\title{General mechanism for mapping an XML node to an S4 object}
\description{
This generic function and its methods recursively process
an XML node and its child nodes ( and theirs and so on)
to map the nodes to S4 objects.
This is the run-time function that corresponds to the
\code{\link{makeClassTemplate}} function.
}
\usage{
xmlToS4(node, obj = new(xmlName(node)), ...)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
\item{node}{the top-level XML node to convert to an S4 object}
\item{obj}{the object whose slots are to be filled from the
information in the XML node}
\item{\dots}{additional parameters for methods}
}
\value{
The object \code{obj} whose slots have been modified.
