HtmlHandler, for normalizing tag cases #24

wants to merge 471 commits into from

10 participants


As I thought through #20 and #22, I realized that the problem was not with the parser itself, but rather the results the parser created. Rather than hacking on the parser and breaking things like RSS/XML support, I decided a better approach would be to create another handler, called HtmlHandler. It embraces the case-insensitive nature of html tags, and toUpperCase()'s all tag names to respect the standard. When reserializing, the printHtml method (provided by tomdz) now toLowerCase()'s all tags, because it's printing HTML, not XML/RSS.

I've updated all tests, as well as added a few to test for scenarios where tags have mixed cases. This fork is currently in production on

Please let me know any thoughts, as I'm more than willing to hear alternate opinions!
