Re: [Htmlparser-user] running StringBean on Node

[Ian M. <ian...@gm...>]

For a recursive function that walks the HTMLParser DOM-like structure,
you can use the NodeTreeWalker class and just keep the text nodes.
That's pretty simple.

If the Node is a CompositeTag, you can (I think) use CompositeTag.accept(sb).
