Validating XML Document......

[Shravan Gunda <con_sgunda@xxxxxxxxxxx>]

Hi All,


Here is my XML and DTD files.

XML :

	<?xml version="1.0"?>
	<!DOCTYPE con_rloc_app SYSTEM "app.dtd">
	<application>
   		<PersonalInfo>
			   <MIName>N</MIName>
			   <LastName>Achem</LastName>
			   <Salutation>Mr.</Salutation>
			   <E-mail>abc@xxxxxxx</E-mail>
			   <JobTitle>jobtitle</JobTitle>
		   </PersonalInfo>
	</application>


DTD :

	<!ELEMENT application (PersonalInfo)>
        		<!ELEMENT PersonalInfo (FirstName, MIName?,
LastName, Salutation?, E-mail?,JobTitle)>
                		<!ELEMENT FirstName (#PCDATA)>
		            <!ELEMENT MIName (#PCDATA)>
		            <!ELEMENT LastName (#PCDATA)>
            		 <!ELEMENT Salutation (#PCDATA)>
		             <!ELEMENT E-mail (#PCDATA)>
		             <!ELEMENT JobTitle (#PCDATA)>

I am reading the xml file and passing it to DOMParser class. It is giving
the result as valid document.

My question here is , If i want make the FirstName as mandatory field what i
have to do in the dtd?
If the xml fiels doesnot contain FirstName, the parser should raise and
exception.

here is my code in the java class :

str1 contains the xml file.

		DOMParser xp = new DOMParser() ;
                  xp.setErrorHandler(err);
                  xp.parse(new InputSource(new StringReader(str1)));

Thanks,
Shravan.
