Thanks, Stefan, for pointing me to lxml. It looks like a good
alternative to SAX in this situation. However, I'm a little confused
as to the best way to remove elements from the tree while keeping
their tail text. This is what I have so far:
context = etree.iterparse("test.xml")
for event, element in context:
for title in element.xpath("child::title"):
element.remove(title)
Do I need to explicitly assign the tail text to either the parent or
the preceding sibling? If so, what's the best way to accomplish that?
Thanks,
-James
