\title{ Gets the sub-nodes within an XMLNode object. }
\description{
These functions provide access to the children of the given
XML node.
The simple accessor returns a list of child XMLNode objects within an
XMLNode object.
The assignment operator (\code{xmlChildren<-}) sets the
children of the node to the given value and returns the
updated/modified node. No checking is currently done
on the type and values of the right hand side. This allows
the children of the node to be arbitrary R objects. This can
be useful but means that one cannot rely on any structure in a node
being present..
}
\usage{
xmlChildren(x, addNames= TRUE, ...)
}
\arguments{
\item{x}{an object of class XMLNode.}
\item{addNames}{a logical value indicating whether to add the XML
names of the nodes as names of the R list.
This is only relevant for XMLInternalNode objects as XMLNode objects
in R already have R-level names.
}
\item{\dots}{additional arguments for the particular methods,
e.g. \code{omitTypes} for an XMLInternalNode.}
}
\value{
A list whose elements are sub-nodes of the user-specified
XMLNode. These are also of class XMLNode.
