    time1=time.ctime(mtime)
    for z in glob.glob(folder+"/*.xml"):

        time2=time.ctime(mtime)
        if (time1>time2):
            new_file=x

        else:

Use two variables to keep track of the name and time of the latest file found so far. Whenever you find a later file, update both variables. When your loop is done, the variables will contain the name and time of the latest file.

I'm not quite sure why you have two nested loops in your example code; if you're looking for all *.xml files in the given directory, you only need one loop.

A Pythonic solution might be something like:

folder = "C:/xml"
print max((os.stat(x)[8], x) for x in glob.glob(folder+"/*.xml"))

If you choose the max() solution, be sure to consider the case where there are no *.xml files in your directory.
