It can't show error when one node does not have close anlge brackets.

I use an xml string like "xxx</b" to test xmldom, which can't show error message for it, but just pass this xml parsed.

How do I use xmldom to make it show error message?

Try assigning errorHandlers when you initialize the DOMParser.

I use a generic wrapper function that looks like this:

 function xmldomWithParseError(xmlString){

// throw exception for any parsing errors or warnings
var errorHandler = function(errorString){
    throw new Error(errorString);
}

// let's throw Exceptions when W3C/node-xmldom XMLParser.parseFromString() encounters any warnings or errors
var domOptions = {
    errorHandler: {
        warning: errorHandler,
        error: errorHandler,
        fatalError: errorHandler
    },

    locator: {}
};

var xmldom = new XmlDom.DOMParser(domOptions).parseFromString(xmlString, 'text/xml');

return xmldom;
}
