\name{newXMLNamespace}
\alias{newXMLNamespace}
\title{Add a namespace definition to an XML node}
\description{
This function, and associated methods,
define a name space \code{prefix = URI} combination for the
given XML node.
It can also optionally make this name space the
default namespace for the node.
}
\usage{
newXMLNamespace(node, namespace, prefix = names(namespace), set = FALSE)
}
\arguments{
\item{node}{the XML node for which the name space is to be defined.}
\item{namespace}{the namespace(s).
This can be a simple character vector giving the URI,
a named character vector giving the prefix = URI pairs, with the prefixes being the names
of the character vector,
or one or more (a list) of \code{XMLNamespace} objects, e.g. returned from a call to
\code{\link{xmlNamespaceDefinitions}}}
\item{prefix}{
the prefixes to be associated with the URIs given in \code{namespace}.
}
\item{set}{ a logical value indicating whether to
set the namespace for this node to this newly created name space definition.
}
}
\value{
An name space definition object whose class corresponds
to the type of XML node given in \code{node}.
}
\note{
Currently, this only applies to XMLInternalNodes. This will be rectified shortly
and apply to RXMLNode and its non-abstract classes.
