converting XQuery results to Java objects generated by XmlBeans

[Alec Lebedev <al...@nextpage.com>]

XmlObject.execQuery() returns an array of XmlObjects. But how do I
convert this array to an array of classes generated by XmlBeans?

 

Thanks.

It turns out that execQuery returns an array of XmlBeans-generated class
only if there is an XSD <element> declared for the elements returned by
execQuery. It is not sufficient just to have an XSD type defined for
those elements. Consider the following XSD and XML:

 

XSD: 

 

<schema ...>

<complexType name="RootDefinition">

                        <sequence>

                                    <element name="dataSource"
type="tns:DataSource" minOccurs="1" maxOccurs="unbounded"></element>

                        </sequence>

            </complexType>

 

<complexType name="DataSource">

                        <attribute name="name" type="ID"
use="required"></attribute>

            </complexType>

 

            <element name="definition"
type="tns:RootDefinition"></element>

            <!--<element name="dataSource"
type="tns:DataSource"></element>-->

</schema>

 

XML:

 

<definition ..>

            <dataSource name="ds-live"/>

</definition>

 

The following query will return XmlObject[] with the dataSource element
commented out in XSD and will return DataSourceDocument[] when
dataSource is un-commented in the XSD.

XQuery:

"for $x in .//xq:definition/xq:dataSource return $x"

 

I don't understand why I have to have the element definition (in
addition to the type definition) in the XSD for XmlBeans to properly
cast the result of the query?

 

Thanks.
