It's as simple as this:

String filename1 = url.replaceAll(".*/([^/]+)", "$1");
String filename2 = xml.replaceAll(".*/([^\"]+)\".*", "$1");
if (filename1.equals(filename2))
    xml = xml.replaceAll("(.*/)([^\"]+)(\".*)", "$1" + url + "$3");

Try this:

str.replaceAll("^.*([a-z]+\\.[a-z]+).*$","$1");

The () group the filename to $1.

It doesn't need any regexp.

Use like this:

String code = "...";
String filename = code.substring(code.lastIndexOf("/")+1, code.length());

Edit: And in the second case, you dont need the ending of the tag, so use code.length()-2
