If all you need is to remove payload node ,this could be useful,
s1="<message xmlns='jabber:client' to='n...@host.com'><mynode
xmlns='myprotocol:core' version='1.0'
type='mytype'><parameters><param1>123</param1><param2>456</param2></parameters><payload
type='plain'>...</payload></mynode><x xmlns='jabber:x:expire'
seconds='15'/></message>"
pat=re.compile(r"<payload.*<\/payload>")
s1=pat.sub("",s1)
