[Python-markdown-discuss] lxml.etree? (trying to do something with treeprocessor)

[Mark E. <ei...@gm...>]

I'd like to write a treeprocessor that takes the <h2> elements and
stuffs <a name="..."> anchors before them (with the anchorname derived
from the h2 text.)  markdown.etree does give me findall... but the
Elements I get back don't appear to have any sibling operations that
would let me do that.

First question is of course "is there a better way to do that"...
second is, does it make sense to consider lxml.etree another candidate
for etree_loader.importETree?  (That would at least give me
addprevious which does exactly what I'm looking for...)

I did try
   import lxml.etree
   markdown.etree = lxml.etree
(right after the "import markdown" itself) which got a couple of
FutureWarnings and a fatal complaint about null bytes in strings, so
it doesn't Just Work...
