These two classes allow the user to identify an XML document or file
 as containing R code (amongst other content). Objects of either of these
 classes can then be passed to <code><a href="/link/source?package=XML&version=3.1-1" rd-options="" data-mini-rdoc="XML::source">source</a></code> to read the 
 code into R and also used in <code>link{xmlSource}</code> to read just parts of it.
 <code>XMLCodeFile</code> represents the file by its name;
 <code>XMLCodeDoc</code> parses the contents of the file when the R object is created.
 Therefore, an <code>XMLCodeDoc</code> is a snapshot of the contents at a moment in time
 while an <code>XMLCodeFile</code> object re-reads the file each time and so reflects
 any "asynchronous" changes.

XMLCodeFile-class

This package provides many approaches for both reading and
        creating XML (and HTML) documents (including DTDs), both local
