I successfully query a service with the following code from here
\"username\", \"password\" => \"password\");
Try adding a ViewFields
parameter to your query. This allows you to specify which fields to return in the query and in what order.
viewFields is a child of the GetListItems
element:
<viewFields>
<ViewFields>
<FieldRef Name="LinkTitle" />
<FieldRef Name="Body" />
</ViewFields>
</viewFields>
Based on the example you gave, I'm guessing at the column names you'd be after; you may need to adjust to whatever SharePoint is actually calling those columns internally.
The ows_
prefix is added to the column name, so you wouldn't address them in that format except when retrieving from the result XML.
