$tmpVar - input source varaible',' - delimiter string'chunk' - the target XML element
Suppose initial value of tmpVar is
<unit:split><TestPart>1,2,3,4</TestPart></unit:split>
After executing split-to-elements() the value of myVar is
<TestPartxmlns:unit="http://ode/bpel/unit-test.wsdl"><chunk>1</chunk><chunk>2</chunk><chunk>3</chunk><chunk>4</chunk></TestPart>
