Java library for HTML to Java (POJO) conversion

Using Apache Velocity Api we can combine Java objects (Lists, POJOs etc.) with a (HTML) template and create the (HTML) output.

Is there any Java API that can help reverse engineer this ? The input of this API could be HTML output and the template used, the output should be the data (in Java/XML format) that was used to generate the output.

I am aware of HTTP Unit API, but this just lets me extract HTML elements (like Tables). I am looking for something that extracts the data based on some template.

Solution

  • You can use google protobuf in order to convert messages for different types. And it is very easy to define templates as well. I create JavaScript Objects using JSON.parse(), and in Java you can use protobuf to convert JSON to Java objects.
