This function is a XPath extension supported by the Apache ODE engine ( http://ode.apache.org/xpath-extensions.html) which can be used to generate arrays from a string.
The method accept four input parameters as follows.
split-to-elements(stringToSplit, separator, targetElement, targetNamespace)
eg -
split-to-elements($input, '123', 'chunk', 'http://ode/bpel/unit-test.wsdl')
if $input is -
<unit:split> <TestPart>hello123bill123smith</TestPart> </unit:split>
output will be some thing as follows -
<TestPart xmlns:unit="http://ode/bpel/unit-test.wsdl"> <chunk xmlns="http://ode/bpel/unit-test.wsdl">hello</chunk> <chunk xmlns="http://ode/bpel/unit-test.wsdl">bill</chunk> <chunk xmlns="http://ode/bpel/unit-test.wsdl">smith</chunk> </TestPart>
Note - split-to-elements() method should be used under the namespace of "http://www.apache.org/ode/type/extension"
<copy> <from>ode:split-to-elements($tmpVar, ',', 'chunk')</from> <to variable="myVar" part="TestPart"/> </copy>
This method accept three parameters as follows.
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
<TestPart xmlns:unit="http://ode/bpel/unit-test.wsdl"> <chunk>1</chunk> <chunk>2</chunk> <chunk>3</chunk> <chunk>4</chunk> </TestPart>
