But how big is it, and what does it look like? (I assume it's all
printable ASCII, since you're getting it as the output of a shell command)
If it's *really* large, possibly it would go better as a subelement of
<interface>, rather than an attribute, i.e.:
<interface index='1' vporttype='openvswitch'>
<portdata>
blah blah blah blah
</portdata>
</interface>
