make sense of the rules/language grammar in textmate. What language is it? Any help would be greatly appreciated.
