MARC xml and MADS xml are listed at the bottom of each Name page under "Alternate Formats". Since you are using XSL those should work for you way better than a scraped html page in a warc file.
If you know the lccn, you can fetch the single page in the serialization you like:
https://id.loc.gov/authorities/names/n2001028682.madsxml.xml
https://id.loc.gov/authorities/names/n2001028682.marcxml.xml

I've got many pages like
https://id.loc.gov/authorities/names/n2001028682.html (stored in WARC
files)
I've got names.madsrdf.xml.gz which is all the names in madsrdf, but it's disaggregated rather than in the format exampled in https://www.loc.gov/standards/mads/rdf/ so it's not really amenable to processing in XSL. I'd prefer not to spin up a triple store and reasoner of any kind.
I suspect that what I need is the MARCXML, which I'm familiar with manipulating with XSL and has all the subfields I need explicitly marked.
As I work, I've been documenting the differences I find between LoC and wikidata, on the understanding that bridging LCCNs and wikidata is unlikely to be the work of a single person, see https://urldefense.us/v3/__https://www.wikidata.org/wiki/User:Stuartyeates/Wikidata_-_LoC_ontological_mismatches__;!!MrYkk0_46kUzGAu-DfDRZGQ!eCVHA4UrUnLZ4pxsftyKHSpGCX-NTX6bW29M5KEBEtBBodS7cFJzptHPrFpLyJhG_F55JLGs_WLC$
