<P>
Receive notification of the logical content of a document.
<blockquote>
<em>This module, both source code and documentation, is in the
Public Domain, and comes with <strong>NO WARRANTY</strong>.</em>
</blockquote>
<p>This is the main interface that most SAX applications
implement: if the application needs to be informed of basic parsing
events, it implements this interface and registers an instance with
the SAX parser using the <A HREF="../../../org/xml/sax/XMLReader.html#setContentHandler(org.xml.sax.ContentHandler)"><CODE>setContentHandler</CODE></A> method. The parser uses the instance to report
basic document-related events like the start and end of elements
and character data.</p>
<p>The order of events in this interface is very important, and
mirrors the order of information in the document itself. For
example, all of an element's content (character data, processing
instructions, and/or subelements) will appear, in order, between
the startElement event and the corresponding endElement event.</p>
<p>This interface is similar to the now-deprecated SAX 1.0
DocumentHandler interface, but it adds support for Namespaces
and for reporting skipped entities (in non-validating XML
processors).</p>
<p>Implementors should note that there is also a Java class
<CODE>ContentHandler</CODE> in the java.net
package; that means that it's probably a bad idea to do</p>
<blockquote>
import java.net.*;
import org.xml.sax.*;
</blockquote>
<p>In fact, "import ...*" is usually a sign of sloppy programming
anyway, so the user should consider this a feature rather than a
bug.</p>
