\title{Create an XML node}
\description{
These functions allow one to create XML nodes
as are created in C code when reading XML documents.
Trees of XML nodes can be constructed and
integrated with other trees generated manually
or with via the parser.
}
\usage{
xmlNode(name, ..., attrs=NULL, namespace="")
xmlTextNode(value, namespace="")
xmlPINode(sys, value, namespace="")
xmlCDataNode(...)
xmlCommentNode(text)
}
\arguments{
\item{name}{The tag or element name of the XML node. This is what appears
in the elements as \code{<name> .. </name>}}
\item{\dots}{The children nodes of this XML node.
These can be objects of class \code{XMLNode}
or arbitrary values that will be converted to a string
to form an \code{XMLTextNode} object.}
\item{attrs}{A named character vector giving the
name, value pairs of attributes for this XML node.}
\item{value}{This is the text that is to be used when forming
an \code{XMLTextNode}.}
\item{namespace}{The XML namespace identifier for this node.}
\item{sys}{the name of the system for which the processing instruction
is targeted. This is the value that appears in the
\code{<?sys value?>}}
\item{text}{character string giving the contents of the comment.}
}
\value{
An object of class \code{XMLNode}.
In the case of \code{xmlTextNode},
this also inherits from \code{XMLTextNode}.
The fields or slots that objects
of these classes have
include
\code{name}, \code{attributes}, \code{children} and \code{namespace}.
However, one should
the accessor functions
\code{\link{xmlName}},
\code{\link{xmlAttrs}},
\code{\link{xmlChildren}}
and
\code{\link{xmlNamespace}}
