Question

I have problem with evaluation XPath expression in Windows Script Host using JScript when
is present on top of document. When I remove DOCTYPE parsing doesnt break. Here is sample of code that I am using to parse and load xml. Is there any way to parse this kind of XML witout removing DOCTYPE declaration.

I dont want to delete DOCTYPE while processing. Solution could be to remove DOCTYPE using Regex
<!DOCTYPE.*?>/gm; but I dont want solution like that.

var XmlDocument;
    try {
        XmlDocument = new ActiveXObject("msxml2.DOMDocument.6.0");
        XmlDocument.async = false;
        XmlDocument.resolveExternals = false;
        XmlDocument.validateOnParse = false;
    } catch(e) {
        if(debug == true)
            WScript.echo("***ERROR while creating DOM Object: " + e.description);
    }
    // Load an XML file into the DOM instance
    try {
        XmlDocument.load(filePath);
    } catch(e) {
        if(debug == true)
            WScript.echo("***ERROR LOADING FILE: " + e.description);
    }
    var Node;
    try {
        Node = XmlDocument.selectSingleNode("//metadata/url");
    } catch(e) {
        if(debug == true)
            WScript.echo("***ERROR RESOLVING NODE: " + e.description);
    }

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE rightinclude SYSTEM "http://localhost/iw/aa.dtd">
<a>
    <b>
        <c>/someurl.html</c>
    </b>
</a>

Answer 1

Have you tried it when the DOCTYPE element is closed – some parsers will take the document in this case.

e.g:

<!DOCTYPE rightinclude SYSTEM "http://localhost/iw/aa.dtd" />
