XML - can create but can't save
I wrote:
library(XML)
tt <- xmlHashTree()
head <- addNode(xmlNode("head"), character(), tt)
test <- addNode(xmlNode("test", attrs=c(pi="4")), head, tt)
tt # ok
saveXML(tt, file="test.xml") # error
I found a way to circumvent this error, by replacing the saveXML
line with:
sink("test.xml")
print(tt)
sink()
