\title{ Determines which native XML parsers are being used.}
\description{
Use of the Gnome libxml and Expat parsers is supported
in this R/S XML package, but both need not be used when
compiling the package. These functions determine whether
each is available in the underlying native code.
}
\usage{
supportsExpat()
supportsLibxml()
}
\details{
One might to use different parsers to test
validity of a document in different ways and
to get different error messages. Additionally,
one parser may be more efficient than the other.
These methods allow one to write code in such
a way that one parser is preferred and is used
if it is available, but the other is used
if the first is not available.
}
\value{
Returns \code{TRUE} if the corresponding library
has been linked into the package.
