Thanks a real lot Mike:
Thanks a lot for the detailed reply John:
After looking around enough, I think this is the best solution.
1. Parse the input XML as a DOM tree, using a validating parser.
2. Read or change the values as needed at this stage, on the resulting DOM tree.
3. Do the XSLT transformation and get the result as a DOM tree.
4. Read or change the values as needed at this stage, on the output DOM tree.
5. Serialize the tree into XML
Now my only concern is efficiency.
Another technique that occured to me is using JAXB..
1. Compile the input and output schemas into java object trees using JAXB.
2. Unmarshal the input XML to form the input side object tree.
3. Once input object tree is formed, change/read the values as required
4. Manually copy ( this step is equivalent to XSLT ) the values from the input
tree to form the output object tree.
5. Marshal the output tree to output XML.
Can anybody share their thoughts on this solution.
Thanks again

1. I have a java application that will be using XSLT, through the Java JAXP

We would like to make sure that both the input and output XMLs are in
aggreement to 2 respective schemas. Is it possible to do this using XSLT.
If possible are there any JAXP interfaces for this mechanism.
No, you don't do this using XSLT. You do it on the source document before
it is processed by XSLT, and on the result document after. You can use
JAXP, but how you use it will depend on the rest of your code.
2. While doing the above conversion, we would like to extract some
values from the input XML to a Java string variable. Similarly we would
like to
insert some values contained within the Java variables to the produced
XML. Is this possible at all.
Yes, certainly. However, this again sounds like a JAXP issue that is
independent of XSLT. You can use DOM, SAX, or whatever to retrieve values
from the source document and insert values into the result document.
