Migrate away from myhtml
myhtml's upstream is to be frozen in 3 month, after which it can be considered unmaintained. It would be great to find an alternative.
They do suggest lexbor; libxml provide an html parser, there's google's Gumbo, some random project, netsurf's parser or html tidy's and probably others.
It has to be maintained and to support html5. Some facilities like libxml's XPath support would be nice.
