XML Stack Overflow

the objective is to flatten a multilevel repeated xml into xpaths at a leaf level ; so that we can store it in a store and retrieve it

1. generate a list of pairs where the Key is a "XPATH" and Values are the actual value of that leaf


2. Should be able to assemble it back into an xml


3. the xml is backed by an xsd ( is there a JAXB solution )

a sample xml looks like below

<?xml version="1.0" encoding="UTF-8"?>
<cars>
    <regInfo>
        <regName>car</regName>
        <regCreationInfo>
            <regCreationDate>2001-10-31T08:15:00.000z</regCreationDate>
            <regCreator>Joe Smith</regCreator>
        </regCreationInfo>
    </regInfo>
