The TQXmlDeclHandler class provides an interface to report declaration
content of XML data.

<p> 

<p> You can set the declaration handler with
<a href="qxmlreader.html#setDeclHandler">TQXmlReader::setDeclHandler</a>().
<p> This interface is based on the SAX2 extension DeclHandler.
<p> The interface provides <a href="#attributeDecl">attributeDecl</a>(), <a href="#internalEntityDecl">internalEntityDecl</a>() and
<a href="#externalEntityDecl">externalEntityDecl</a>() functions.
<p> See also the <a href="xml.html#sax2Intro">Introduction to SAX2</a>.
<p> <p>See also <a href="qxmldtdhandler.html">TQXmlDTDHandler</a>, <a href="qxmlcontenthandler.html">TQXmlContentHandler</a>, <a href="qxmlentityresolver.html">TQXmlEntityResolver</a>, <a href="qxmlerrorhandler.html">TQXmlErrorHandler</a>, <a href="qxmllexicalhandler.html">TQXmlLexicalHandler</a>, and <a href="xml-tools.html">XML</a>.

<h3 class=fn>bool <a name="attributeDecl"></a>TQXmlDeclHandler::attributeDecl ( const&nbsp;<a href="ntqstring.html">TQString</a>&nbsp;&amp;&nbsp;eName, const&nbsp;<a href="ntqstring.html">TQString</a>&nbsp;&amp;&nbsp;aName, const&nbsp;<a href="ntqstring.html">TQString</a>&nbsp;&amp;&nbsp;type, const&nbsp;<a href="ntqstring.html">TQString</a>&nbsp;&amp;&nbsp;valueDefault, const&nbsp;<a href="ntqstring.html">TQString</a>&nbsp;&amp;&nbsp;value )<tt> [pure virtual]</tt>
</h3>

<p> The reader calls this function to report an attribute type
declaration. Only the effective (first) declaration for an
attribute is reported.
<p> The reader passes the name of the associated element in <em>eName</em>
and the name of the attribute in <em>aName</em>. It passes a string that
represents the attribute type in <em>type</em> and a string that
represents the attribute default in <em>valueDefault</em>. This string
is one of "#IMPLIED", "#REQUIRED", "#FIXED" or <a href="ntqstring.html#TQString-null">TQString::null</a> (if
none of the others applies). The reader passes the attribute's
default value in <em>value</em>. If no default value is specified in the
XML file, <em>value</em> is TQString::null.
<p> If this function returns FALSE the reader stops parsing and
reports an error. The reader uses the function <a href="#errorString">errorString</a>() to
get the error message.

<h3 class=fn><a href="ntqstring.html">TQString</a> <a name="errorString"></a>TQXmlDeclHandler::errorString ()<tt> [pure virtual]</tt>
</h3>

<p> The reader calls this function to get an error string if any of
the handler functions returns FALSE.

<h3 class=fn>bool <a name="externalEntityDecl"></a>TQXmlDeclHandler::externalEntityDecl ( const&nbsp;<a href="ntqstring.html">TQString</a>&nbsp;&amp;&nbsp;name, const&nbsp;<a href="ntqstring.html">TQString</a>&nbsp;&amp;&nbsp;publicId, const&nbsp;<a href="ntqstring.html">TQString</a>&nbsp;&amp;&nbsp;systemId )<tt> [pure virtual]</tt>
</h3>

<p> The reader calls this function to report a parsed external entity
declaration. Only the effective (first) declaration for each
entity is reported.
<p> The reader passes the name of the entity in <em>name</em>, the public
identifier in <em>publicId</em> and the system identifier in <em>systemId</em>. If there is no public identifier specified, it passes
<a href="ntqstring.html#TQString-null">TQString::null</a> in <em>publicId</em>.
<p> If this function returns FALSE the reader stops parsing and
reports an error. The reader uses the function <a href="#errorString">errorString</a>() to
get the error message.

<h3 class=fn>bool <a name="internalEntityDecl"></a>TQXmlDeclHandler::internalEntityDecl ( const&nbsp;<a href="ntqstring.html">TQString</a>&nbsp;&amp;&nbsp;name, const&nbsp;<a href="ntqstring.html">TQString</a>&nbsp;&amp;&nbsp;value )<tt> [pure virtual]</tt>
</h3>

<p> The reader calls this function to report an internal entity
declaration. Only the effective (first) declaration is reported.
<p> The reader passes the name of the entity in <em>name</em> and the value
of the entity in <em>value</em>.
<p> If this function returns FALSE the reader stops parsing and
reports an error. The reader uses the function <a href="#errorString">errorString</a>() to
get the error message.
