If you are using the declaration handler together with a lexical handler, all of the events will occur between the startDTD and the endDTD events. To set the <a href="Poco.XML.DeclHandler.html" title="class Poco::XML::DeclHandler">DeclHandler</a> for an <a href="Poco.XML.html" title="namespace Poco::XML">XML</a> reader, use the setProperty method with the propertyId "<a href="http://xml.org/sax/properties/declaration-handler"" target="_blank">http://xml.org/sax/properties/declaration-handler"</a>. If the reader does not support declaration events, it will throw a <a href="Poco.XML.SAXNotRecognizedException.html" title="class Poco::XML::SAXNotRecognizedException">SAXNotRecognizedException</a> or a <a href="Poco.XML.SAXNotSupportedException.html" title="class Poco::XML::SAXNotSupportedException">SAXNotSupportedException</a> when you attempt to register the handler. </p> </div> <h2>Member Summary</h2> <p><b>Member Functions: </b><a href="Poco.XML.DeclHandler.html#18896" title="Poco::XML::DeclHandler::attributeDecl()">attributeDecl</a>, <a href="Poco.XML.DeclHandler.html#18901" title="Poco::XML::DeclHandler::elementDecl()">elementDecl</a>, <a href="Poco.XML.DeclHandler.html#18904" title="Poco::XML::DeclHandler::externalEntityDecl()">externalEntityDecl</a>, <a href="Poco.XML.DeclHandler.html#18908" title="Poco::XML::DeclHandler::internalEntityDecl()">internalEntityDecl</a></p> <h2>Destructor</h2> <h3><a name="18911">~DeclHandler</a> <img src="images/protected.gif" alt="protected" title="protected" style="vertical-align:baseline;" border="0" /> <img src="images/virtual.gif" alt="virtual" title="virtual" style="vertical-align:baseline;" border="0" /> </h3> <p class="decl">virtual ~<a href="Poco.XML.DeclHandler.html" title="class Poco::XML::DeclHandler">DeclHandler</a>();</p> <div class="description"> <p></p> </div> <h2>Member Functions</h2> <h3><a name="18896">attributeDecl</a> <img src="images/virtual.gif" alt="virtual" title="virtual" style="vertical-align:baseline;" border="0" /> </h3> <p class="decl">virtual void attributeDecl(<br /> const <a href="Poco.XML.html#19841" title="Poco::XML::XMLString">XMLString</a> & eName,<br /> const <a href="Poco.XML.html#19841" title="Poco::XML::XMLString">XMLString</a> & aName,<br /> const <a href="Poco.XML.html#19841" title="Poco::XML::XMLString">XMLString</a> * valueDefault,<br /> const <a href="Poco.XML.html#19841" title="Poco::XML::XMLString">XMLString</a> * value<br />) = 0;</p> <div class="description"> <p>Report an attribute type declaration. </p> <p>Only the effective (first) declaration for an attribute will be reported.
