Pre-processing HL7 embedded in and XML message str

[[email protected]]

I have the following stream coming in and need to pre-process it in order to extract the HL7 message for processing.
<Doc>

<Payload>TVNIfF5+XCZ8UGFjZWFydHx8fHwyMDA2MDExODE1M TYyMjg0Mjg0MjJ8fEFDS15TMTJ8Yzc4NTNlN2UtYzI2MC00MTA 5LWIxODYtZGI0NGYxMGVhYTYzfFB8Mi4zfApNU0F8QUF8M2IxO TIzNTktZGIzZS00NWE4LWE2OWYtNzAwOTMzYmQ0N2IyfEFwcG9 pbnRtZW50SUQ6IDNiMTkyMzU5LWRiM2UtNDVhOC1hNjlmLTcwM DkzM2JkNDdiMiBoYXMgYmVlbiBhZGRlZCB0byB0aGUgUGF0aWV udHw=</Payload>

The HL7 message is in the base64 payload.

How do I get it out?
