Version: 1 | Requires: CF5 | Library: StrLib

Description:
This is a simple UDF which does the exact opposite of CFMX's XmlFormat() function. Specifically, it replaces the following five characters in XML-escaped data with their normal equivalents: > with > < with < ' with ' " with " & with &

Return Values:
Returns a string.

Example:

<cfscript>
XmlSafe="&quot;That&apos;s a very safe string &amp; &lt;TAG&gt; you&apos;re it!!!&quot;";
XmlUnsafe=XmlUnformat(XmlSafe);
WriteOutput(htmlCodeFormat(XmlUnsafe));
</cfscript>

Parameters:

Name Description Required
string String to format. Yes

 * 
 * @param string 	 String to format. (Required)
 * @return Returns a string.
