\title{Get the names of an XML nodes children.}
\description{
This is a convenient way to obtain the XML tag name
of each of the sub-nodes of a given
\code{XMLNode} object.
}
\usage{
\method{names}{XMLNode}(x)
}
\arguments{
\item{x}{the \code{XMLNode} whose sub-node tag names are being
queried.}
}
\value{
A character vector returning the
tag names of the sub-nodes of the given
\code{XMLNode} argument.

\note{ This overrides the regular names method
which would display the names of the internal
fields of an \code{XMLNode} object.
Since these are intended to be invisible and
queried via the accessor methods (\code{\link{xmlName}},
\code{\link{xmlAttrs}}, etc.), this should not
be a problem. If you really need the names
of the fields, use \code{names(unclass(x))}.
