Let's say I've got the following wikitext:
Some stuff
More stuff
{{MyTemplate}}<!-- comment -->
Blah
Blah
I want to find {{MyTemplate}} but only if it's immediately followed by <!-- comment
-->, and insert something after the comment. Is there anything that does that kind of
pattern matching? I can use mwparserfromhell to find the template:
for node in wikicode.nodes:
if isinstance(node, mwp.nodes.Template) and
node.name.matches("MyTemplate"):
but I don't see any way to match on two consecutive nodes without building my own
little state machine in the loop to keep track of what the previous node was.
