Having an empty node is not sufficient? Note that when you delete something from the DOM that a remerge of the data and template will happen automatically ...this has caused me grief in the past (if you are getting additional data from an external source).

The command is:

xfa.datasets.data.form1.page1.nodes.remove(xfaObject to remove);

so typically the exppression is like this:

xfa.datasets.data.form1.page1.nodes.remove(xfa.resolveNode("xfa.datasets.data.form1.page1.billingMailAddr"));

Assuming you wanted to remove the billingMailAddr nodes.
