Parsing of Mixed Content

[Sauquet Dominique]

Hi

It would be most helpful if you could provide me with Java Code samples to
parse Mixed Content such as :
                ....
            <prompt>
                I have <value expr="card_type"/>
                number <value expr="card_num"/>, 
                expiring on <value expr="expiry_date"/>.
                Is this correct?
            </prompt> 
                ...

If you do not have code samples, I would appreciate any idea of how to do
it.
Thanks a lot in advance
