Renaming segments

[rvoith610]

Mirth 4.5.2

I have an ORU messages with several OBX segments from a medical device. Some of those OBXs represent the clinical data and others the medical device details. I'm looking to rename the segments which present as medical devices.
I can set the name on the obx with setLocalName('DEV') however that will only update the "parent" of the OBX.
Looking at the underlying xml...

From

 <DEV>
        <OBX.1>
            <OBX.1.1>1</OBX.1.1>
        </OBX.1>
        <OBX.2/>
        <OBX.3>
            <OBX.3.1>1111</OBX.3.1>
            <OBX.3.2>SAT_O2_MDS</OBX.3.2>
            <OBX.3.3>MDC</OBX.3.3>
        </OBX.3>
        <OBX.4>
            <OBX.4.1>1</OBX.4.1>
        </OBX.4>
        <OBX.5>
            <OBX.5.1>1</OBX.5.1>
        </OBX.5>
        <OBX.5>
            <OBX.5.1>2</OBX.5.1>
            <OBX.5.2>
                <OBX.5.2.1>2</OBX.5.2.1>
                <OBX.5.2.2>2</OBX.5.2.2>
            </OBX.5.2>
        </OBX.5>...

To:

 <DEV>
        <DEV.1>
            <DEV.1.1>1</DEV.1.1>
        </DEV.1>
        <DEV.2/>
        <DEV.3>
            <DEV.3.1>1111</DEV.3.1>
            <DEV.3.2>SAT_O2_MDS</DEV.3.2>
            <DEV.3.3>MDC</DEV.3.3>
        </DEV.3>
        <DEV.4>
            <DEV.4.1>1</DEV.4.1>
        </DEV.4>
      ...

I want to update all it's nested children.
What's the best way to do this? Or would it just be easier to create a new segment, and copy what I want from OBX to DEV?
Thanks
