Assuming this is part of an xml file, I wouldn't use regex. Because the regex will become very complex (and hard to read) as your xml file becomes more complex.
I would use an xml parser which will handle the xml-namespaces, the CDATA and more.
Btw: why are there slashes by the attribute? Did you copy it from a String literal?
