Examples

tree = newXMLDoc()

newXMLNode("xmcda:XMCDA", 
           namespace = c("xsi" = "http://www.w3.org/2001/XMLSchema-instance", 
           "xmcda" = "http://www.decision-deck.org/2009/XMCDA-2.0.0"), 
           parent=tree)

root<-getNodeSet(tree, "/xmcda:XMCDA")

parameters<-newXMLNode("methodParameters", parent=root[[1]], namespace=c())

parameter <- newXMLNode("parameter",attrs = c(name="numIt"), 
                        parent=parameters, namespace=c())

value <- newXMLNode("value", parent=parameter, namespace=c())

newXMLNode("integer", value=3, parent=value, namespace=c())
