I have a Map (it can be nested map, containing of maps) and a schema. Keys in Map represent element/attribute name of the schema and an entry in Map will be at same depth as an element defined in schema

I need help in generating xml from the map as per the schema provided, without generating new files (as e.g Jaxb would require) Sample schema/map provided below

e.g Map = [dept=[deptno="10",dname="ABC",loc="XYZ",emps=[[empno=1000,ename="Albert"],[empno 00,ename="John"]]]] and schema will be

e.g Schema
<?xml version="1.0" encoding="windows-1252" ?>
<xsd:schema xmlns:xsd="" elementFormDefault="qualified">
   <xsd:element name="depts">
         <xsd:element name="dept" maxOccurs="unbounded">
               <xsd:element name="deptno" type="xsd:string"/><!-- This simple element e.g can be attribute in some schema-->
               <xsd:element name="dname" type="xsd:string"/>
               <xsd:element name="emps" maxOccurs="unbounded" minOccurs="0">
                     <xsd:element name="empno" type="xsd:string"/>
                     <xsd:element name="ename" type="xsd:string"/>

I would probably:
- generate a Java class from the schema (xjc)
- populate from Map to an instance of that class via recursion
   and reflection
- serialize instance to XML via JAXB

If you have high performance requirements, then you may need
to do some custom coding.
