Summary

There is an issue on function:

PEReference | ::= | '%' Name ';'

It's similar to the EntityRef one, so maybe easy to implement.
Maybe that's the cause of the issue.

Side note, just wondering, is it worth to develop our own XML parsing lib? Maybe it's better to use an existing, well-mantained FOSS one?

Operating system

Linux

Steps to reproduce

1. Go to https://yewtu.be/watch?v=5OYawYN9ZCs (or any Invidious video page really)
2. There seem to be an issue when parsing XML related to DASH. See here:

[dash @ 0x563d6ef169c0] Unable to parse '' - missing root node

Expected behavior

The thing should parse correctly and without error

Actual behavior

Parsing error

URL for a reduced test case

Not vailable

HTML/SVG/etc. source for a reduced test case

Couldn't extract a minimal case but the Invidious site still provide plenty

Log output and (if possible) backtrace
