newbie qns : how do i use xmldiff?

[No Name]

I had to do some fishing around to figure this much out. Hope it helps.

from input import *     # From the xmldiff directory
from fmes import *      # From the xmldiff directory
from format import *    # From the xmldiff directory
from StringIO import *

# Build your original tree
text1 = '<point><x>1</x><y>2</y><z>3</z></point>'
stream1 = StringIO(text)
tree1 = tree_from_stream(stream)

# Build your modified tree
text2 = '<point><x>2</x><y>2</y><z>3</z></point>'
stream2 = StringIO(text2)
tree2 = tree_from_stream(stream2)

# Compare the trees
formatter = InternalPrinter()
corrector = FmesCorrector(formatter)
corrector.process_trees(tree, tree2)

## OUTPUT: 
## Instructions for modifying original to modified
#  [rename, /point[1]/y[1], x]
#  [insert-after, /point[1]/x[2],
#  <y>
#  2
#  </y>
#  ]
#  [remove, /point[1]/x[1]]
