html-to-jsonml

A simple parse5-based library for converting HTML text to JsonML. Developed for Webstrates, but can be used for anything JsonML-related.

This replaces the htmlparser2-based jsonml-parse module we previously used, because of its issues parsing <script> tags with <. For instance, htmlparser2 would turn

<script>var x, y, z = x < y;</script>

Into

["script","var x, y, z = x ","< y;"]

Whereas this library gives you

["script",{},"var x, y, z = x < y;"]

With more complicated script code, this gets even worse with jsonml-parse, resulting in odd and complicated objects, rather than plain text as it should be.

To be fair to jsonml-parse, this is not an issue with the module itself, but with the the underlying htmlparser2.

Additionally, it's worth noting that html-to-jsonml (at the time of writing) takes up 459 KB: 29 KB of which is this library itself, and 430 KB on parse5. In comparison, jsonml-parse uses a total 2.6 MB.

Very brief and initial testing shows that jsonmlParse appears to be slightly faster than html-to-jsonml, though.
