Message:

added a method for converting a nodelist to string - cos I needed it for debuggin purposes. plus a method for getting named elements based on more than one attribute. eg want all collectionmeta where name='dc.Title' and type='index' - we need to differentiate between index, sort, facet etc colleciton meta
