\title{Accessors for name of XML document}
\description{
These functions and methods allow us to query and set the
\dQuote{name} of an XML document. This is intended to be
its URL or file name or a description of its origin if
raw XML content provided as a string.
}
\usage{
docName(doc, ...)
}
\arguments{
\item{doc}{the XML document object, of class
\code{XMLInternalDocument} or \code{XMLDocument}.
}
\item{\dots}{additional methods for methods}
}
\value{
A character string giving the name.
If the document was created from text, this is \code{NA}
(of class character).
The assignment function returns the updated object,
but the R assignment operation will return the value
on the right of the assignment!
