#' Create XML empty node "stretch" for RKWard plugins
#'
#' The simplest way to use \code{rk.XML.stretch} is to call it without arguments.
#' If you provide \code{before} and/or \code{after}, a "<stretch />" will be put between
#' the XML elements defined there.
#'
#' @param before A list of objects of class \code{XiMpLe.node}.
#' @param after A list of objects of class \code{XiMpLe.node}.
#' @return An object of class \code{XiMpLe.node}.
#' @export
#' @seealso
#' \href{help:rkwardplugins}{Introduction to Writing Plugins for RKWard}
#' @examples
#' cat(pasteXML(rk.XML.stretch()))
#<stretch />
rk.XML.stretch <- function(before=NULL, after=NULL){
strch <- XMLNode("stretch")
# if called without furter objects, just return the node
if(is.null(c(before, after))){
return(strch)
} else {}
if(!is.null(before)){
strch.lst <- child.list(before)
strch.lst[[length(strch.lst)+1]] <- strch
} else {
strch.lst <- list(strch)
}
if(!is.null(after)){
for(this.element in child.list(after)){
strch.lst[[length(strch.lst)+1]] <- this.element
}
} else {}
return(strch.lst)
}
