Class AbstractMarkupParser

java.lang.Object

org.apache.wicket.markup.AbstractMarkupParser

Direct Known Subclasses:

MarkupParser

public abstract class AbstractMarkupParser
extends Object

This is a base 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.. Please see WicketMarkupParser for a parser preconfigured for Wicket.

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