Does anyone know how to write XML files in OO (but not using un-structured File System operations). I have specifically attempted to use groovy's MarkupBuilder but although it imports groovy.xml it cannot import groovy.xml.MarkupBuilder.
As far as I know there is no built in solution in OO.
I've never tried something like that but just a suggestion. Have you tried to use JSON format? You can constitute your xml data with JSON operations and after you can change it into XML form using XSLT transform operation. There are some solutions about transforming JSON to XML.
