Set the name space on a node

setXMLNamespace.Rd

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

node

the node on which the name space is to be set

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 c(prefix = URI) that defines a new namespace on this node, or we can use a name space object created with newXMLNamespace.

append

currently ignored.

Value

An object of class XMLNamespaceRef which is a reference to the native/internal/C-level name space object.
