Class MarkupParser

java.lang.Object
  org.apache.wicket.markup.MarkupParser

public class MarkupParser
extends java.lang.Object

This is a Wicket MarkupParser specifically for (X)HTML. It makes use of a streaming XML parser to read the markup and IMarkupFilters to remove comments, identify Wicket relevant tags, apply html specific treatments etc..

The result will be an Markup object, which is basically a list, containing Wicket relevant tags and RawMarkup.
