I modify it to this, it worked fine:

65c65,68
<                 url = re.search(HREF, out_value).groups()[0]
---
>                 try:

It would be useful to see the markdown that led to the exception so that I could reproduce the issue locally.

In 16092:

0.11.5: Handle case in which HREF regex does not find a match

Fixes #12996.
