Usage
This function determines whether text is well-formed XML, that is, it conforms to all XML
syntax and structuring rules. The string does not have to be a complete XML document. The
function does not validate against a Document Type Definition (DTD) or XML Schema.
Example
The following example creates two strings, and tests whether they are well-formed XML text:
<!--- A well formed XML string --->
<cfset xmlString1='<order id="4323251">
<customer firstname="Philip" lastname="Cramer" accountNum="21"/>
<items>
<item id="43">
<quantity>1</quantity>
<unitprice>15.95</unitprice>
</item>
</items>
</order>'
>
<!--- An invalid XML string, missing the </item> close tag --->
<cfset xmlString2='<order id="4323251">
<customer firstname="Philip" lastname="Cramer" accountNum="21"/>
<items>
