Re: [jibx-users] Unmarshalling attributes of child element to a collection

[Darin C. <DC...@pd...>]

You might try something like

<collection create-type=”java.util.ArrayList” field=”childElems”>
<structure name=”ChildElem”><value name=”ChildElemValue” style=”attribute” type=”java.lang.String”/></structure>
</collection>

That is, the collection has no name, in particular, but is composed of a bunch of ‘ChildElem’ elements.  The ‘ChildElem’ elements, themselves, don’t have any special binding to an object, but are just structural XML, containing an attribute named “ChildElemValue” which is a String.

Not absolutely sure this will work right, but it might.

Subject: [jibx-users] Unmarshalling attributes of child element to a collection

​Hello,

​
​I am trying to use JiBX to parse a larger XML, which includes a structure similar to the ones noted below:

Schema:
<xs:complexType name="Parent">
    <xs:sequence>
        <xs:element name="ChildElem" maxOccurs="unbounded">
            <xs:complexType>
                <xs:attribute name="ChildElemValue" type="xs:string" use="required"/>
            </xs:complexType>
        </xs:element>
    </xs:sequence>
    <xs:attribute name="Child1" type="xs:string"/>
    <xs:attribute name="Child2" type="xs:int"/>
</xs:complexType>
Sample Value:
<Parent Child1="AttrVal" Child2="999">
    <ChildElem ChildElemValue="SomeVal"/>
    <ChildElem ChildElemValue="SomeVal2"/>
</Parent>​

The equivalent class I am trying to map this to is:
public class Parent {
    private String child1;
    private int Child2;
    private List<String> childElems;
}
I am trying to write a mapping for marshalling and unmarshalling, without requiring a class to represent the ChildElem, because all it will ever have is a string in the ChildElemValue attribute.
I am open to (but not experienced with) custom Marshaller / Unmarshaller, and if so, I would like to reuse them as much as possible, as there are similar structures as above (with different element / attribute names) all over the project.

Any help or direction in accomplishing this would be greatly appreciated.

Regards,
Bindul​
