Hello,
I'd like to convert R data frames into xml-trees. I wrote (and copied)
this little program to do this:
convertToXML <- function(df,name)
{
xml <- xmlTree("Test")
xml$addNode(name, close=FALSE)
for (i in 1:nrow(df)) {
xml$addNode("value", close=FALSE)
for (j in names(df)) {
xml$addNode(j, df[i, j])
}
xml$closeTag()
}
xml$closeTag()
return(xml)
}
Well, now I get a warning message like
"In xmlRoot.XMLInternalDocument(currentNodes[[1]]) : empty XML document"
if I use this function. How could this be fixed?
Thank you for your help!
Tom
