documentToXMLString from Java service

Hi,

I’m updating an existing Java service that takes either an XML Node or Document as an argument for processing and now need to convert it to a string.

I know that this can be done by using a Service.doInvoke to one of the documentToXMLString (and potentially other XML services) but wondered if it was possibly to serialise the Node/Document Java objects directly in code?

Many thanks,
