Question

I have a browser enabled infopath form with a dropdown box(cascaded), the data being retreived from an xml document. The data is in the following format-(as the value is retrieved from a lookup field.)

item_number;#item_value

how to show only the item_value in the dropdown box. Can I apply rules to the dropdown box or is there any way through code to achieve this?

Thanks for the help!

I found a similar post here cascaded dropdown look up field but there are no proper solutions

I found a solution but have trouble making it work,
I am using a file query connection to get the data for the dropdown, i will be executing the connection and populating an xml document with the result. I am having trouble writing the content to xmldocument, see my question here-

Infopath FileQueryConnection.Execute(XpathNavigator) throws System.Net.WebException: Attempted to read or write protected memory

I guess if this is solved, everything will be fine.

Finally found the solution:

 private void formatValue(string dataSourceName, string xPathSTring)
    {
        FileQueryConnection con = (FileQueryConnection)DataConnections[dataSourceName];
        con.Execute();
        DataSource ds = this.DataSources[dataSourceName];
        XPathNavigator nav = ds.CreateNavigator();
        XPathNavigator root = MainDataSource.CreateNavigator();
        XPathNodeIterator iterator = nav.Select(xPathSTring, NamespaceManager);
        while (iterator.MoveNext())
        {

            string value = iterator.Current.Value;
            int startFrom = value.IndexOf('#') + 1;
            iterator.Current.SetValue(value.Substring(startFrom, (value.Length - startFrom)));
        }
    }
