Write a Web page that uses JavaScript and msxml to validate XML documents. Display either a message indicating the document is valid or an error message indicating that the document does not conform to its DTD/schema. Error messages should include line numbers as well as a description. [Hint: Use Microsoft’s XMLDOMParseError object to check for parse errors and property reason to get a description of why a document failed validation.]
What will be an ideal response?
