|
|
|
|
|
|
|
|
The TQXmlLexicalHandler class provides an interface to
|
|
report the lexical content of XML data.
|
|
|
|
<p>
|
|
|
|
<p> The events in the lexical handler apply to the entire document,
|
|
not just to the document element, and all lexical handler events
|
|
appear between the content handler's startDocument and endDocument
|
|
events.
|
|
<p> You can set the lexical handler with
|
|
<a href="tqxmlreader.html#setLexicalHandler">TQXmlReader::setLexicalHandler</a>().
|
|
<p> This interface's design is based on the the SAX2 extension
|
|
LexicalHandler.
|
|
<p> The interface provides the <a href="#startDTD">startDTD</a>(), <a href="#endDTD">endDTD</a>(), <a href="#startEntity">startEntity</a>(),
|
|
<a href="#endEntity">endEntity</a>(), <a href="#startCDATA">startCDATA</a>(), <a href="#endCDATA">endCDATA</a>() and <a href="#comment">comment</a>() functions.
|
|
<p> See also the <a href="xml.html#sax2Intro">Introduction to SAX2</a>.
|
|
<p> <p>See also <a href="tqxmldtdhandler.html">TQXmlDTDHandler</a>, <a href="tqxmldeclhandler.html">TQXmlDeclHandler</a>, <a href="tqxmlcontenthandler.html">TQXmlContentHandler</a>, <a href="tqxmlentityresolver.html">TQXmlEntityResolver</a>, <a href="tqxmlerrorhandler.html">TQXmlErrorHandler</a>, and <a href="xml-tools.html">XML</a>.

<h3 class=fn>bool <a name="comment"></a>TQXmlLexicalHandler::comment ( const <a href="tqstring.html">TQString</a> & ch )<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> The reader calls this function to report an XML comment anywhere
|
|
in the document. It reports the text of the comment in <em>ch</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="endCDATA"></a>TQXmlLexicalHandler::endCDATA ()<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> The reader calls this function to report the end of a CDATA
|
|
section.
|
|
<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.
|
|
<p> <p>See also <a href="#startCDATA">startCDATA</a>() and <a href="tqxmlcontenthandler.html#characters">TQXmlContentHandler::characters</a>().
|
|
|
|
<h3 class=fn>bool <a name="endDTD"></a>TQXmlLexicalHandler::endDTD ()<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> The reader calls this function to report the end of a DTD
|
|
declaration, if any.
|
|
<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.
|
|
<p> <p>See also <a href="#startDTD">startDTD</a>().
|
|
|
|
<h3 class=fn>bool <a name="endEntity"></a>TQXmlLexicalHandler::endEntity ( const <a href="tqstring.html">TQString</a> & name )<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> The reader calls this function to report the end of an entity
|
|
called <em>name</em>.
|
|
<p> For every <a href="#startEntity">startEntity</a>() call, there is a corresponding <a href="#endEntity">endEntity</a>()
|
|
call. The calls to startEntity() and endEntity() are properly
|
|
nested.
|
|
<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.
|
|
<p> <p>See also <a href="#startEntity">startEntity</a>(), <a href="tqxmlcontenthandler.html#skippedEntity">TQXmlContentHandler::skippedEntity</a>(), and <a href="tqxmlsimplereader.html#setFeature">TQXmlSimpleReader::setFeature</a>().

|
|
<h3 class=fn><a href="tqstring.html">TQString</a> <a name="errorString"></a>TQXmlLexicalHandler::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="startCDATA"></a>TQXmlLexicalHandler::startCDATA ()<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> The reader calls this function to report the start of a CDATA
|
|
section. The content of the CDATA section is reported through the
|
|
<a href="tqxmlcontenthandler.html#characters">TQXmlContentHandler::characters</a>() function. This function is
|
|
intended only to report the boundary.
|
|
<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.
|
|
<p> <p>See also <a href="#endCDATA">endCDATA</a>().
|
|
|

<h3 class=fn>bool <a name="startDTD"></a>TQXmlLexicalHandler::startDTD ( const <a href="tqstring.html">TQString</a> & name, const <a href="tqstring.html">TQString</a> & publicId, const <a href="tqstring.html">TQString</a> & systemId )<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> The reader calls this function to report the start of a DTD
|
|
declaration, if any. It reports the name of the document type in
|
|
<em>name</em>, the public identifier in <em>publicId</em> and the system
|
|
identifier in <em>systemId</em>.
|
|
<p> If the public identifier is missing, <em>publicId</em> is set to
|
|
<a href="tqstring.html#TQString-null">TQString::null</a>. If the system identifier is missing, <em>systemId</em> is
|
|
set to TQString::null. Note that it is not valid XML to have a
|
|
public identifier but no system identifier; in such cases a parse
|
|
error will occur.
|
|
<p> All declarations reported through <a href="tqxmldtdhandler.html">TQXmlDTDHandler</a> or
|
|
<a href="tqxmldeclhandler.html">TQXmlDeclHandler</a> appear between the <a href="#startDTD">startDTD</a>() and <a href="#endDTD">endDTD</a>() calls.
|
|
<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.
|
|
<p> <p>See also <a href="#endDTD">endDTD</a>().
|
|
|

<h3 class=fn>bool <a name="startEntity"></a>TQXmlLexicalHandler::startEntity ( const <a href="tqstring.html">TQString</a> & name )<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> The reader calls this function to report the start of an entity
|
|
called <em>name</em>.
|
|
<p> Note that if the entity is unknown, the reader reports it through
|
|
<a href="tqxmlcontenthandler.html#skippedEntity">TQXmlContentHandler::skippedEntity</a>() and not through this
|
|
function.
|
|
<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.
|
|
<p> <p>See also <a href="#endEntity">endEntity</a>() and <a href="tqxmlsimplereader.html#setFeature">TQXmlSimpleReader::setFeature</a>().
