linking and DOM

["Yallala, Bhaskar" <B_Yallala@DirectAdvice.com>]

Hi
           Example: 
	I have a.xml , which has DateInterval 
like,
	<Date Interval>
		<start><Date>xyz</Date></<start>
		<limit><Date>pqr</Date></<limit>
	</Date Interval>

And I have another file called b.xml, in which Date with ID= xyz is present.

How can I parse this using DOM and how can I refer in a.xml , how to goto
b.xml's xyz ID?


Yours sincerely,
Bhaskar Yallala
