from elementtree import ElementTree as et
tree = et.parse("testxml.xml")


for t in tree.getiterator("SERVICEPARAMETER"):
        t.set("Semantics", "localId")


tree.write("output.xml")
                                             Is this code
complete,where are you replacing the localid with "datapackageid",and
where is the new xml being stored.
