New Post: Regex to get the class data from the .css file

Hi ,

How to extract all the .class data from an stylesheet for the classes listed in an string list.

Eg:
1) i have a list of string

htmlClassNames[0]="abc"
htmlClassNames[1]="def"

          .
          .
          .

htmlClassNames[n]="xyz"

2)a css file say style.css
i want to extract all the class data from the style.css
ie .abc{style}

        .def{style}

and also if there say div .abc{style}

how can i achieve this?
