\title{Extract the contents of a leaf XML node}
\description{
  Some types of XML nodes have no children nodes, but are leaf nodes and
  simply contain text. Examples are \code{XMLTextMode}, \code{XMLProcessingInstruction}.
  This function provides access to their raw contents.
  This has been extended to operate recursivel on arbitrary XML nodes
  that contain a single text node.
}
\usage{
xmlValue(x, ignoreComments = FALSE)
}
\arguments{
  \item{x}{the \code{XMLNode} object whose
    contents are to be  returned.}
  \item{ignoreComments}{a logical value which, if \code{TRUE}
    does not include the text in XML comment nodes.
    If this is \code{FALSE}, the text in the comments is part
    of the return value.
  }
}
\value{
 The object stored in the 
 \code{value} slot of the \code{XMLNode} object.
 This is typically a string.
