illegal XML element .......but no error why?

[Harish Tiruvile]

Hi all,

We are using DTD to define legal elements in XML file...that means if we add illegal elements it should indicate error.

But in the following example...while declaring elements in DTD i have mentioned that in xml file both fname and lname should present in any order...so


**********************************************************************
File:Test.dtd

<!ELEMENT Name ((fname,lname)|(lname,fname))>
<!ELEMENT lname (#PCDATA)>
<!ELEMENT fname (#PCDATA)>
<!ENTITY initial "Tiruvile">

**********************************************************************

File:XmlTest.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE node SYSTEM "test.dtd">
<Name>
     <fname>Harish. &initial;</fname>[B]//Note::I have not included lname[/B]
</Name>

**********************************************************************
Ouput from internet explore version 6.0

 <?xml version="1.0" encoding="UTF-8" ?> 
  <!DOCTYPE node (View Source for full doctype...)> 
- <Name>
  <fname>Harish. Tiruvile</fname> 
  </Name>

**********************************************************************

As per declaration i should get error because i have not included lname in XML file...but i am not getting error Why?

I have altered Name element declaration as follows ,still i am not getting error

<!ELEMENT Name (fname+,lname+)>
<!ELEMENT Name ((fname,lname)|(fname,lname))+>

if it is not giving Error then what is the use of DTD...i mean how it is restricting the applications from entering illegal elements in to xml file

If anybody knows please tell me the reason...

So you are asking about the XML parser built into IE 6.0? Looks like it's a non-validating parser.
