<concept id="GUID-E6B3E575-80E3-58E3-9950-E0A5F6798861" xml:lang="en"><title> Using

the Parser Plug-in Resource File</title><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>This section explains how to specify the field values for a parser plug-in

resource file. </p>

<section><title>Procedure</title> <p>The XML framework is designed to manage

numerous parser implementations and has functionality to choose the implementation

most suited to the current document. </p> <p>The criteria used to make the

selection are held in 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. When this

information does not force the selection of exactly one parser, the framework

defaults firstly to choose a Symbian-supplied parser if present, else it will

choose the one with the lowest UID. When a parser implementation is created,

a resource file which supplies the related information must also be created. </p> <p>The <codeph>implementation_uid</codeph> field

must contain the <codeph>UID</codeph> of the plug-in. The <codeph>default_data</codeph> field

must contain the document type it can parse. The <codeph>opaque_data </codeph> field

specifies the supplier (Symbian or other). The following is a sample resource

file: </p> <codeblock id="GUID-2661506B-5B2F-50CF-A908-EAAE9B6EF726" xml:space="preserve">

RESOURCE REGISTRY_INFO validatorInfo

       {

       dll_uid = 0x10273863;

       interfaces = 

              {

              INTERFACE_INFO

                     {

                     interface_uid = 0x101FAA0B;

                     implementations = 

                            {

                            IMPLEMENTATION_INFO

                                   {

                                   implementation_uid = 0x10273864;

                                   version_no = 2;

                                   display_name = "Example parser";

                                   default_data = "text/xml||text/wbxml";

                                   opaque_data = "LicenseeX";

                                   }

                            };

                     }

              };
