In our project we need to have a select box which lets the user choose among a list of items coming from an external data source (XML based webservice). It would be interesting to be able to retrieve the values of a CCK field from an external data source instead to "hardcode" the full list of values. A way to do it could be to specify, in the field setting, the XML end point and an xPath expression to map the values contained in the XML as values of the CCK field.
Any feedback on this?
