XML encoding using R

Question

I have created an XML tree using the XML package in R, when saving using 'saveXML' the encoding argument is ignored.

here is an example

   xml1 <- xmlTree()
   xml1$addTag("Data","Hello World")

   saveXML(xml1,filepath, encoding = "UTF-8")

the result is as follows:

    <?xml version="1.0"?>
    <Data>Hello World</Data>

however I was expecting the top line to read:

    <?xml version="1.0" encoding="UTF-8"?>

any help would be appreciated

I was reading help on saveXML and it seems prefix attribute can be used to add that information. Try saveXML(xml1,filepath, prefix = '<?xml version="1.0" encoding="UTF-8"?>\n'). Please read help to understand the explanation. — Sagar

Maybe because UTF-8 is the default? stackoverflow.com/questions/16361909/… — Stefan Haustein

Typo? Your sample code says ecoding = "UTF-8" not encoding = "UTF-8" — G5W

The saveXML function has a prefix= parameter that you can use to set the header

saveXML(xml1, filepath, prefix='<?xml version="1.0" encoding="UTF-8"?>\n')
