/**
 * phpSimpeXML - A easy to use php class for reading and writing XML.
 *
 * Options only for XMLin():
 * 
 *	   $opt["forcecontent"] = 1; (default 0)
 * 
 *		   <i>This option allows you to force text content to always parse to
 *		   a associative array even when there are no attributes.</i>
 * 
 * 
 * 
 * Options only for XMLout():
 * 
 *	   $opt["filename"] = "example.xml"; (default "")
 * 
 *		   <i>The default behaviour of XMLout() is to return the XML as a string.  If you
 *		   wish to write the XML to a file, simply supply the filename using the
 *		   'filename' option.</i>
 * 
 * 
 * 
 * Options for XMLin() and XMLout():
 * 
 *	   $opt["contentkey"] = "keyname"; (default "content")
 * 
 *		   <i>When text content is parsed to a associative array, this option let's you specify a
 *		   name for the associative array key to override the default 'content'.</i>
 * 
 *	   $opt["keeproot"] = 1; (default 0)
 * 
 *		   <i>In its attempt to return a data structure free of superfluous detail and
 *		   unnecessary levels of indirection, XMLout() normally discards the root
 *		   element name.  Setting the 'keeproot' option to '1' will cause the root element
 *		   name to be retained.</i>
 * 
 *
 * 
 * Use this options like
 *	   $xml = XMLin("example.xml", $opt);
 * or
 *	   $output = XMLout($xml, $opt);
