iterate mediator need a list of xml nodes so, create a new XML message with the list of values extracted from your property 'MessageText' (the purpose of script mediator) and then, iterate the nodes from this message with iterate mediator
<inSequence>
<property name="MessageText" value="a,b,c" scope="default"/>
<script language="js"><![CDATA[
var payloadXML = new XML(<root/>);
for each (var item in String(mc.getProperty("MessageText")).split(',')) {
payloadXML.appendChild(new XML(<item>{item}</item>));
}
mc.setPayloadXML(payloadXML);
]]></script>
<iterate xmlns:fn="http://www.w3.org/2005/xpath-functions" continueParent="true" expression="//item" sequential="true">
<target>
<sequence>
<log level="full" separator=",">
<property name="arrayChar" expression="$body/item"></property>
</log>
</sequence>
</target>
</iterate>
</inSequence>
