Re: [Python-markdown-discuss] Can't find code "pre" elements in Treeprocessor

[Waylan L. <wa...@gm...>]

I agree, your code should be working ... except that you are also
using the 'fence_code' extension. Unfortunately, the current
implementation of the fenced_code extension does not insert code
blocks into the tree, but uses the raw htmlStash to store the code
blocks.

Try your source text with tradition markdown indented code blocks and
your code should work. If you also want to support fenced code blocks,
then I would suggest looking at the RawHtmlPostprocessor [1]. However,
you will need to manually check to make sure the raw blocks are code
blocks as it handles all raw html blocks - not just code.

I do have plans to refactor the fenced_code extension to be a
Blockprocessor (rather than a Preprocessor), but haven't had the time.
Doing so would solve your problem and also allow fenced code blocks to
be nested in lists, blockquotes, etc. As always, patches are welcome.
