xml standalone property

[py-b]

Hello,
I can't find the way to add a standalone="yes" property in the xml_document.
Did I miss something in the package documentation?

Still interested by the answer, one year later...

It might help if you give a little more context with a simple example document you are trying to create.

This sort of question could also be a better fit for https://community.rstudio.com. Do you mind asking it over there? (You might want to read https://www.tidyverse.org/help/ first to maximise your chances of getting a good answer)

I am also wondering if one could add standalone=yes to the xml header, currently xml2 has only the option to add version and encoding:

> doc <- xml_new_document()
> as(doc, "character")
[1] "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"

When I am required to have:

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

I am not sure how one could update xml_new_document to keep its current output while making the standalone an option due to underlying C code in doc_new

xml_new_document <- function(version = "1.0", encoding = "UTF-8") {
  doc <- .Call(doc_new, version, encoding)
  out <- list(doc = doc)
  class(out) <- "xml_document"
  out
}
