<h2>Detailed Description</h2>
<p>The QXmlDTDHandler class provides an interface to report DTD content of XML data.</p>
<p>If an application needs information about notations and unparsed entities, it can implement this interface and register an instance with <a href="qxmlreader.html#setDTDHandler">QXmlReader::setDTDHandler</a>().</p>
<p>Note that this interface includes only those DTD events that the XML recommendation requires processors to report, i.e. notation and unparsed entity declarations using <a href="qxmldtdhandler.html#notationDecl">notationDecl</a>() and <a href="qxmldtdhandler.html#unparsedEntityDecl">unparsedEntityDecl</a>() respectively.</p>

<h3 class="fn"><a name="dtor.QXmlDTDHandler"></a>QXmlDTDHandler::<span class="name">~QXmlDTDHandler</span> ()<tt> [virtual]</tt></h3>

<h3 class="fn"><a name="errorString"></a><span class="type"><a href="qstring.html">QString</a></span> QXmlDTDHandler::<span class="name">errorString</span> () const<tt> [pure virtual]</tt></h3>
<p>The reader calls this function to get an error string if any of the handler functions returns false.</p>
<!-- @@@errorString -->
<!-- $$$notationDecl[overload1]$$$notationDeclconstQString&constQString&constQString& -->
<h3 class="fn"><a name="notationDecl"></a><span class="type">bool</span> QXmlDTDHandler::<span class="name">notationDecl</span> ( const <span class="type"><a href="qstring.html">QString</a></span> & <i>name</i>, const <span class="type"><a href="qstring.html">QString</a></span> & <i>publicId</i>, const <span class="type"><a href="qstring.html">QString</a></span> & <i>systemId</i> )<tt> [pure virtual]</tt></h3>
<p>The reader calls this function when it has parsed a notation declaration.</p>
<p>The argument <i>name</i> is the notation name, <i>publicId</i> is the notation's public identifier and <i>systemId</i> is the notation's system identifier.</p>
<p>If this function returns false the reader stops parsing and reports an error. The reader uses the function <a href="qxmldtdhandler.html#errorString">errorString</a>() to get the error message.</p>

<p>The reader calls this function when it finds an unparsed entity declaration.</p>
<p>The argument <i>name</i> is the unparsed entity's name, <i>publicId</i> is the entity's public identifier, <i>systemId</i> is the entity's system identifier and <i>notationName</i> is the name of the associated notation.</p>
<p>If this function returns false the reader stops parsing and reports an error. The reader uses the function <a href="qxmldtdhandler.html#errorString">errorString</a>() to get the error message.</p>
