I need to validate a web page markup programmatically and I heard it’s possible by using regular expressions. If so how? Is there any other way? (Other than using w3c service)

Use HTML Tidy http://tidy.sourceforge.net/ It both reports on the validity of an HTML document, and can attempt to automatically clean it up. You can run it as a command line application and script it. There are ports or wrappers for it in Java, Perl, and Python.
I also use TagSoup library for Java http://ccil.org/~cowan/XML/tagsoup/ It does a great job of cleaning up badly formatted HTML into valid XML.
