DTD verify

Using Internet Explorer, you can validate your XML against a DTD.

Validation via XML parser

When you attempt to open an XML document, the XML parser may generate errors. By accessing the parseError object, you can retrieve the exact code, text, and even the line where the error occurred.

Note:The load() method is used for files, while the loadXML() method is used for strings.

Example

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);

disable validation

By setting the XML parser's validateOnParse to "false", you can turn off validation.

Example

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);
