I'm reading the help page of `libxml-parse-xml-region' and noticed this: --8<---------------cut here---------------start------------->8--- libxml-parse-xml-region is a built-in function in =E2=80=98src/xml.c=E2=80= =99. (libxml-parse-xml-region START END &optional BASE-URL) Parse the region as an XML document and return the parse tree. If START is nil, it defaults to =E2=80=98point-min=E2=80=99. If END is nil= , it defaults to =E2=80=98point-max=E2=80=99. ... --8<---------------cut here---------------end--------------->8--- Notice the function signature: it implies that the first two arguments are mandatory, even though the docstring proceeds to talk about what happens when these two arguments are nil. Similarly for `libxml-parse-html-region'. However, both the C source code and experiments show that these two functions do accept 0 arguments. ```emacs-lisp (with-temp-buffer (insert "") (libxml-parse-html-region)) ;=3D> (html nil) ``` I have zero knowledge of dealing with C defuns, so I'll leave fixing this issue to someone more experienced at that. --=20 Best, RY [Please note that this mail might go to spam due to some misconfiguration in my mail server -- still investigating.]
