Getting the DOM for an xhtml document in Java

I'm building a mini web browser that parses XHTML and Javascript using Javacc and Java, and I need to build the DOM. Is there any tool that can help me get the 开发者_如何学运维DOM and manipulate its nodes without having to build it manually as my browser parses the document?

Try using JDOM or Dom4J or reading this question about XML parsers for Java

If you want to handle HTML as found in the wild, trying using JTidy, which will attempt to recover badly formatted HTML for you before rendering it to a DOM.

I'm not sure why you think you need JavaCC to parse an XHTML document. If it's truly valid XHTML, then it's valid XML, and that means that any XML DOM parser will be able to deliver a DOM that you can manipulate. Why not just use the DOM parser that's built into Java or Xerces from Apache or JDOM or DOM4J? Writing your own using JavaCC can be a valuable learning exercise, but I doubt that it'll be better than what you already have available to you.
