Hello, I am working with a database system from which I can retrieve these kinds of user defined fields formed as XML ...
<udf:field unit="uM" type="Numeric" name="facs.Stain final concentration">5</udf:field> You can see in the above example that "field" is defined in the namespace "udf", but that the "udf" namespace is not defined along with the attributes of the node. That is, 'xmlns:udf = "http://blah.blah.com/blah";' doesn't appear. I would like to create a similar node from scratch, but I can't seem to define the node with a namespace without providing the namespace definition. library(XML) node1 <- newXMLNode("storm", "ripsnorter", namespace = "weather", namespaceDefinitions = c(weather = "http://my.weather.com/events";), attrs = c(type = "hurricane", name = "Sandy")) node1 # this returns the new node with the namespace prefix (which I want) # and the definition (which I don't want) # <weather:storm xmlns:weather="http://my.weather.com/events"; type="hurricane" name="Sandy">ripsnorter</weather:storm> node2 <- newXMLNode("storm", "ripsnorter", namespace = "weather", attrs = c(type = "hurricane", name = "Sandy"), suppressNamespaceWarning = TRUE) node2 # produces the node without the namespace prefix and without the definition # <storm type="hurricane" name="Sandy">ripsnorter</storm> Is there some way to create a node with a namespace prefix but without embedding the namespace definition along with the attributes?
