Hi,

I will have files like:

<get>
    <filter>
        <configure xmlns="urn:nokia.com:sros:ns:yang:sr:conf">
            <system>
                <security>
                    <user-params>
                        <local-user>
                            <user>
                                <user-name />  <!-- selection node in context A -->
                            </user>
                        </local-user>
                    </user-params>
                </security>
            </system>
        </configure>
        <state xmlns="urn:nokia.com:sros:ns:yang:sr:state">
            <system>
                <security>
                    <user-params>
                        <local-user>
                            <user>
                                <attempted-logins />  <!-- selection node in context B -->
                            </user>
                        </local-user>
                    </user-params>
                </security>
            </system>
        </state>
    </filter>
</get>

I will need to parse to xml:

 <configure xmlns="urn:nokia.com:sros:ns:yang:sr:conf">
            <system>
                <security>
                    <user-params>
                        <local-user>
                            <user>
                                <user-name />  <!-- selection node in context A -->
                            </user>
                        </local-user>
                    </user-params>
                </security>
            </system>
        </configure>
        <state xmlns="urn:nokia.com:sros:ns:yang:sr:state">
            <system>
                <security>
                    <user-params>
                        <local-user>
                            <user>
                                <attempted-logins />  <!-- selection node in context B -->
                            </user>
                        </local-user>
                    </user-params>
                </security>
            </system>
        </state>

However it is not valid xml since it is two roots. How can I detect that I have two roots. Currently I am only seeing this when parse fails ( see below) And message is too general to know there are multiple ( in this case 2) roots.
If I can detect multi roots I can split string and parse each and add them together later ( I think).

Any ideas?
br,
