#ifdef MOZILLA_OS
#define _XHTML_
#endif

#ifdef _XHTML_
int print()
{
printf("<node />");
}
#endif

#ifndef _XHTML_
int print()

var XHTML;

if(OS=="MOZILLA")
{

} else {XHTML=0;};

if (XHTML)
{
 function print() {document.write("<node />");};
} else {
 function print() {document.write("<node></node>");};
};
