Hello,
With help from these forums I finally learned how to script creating a parent xml element from a selection in the Structure Pane.
var myDoc = app.activeDocument;
var mySel = app.selection;
var newParent = myDoc.xmlElements[0].xmlElements.add({markupTag:"c_bullet_list"}).move(LocationOptions.before, mySel[0]);
var i = mySel.length;
while(i--){
mySel[i].move(LocationOptions.AT_BEGINNING, newParent);
}
Hope this helps somebody.
