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><P><DL><DT><B>Since: </B><DD>SAX 2.0</DD><DT><B>Version: </B><DD>2.0r2pre</DD><DT><B>Author: </B><DD>David Megginson, <a href="mailto:sax@megginson.com">sax@megginson.com</a></DD><DT><B>See Also: </B><DD><A HREF="../../../org/xml/sax/XMLReader.html"><CODE>XMLReader</CODE></A>, <A HREF="../../../org/xml/sax/DTDHandler.html"><CODE>DTDHandler</CODE></A>, <A HREF="../../../org/xml/sax/ErrorHandler.html"><CODE>ErrorHandler</CODE></A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/xml/sax/ContentHandler.html#characters(char[], int, int)">characters</A></B>(char[] ch, int start, int length)</CODE><BR> Receive notification of character data.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/xml/sax/ContentHandler.html#endDocument()">endDocument</A></B>()</CODE><BR> Receive notification of the end of a document.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/xml/sax/ContentHandler.html#endElement(java.lang.String, java.lang.String, java.lang.String)">endElement</A></B>(java.lang.String namespaceURI, java.lang.String localName, java.lang.String qName)</CODE><BR> Receive notification of the end of an element.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/xml/sax/ContentHandler.html#endPrefixMapping(java.lang.String)">endPrefixMapping</A></B>(java.lang.String prefix)</CODE><BR> End the scope of a prefix-URI mapping.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/xml/sax/ContentHandler.html#ignorableWhitespace(char[], int, int)">ignorableWhitespace</A></B>(char[] ch, int start, int length)</CODE><BR> Receive notification of ignorable whitespace in element content.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/xml/sax/ContentHandler.html#processingInstruction(java.lang.String, java.lang.String)">processingInstruction</A></B>(java.lang.String target, java.lang.String data)</CODE><BR> Receive notification of a processing instruction.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/xml/sax/ContentHandler.html#setDocumentLocator(org.xml.sax.Locator)">setDocumentLocator</A></B>(<A HREF="../../../org/xml/sax/Locator.html">Locator</A> locator)</CODE><BR> Receive an object for locating the origin of SAX document events.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/xml/sax/ContentHandler.html#skippedEntity(java.lang.String)">skippedEntity</A></B>(java.lang.String name)</CODE><BR> Receive notification of a skipped entity.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/xml/sax/ContentHandler.html#startDocument()">startDocument</A></B>()</CODE>⌨️ 快捷键说明
