Find name-only ReferenceCitations

[grossir]

Finding ReferenceCitations depend on preceding FullCaseCitations. Currently, we find them using either the defendant or the plaintiff as identified on the FullCaseCitation; and we require a pincite.

	regexes = [
	rf"(?P<{key}>{re.escape(value)})"
	for key in ["plaintiff", "defendant"]
	if (value := getattr(citation.metadata, key, None))
	and is_valid_name(value)
	]
	if not regexes:
	return []
	pin_cite_re = (
	rf"\b(?:{'|'.join(regexes)})\s+at\s+(?P<pin_cite>\d{{1,5}})\b"
	)

To find name-only ReferenceCitations, without pincites, we need to account for a different structure. I think this is easiest for HTML / XML opinions, since the intention of referencing is made explicit by <i> or <em> style tags. Other seemingly obvious structure is the "In $name,". But, see the Halper references that do not conform to in Halper. And see the blue highlight for a case where the party names was not supposed to be a reference

So, I think we should start looking for this kind of citations on HTML / XML documents only, and using the structured text itself, not a cleaned text. This second round of citation finding may benefit also from using the resolved objects metadata #199
