问题 I'd like to convert html to plain text. I don't want to just strip the tags though, I'd like to intelligently retain as much formatting as possible.

问题 I am new to Nokogiri and XPath, and I am trying to access all comments in a HTML or XML fragment. The XPaths .//comment() and //comment() work when I am not using the fragment function, but they do not find anything with a fragment. With a tag instead of a comment, it works with the first XPath.
