Data Types in XML Data Source

[matthew.krohn]

I'm trying to create an XML data source that will be used to load a pallete of fields into reports. A simple example of this is:

<addressbook>
    <person>
        <name>
        <email/>
        <phone/>
    </person>
 </addressbook>

If I use an Xpath expression of  /addressbook/person this gets me the three fields I want, however all fields are defined as java.lang.String. How would I get phone for example, to be a data type other than String?
