Typical, I bang my head all afternoon, post, then it
finally dawns on me - I now have it sort of working.
However, could someone in the know tell me if this
is the "correct" approach ? I'm especially not
sure about the "node(0)" line.
public void setValueAt(Object o, int row, int col) {
Object object = definition.getRowXPath().selectNodes(source).get(row);
Iterator i =
((org.dom4j.tree.DefaultElement)object).elementIterator();
for ( Iterator iter = i; iter.hasNext(); )
{
Object oo = iter.next();
org.dom4j.Node n = ((org.dom4j.tree.DefaultElement)oo).node(0);
System.err.println(n);
n.setText(o.toString());
}
}
