[I know I'm running a one-month old master. I will try to reproduce
this issue again within a day with an up-to-date master unless someone
else does it first. And -Q as well.]
I'm trying out the function `libxml2-parse-html-region' as recommended
by a thread in help-gnu-emacs. However, I discovered that the last
argument of this function does not help me normalize a relative url.
Reproducer:
Visit the attached toy html file. I imagine that it is hosted at
"https://example.com/good/day".
Run this snippet:
(pp (libxml-parse-html-region
(point-min) (point-max)
"https://example.com/good/day"))
Compare it with this snippet:
(pp (libxml-parse-html-region
(point-min) (point-max)))
What I get is this result for both snippets (which is shown twice, once
"pretty-printed", and once returned as a string):
--8<---------------cut here---------------start------------->8---
(html nil
(body nil "\n "
(a
((href . "/hello"))
"1")
"\n "
(a
((href . "../world"))
"2")
"\n "
(a
((href . "good"))
"3")
"\n "
(a
((href . "morning/or/night"))
"4")
"\n "))
--8<---------------cut here---------------end--------------->8---
Notice, that the href values are not normalized: they are copied
verbatim from the original html file.
If I understand the docstring correctly, the last argument of
`libxml2-parse-html-region', when specified as a url string, should be
used as the "base point" of resolving relative paths found within the
html document. But the <a href=xxx> paths are not resolved at the
moment.
