XML Comparision - Urgent

[arunprabhu_k]

Hi,

Could anyone tell me how to compare two xml fragments in oracle 9i (in side a PLSQL block)?

For example,
if I have
XML1
====

<Text>
   <Element1 attrib1="XX">
   </Element1>
</Text>

XML2
====

<Text attrib1="">
    <Element1 attrib1="YY">
    </Element1>
</Text>

How to do a comparison between XML1 and XML2 in Oracle 9i?

Is there any predefined object to do this?

Please help me.

Thanks
Arun
