It uses cfquery to get a list of employees from the cfdocexamples database and saves the information as an XML document. SELECT FirstName, LastName FROM employee #FirstName# #LastName# 1270 Using XML and WDDX
Beta Beta Beta Beta Beta Beta Beta Beta Beta Beta 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 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 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 and in CFML Reference. The XmlParse example validates a document using a DTD. The XmlValidate example validates the document using an XML Schema that represents the same document structure as the DTD. 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) stylesheet. (When stored in a file, XSL stylesheets typically have the suffix xsl.) ColdFusion provides the function to apply 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 stylesheet in string format, and returns the transformed document as a string. The following code: 1. Reads the simpletransform.xsl stylesheet file into a string variable. 2. Uses the stylesheet to transform the mydoc XML document object. 3. Saves the resulting transformed document in a second file.
