Getting XML data in child node as string using JAXB

I am using JAXB to convert XML (parent XML, FIXML) to String. In this XML, one child node has another XML (child XML, FpML) data for which I had a schema (xsd). In the schema for parent XML, the type of element that has child XML is defined as String. I need child XML code that should appear as a string. Please let me know what change I need to make. I am relatively new to JAXB. Thanks at Advance .. !!

Cheers, Sakthi S
