+<section id="GUID-3A5027A1-BEE9-5EB4-8670-7E729CF9260F"><title>Description</title> <p>The
+example application demonstrates, how to use the <xref href="GUID-54A442BD-FCF1-31D3-BEF7-598C1820F473.dita"><apiname>Xml</apiname></xref> framework
+to parse XML and WBXML files. It takes a valid XML file with a DTD (Document
+Type Declaration) definining its structure, and a WBXML (WAP Binary XML format)
+file as input. You can generate a WBXML file from an XML file using any freeware
+converters. The application's <filepath>bld.inf</filepath> file specifies
+the target path to which all the three files (XML, DTD, WBXML) need to be
+exported. </p> <p>The application implements all the pure virtual functions
+of the <xref href="GUID-54A442BD-FCF1-31D3-BEF7-598C1820F473.dita#GUID-54A442BD-FCF1-31D3-BEF7-598C1820F473/GUID-25E466A4-0578-3BED-A56D-4E0906313788"><apiname>Xml::MContentHandler</apiname></xref> class, which is a client interface
+to the <xref href="GUID-54A442BD-FCF1-31D3-BEF7-598C1820F473.dita"><apiname>Xml</apiname></xref> framework. These functions inform the client
+application about the XML element being parsed, its content, parser errors
+if any and so on. </p> <p>The XML and WBXML files are parsed using an object
+of the <xref href="GUID-54A442BD-FCF1-31D3-BEF7-598C1820F473.dita#GUID-54A442BD-FCF1-31D3-BEF7-598C1820F473/GUID-EE37CB28-DAB4-30A9-B46E-8AE4664B28DE"><apiname>Xml::CParser</apiname></xref> class. The parser object is configured
+to report namespace mappings to the client application, using the function <xref href="GUID-EE37CB28-DAB4-30A9-B46E-8AE4664B28DE.dita#GUID-EE37CB28-DAB4-30A9-B46E-8AE4664B28DE/GUID-5F2688CC-16B3-3F0D-B6CA-CE59FE7939BD"><apiname>Xml::CParser::EnableFeature()</apiname></xref>. </p> <p>The
+application first opens a file session using <xref href="GUID-E263C747-946F-35AA-9F1D-41833BD350FC.dita"><apiname>RFs</apiname></xref> to read
+the XML and WBXML files. Then, the <xref href="GUID-54A442BD-FCF1-31D3-BEF7-598C1820F473.dita#GUID-54A442BD-FCF1-31D3-BEF7-598C1820F473/GUID-CC810749-2F0D-3CC0-911D-EE12BB934867"><apiname>Xml::ParseL()</apiname></xref> function
+is called to start parsing the files. The application parses the XML file
+followed by the WBXML file. While these files are being parsed, status messages
+are printed to the console by the callback functions as and when they are
+invoked. </p> <p>For demonstration purposes, the XML file is parsed twice,
+once by the <xref href="GUID-54A442BD-FCF1-31D3-BEF7-598C1820F473.dita#GUID-54A442BD-FCF1-31D3-BEF7-598C1820F473/GUID-EE37CB28-DAB4-30A9-B46E-8AE4664B28DE"><apiname>Xml::CParser</apiname></xref> object created using the MIME
+type and again by the <codeph>CParser</codeph> object created using match
+data criteria. The match data criteria are specified using an object of the <xref href="GUID-54A442BD-FCF1-31D3-BEF7-598C1820F473.dita#GUID-54A442BD-FCF1-31D3-BEF7-598C1820F473/GUID-AEFF2DB4-FBC2-36EE-A4CE-7EBBD4AF004E"><apiname>Xml::CMatchData</apiname></xref> class,
+which is passed to the <xref href="GUID-EE37CB28-DAB4-30A9-B46E-8AE4664B28DE.dita#GUID-EE37CB28-DAB4-30A9-B46E-8AE4664B28DE/GUID-9E9D8DBA-A396-3F62-8B59-C4556FD5A80E"><apiname>Xml::CParser::NewLC()</apiname></xref> function while
+creating the parser object. This will return a <codeph>CParser</codeph> object
+that matches the specified MIME type, variant and so on. </p> </section>
