    Have a look at the following process: 

    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
    <process version="6.0.009">
      <context>
        <input/>
        <output/>
        <macros/>

      <operator activated="true" class="process" compatibility="6.0.009" expanded="true" name="Process">
        <process expanded="true">
          <operator activated="true" class="retrieve" compatibility="6.0.009" expanded="true" height="60" name="Retrieve Iris" width="90" x="45" y="30">
            <parameter key="repository_entry" value="//Samples/data/Iris"/>
          </operator>
          <operator activated="true" class="loop_attributes" compatibility="6.0.009" expanded="true" height="76" name="Loop Attributes" width="90" x="179" y="30">

                <list key="function_descriptions">
                  <parameter key="name" value="concat(&quot;%{loop_attribute}&quot;, &quot;_0&quot;)"/>
                </list>
              </operator>
              <operator activated="true" class="rename" compatibility="6.0.009" expanded="true" height="76" name="Rename" width="90" x="246" y="30">
                <parameter key="old_name" value="%{loop_attribute}"/>
                <parameter key="new_name" value="%{name}"/>
                <list key="rename_additional_attributes"/>
              </operator>
              <connect from_port="example set" to_op="Generate Macro" to_port="through 1"/>
              <connect from_op="Generate Macro" from_port="through 1" to_op="Rename" to_port="example set input"/>

            </process>
          </operator>
          <connect from_op="Retrieve Iris" from_port="output" to_op="Loop Attributes" to_port="example set"/>
          <connect from_op="Loop Attributes" from_port="example set" to_port="result 1"/>

          <portSpacing port="sink_result 1" spacing="0"/>
