I'm trying to parse DYK prep area templates, for example
Template:Did you know/Preparation area 3. Unfortunately, these are more like flat text files than any kind of nicely structured data. The stuff of interest is everything between two HTML comments:
<!--Hooks-->
{{main page image/DYK|image=Melissa Ong.webp|caption=Selfie of Ong, commonly replicated by the Step Chickens<!--the caption length is intentional, it highlights that this image is there for a specific purpose and isn't just any image of Ong – please don't shorten it! Same for the ''(shown)'' –leek -->}}
* ... that "Step Chickens" on TikTok replace their profile pictures with an image ''(shown)'' of '''[[Melissa Ong]]''', whom they call "Mother Hen"?
* ... that '''[[interfaith greetings in Indonesia]]''' include phrases from Islam, Christianity, Hinduism, Buddhism, and Confucianism?
* ... that '''[[Kimmo Leinonen]]''' helped establish both the [[Finnish Hockey Hall of Fame]] and the [[IIHF Hall of Fame]]?
* ... that the [[Pulitzer Prize for Fiction|Pulitzer Prize]]-winning novel '''''[[All the Light We Cannot See]]''''' contains a sympathetic [[Nazism|Nazi]]?
* ... that a {{Convert|10|ft|m|adj=mid|-tall|0}} '''[[Lady Rainier|statue of a woman]]''' in [[Seattle]] was commissioned by a local brewery in 1903?
* ... that ...
* ... that prior to entering politics, '''[[Herbert Salvatierra]]''' led a troupe of [[carnival]] ''[[comparsa]]s''?
* ... that [[Winston Churchill]] published '''[[Are There Men on the Moon?|an essay on extraterrestrial life]]''' during the Second World War?

I can find the comments with Wikicode.filter_comments(). But once I've found the two delimiting comments, how do I grab the text between them? Or is the parser the wrong tool? Would I do better to treat the content of the page as flat text and just iterate over it line by line, teasing it apart with regexes?
