See alsoIsXmlAttribute, IsXmlDoc, IsXmlElem, IsXmlNode, IsXmlRoot, XmlParse, XmlValidate; Using XML and WDDX in the Developing ColdFusion Applications UsageThis 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. ExampleThe 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> <item id="43"> <quantity>1</quantity> <unitprice>15.95</unitprice> </items> </order>' > <!--- Test the strings to see if they are well formed XML ---> <cfoutput> xmlString1 contains the following text:<br><br> #HTMLCodeFormat(xmlstring1)# Is it well formed XML text? #IsXML(xmlString1)#<br><br> <hr> xmlString2 contains the following text:<br><br> #HTMLCodeFormat(xmlstring2)# Is it well formed XML text? #IsXML(xmlString2)# </cfoutput> |
