DTD Validation
With Internet Explorer 5+ you can validate your XML against a DTD.
Validating With the XML Parser
If you try to open an XML document, the XML Parser might generate an error.
By accessing the parseError object, you can retrieve the error code, the error text,
or even the line that caused the error.
Note: The load( ) method is used for files, while the loadXML( )
method is used for strings.
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async="false";
xmlDoc.validateOnParse="true";
xmlDoc.load("note_dtd_error.xml");
document.write("<br />Error Code: ");
document.write(xmlDoc.parseError.errorCode);
document.write("<br />Error Reason: ");
document.write(xmlDoc.parseError.reason);
document.write("<br />Error Line: ");
document.write(xmlDoc.parseError.line); |
Try it Yourself
or just look at the XML file
Turning Validation Off
Validation can be turned off by setting the XML parser's validateOnParse="false".
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async="false";
xmlDoc.validateOnParse="false";
xmlDoc.load("note_dtd_error.xml");
document.write("<br />Error Code: ");
document.write(xmlDoc.parseError.errorCode);
document.write("<br />Error Reason: ");
document.write(xmlDoc.parseError.reason);
document.write("<br />Error Line: ");
document.write(xmlDoc.parseError.line); |
