I currently have this XML.

<response success="true" error="">

    <PropertySet Name="IX_DOCUMENT" Caption="Document Additional Meta Data" AppliesToDocuments="TRUE" AppliesToFolders="FALSE" AppliesToUsers="FALSE" SystemUseOnly="FALSE">

        <DomainRestrictions Global="TRUE"/>

        <Fields>

            <field FieldName="BARCODE" Caption="Barcode" DataType="CHAR" DataLength="50" Required="FALSE" ControlSize="50" ControlOrder="1" ControlType="TEXT BOX"/>

            <field FieldName="BOX_NUMBER" Caption="Box Number" DataType="CHAR" DataLength="16" Required="FALSE" ControlSize="16" ControlOrder="2" ControlType="TEXT BOX"/>

        </Fields>

    </PropertySet>

</response>

This is returned to me as XmlElement. I am having trouble writing some code that will check the grandchildren 'fields' for the 'FieldName' attribute. I need to return true if it can find a field with FieldName as BARCODE and a FieldName as BOX_NUMBER. Not sure if this helps at all but the code that I use to retrieve this is;

XmlElement XmlResponse = (XmlElement)IR_OBJ.GetPropertySetDefinition(ticket, "IX_DOCUMENT");

Any help is appreciated.

EDIT: Put XML in Code
