I have the following code which gets the revision value if it is present
for the input shown above,if there is not "revision=" field it bails out
with the error shown below..when there is no "revision=" tag I want to get
the "default revsion" tag in the input..any inputs on how to do this
withouth changing the existing functionality?

pattern = re.compile('refs/heads/(.*)')
tree = ET.parse('.repo/manifests/test.xml')
root = tree.getroot()
project = root.find("./project[@name='%s']" % name)
revision = project.get('revision')
res = pattern.match(revision)
return res.group(1)
