\name{setXMLNamespace}
\alias{setXMLNamespace}
\title{Set the name space on a node}
\description{
This function sets the name space for an XML node, typically
an internal node. We can use it to either define a new namespace
and use that, or refer to a name space definition in an ancestor
of the current node.
}
\usage{
setXMLNamespace(node, namespace, append = FALSE)
}
\arguments{
\item{node}{the node on which the name space is to be set}
\item{namespace}{the name space to use for the node. This can be a
name space prefix (string) defined in an ancestor node, or a named
character vector of the form \code{c(prefix = URI)} that defines a
new namespace on this node, or we can use a name space object
created with \code{\link{newXMLNamespace}}.}
\item{append}{currently ignored.}
}
\value{
An object of class \code{XMLNamespaceRef} which is a reference to the
native/internal/C-level name space object.
