Version: 1 | Requires: ColdFusion 5 | Library: StrLib

Rated 1 time(s). Average Rating: 5.0

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

Parameters:

Name	Description	Required
string	String to format.	Yes
