Examples of com.google.caja.parser.html.DomParser

com.google.caja.parser.html.DomParser
Parses a {@link Node} from a stream of XML or HTML tokens.This is a non-validating parser, that will parse tolerantly when created in HTML mode, or will require balanced tags when created in XML mode.
Since it's not validating, we don't bother to parse DTDs, and so does not process external entities. Parsing will not cause URI resolution or fetching. @author mikesamuel@gmail.com
