Re: Error on parsing HTML with libxml

I have looked into the libxml code and I found the method
htmlParseScript() within HTMLParser.c.

https://gitlab.gnome.org/GNOME/libxml2/blob/master/HTMLparser.c

It describes the problem with the "<" character within scripts.
But it offers the possibility to use the recover mode to ignore
the tags.

I have used

xmllint --html -htmlout --recover mypage.html

and it returns the last </td> tag. The PHP equivalent does not work
(there is a flag "recover" on class DOMDocument, but the output is
always the same). So I will look into the DOMDocument code (if it is
available).
