<!--- Query the database and get the names in the employee table --->
<cfquery name="myQuery" datasource="cfdocexamples">
SELECT FirstName, LastName

<!--- Create an XML document object containing the data --->

<employee>
<cfoutput query="myQuery">

<!--- dump the resulting XML document object --->
<cfdump var=#mydoc#>
<!--- Write the XML to a file --->

Validating XML documents
ColdFusion provides the following methods for validating a document against a DTD or an XML Schema:
• The function can validate XML text that it is parsing against a DTD or Schema. It the function
XmlParse
encounters a validation error, ColdFusion generates an error and stops parsing the text. If the validator generates
warnings, but no errors, ColdFusion parses the document and returns the result.
• The function can validate an XML text document or XML document object. against a DTD or
XmlValidate
Schema. The function returns a data structure with detailed information from the validator, including arrays of
warning, error, and fatal error messages, and a Boolean status variable indicating whether the document is valid.
Your application can examine the status information and determine how to handle it further.
For examples of XML validation, see

Transforming documents with XSLT
The Extensible Stylesheet Language Transformation (XSLT) technology transforms an XML document into another
format or representation. For example, one common use of XSLT is to convert XML documents into HTML for
display in a browser. XSLT has many other uses, including converting XML data to another format, such as converting
XML in a vocabulary used by an order entry application into a vocabulary used by an order fulfillment application.
XSLT transforms an XML document by applying an Extensible Stylesheet Language (XSL) style sheet. (When stored
in a file, XSL style sheets typically have the .xsl extension.) ColdFusion provides the
an XSL transformation to an XML document. The function takes an XML document in string format or as an XML
document object, and an XSL style sheet in string format, and returns the transformed document as a string.
The following code:
