Example

The following example shows how XmlFormat escapes special XML characters. Use the View Source command in the browser to see the results. ColdFusion interprets the "" in the second text string as representing a single-quotation mark in text before it applies the XmlFormat function.

<?xml version = "1.0"?> 
<cfoutput>
<someXML>
    <someElement someAttribute="#XmlFormat("'a quoted value'")#"> 
        #XmlFormat("Body of element with <, >, "" and & goes here.")#
    </someElement>
</someXML>
</cfoutput>
