Parse contour dara in rtss dicom

[youpengly]

How can I get contour data in rtss dicomFile?
I'm using http to get a rtss file from server client and parse it by dicomParser.js, then I should get the contour data by tag '30060050', bind with ct image and show rtss image over ct image in browser;
however the result is string , which split by '', the '' is an escape character,is ignored,so I can't change it
into array and can not get the z position.

Thanks sincerely!

dicomParser.readFixedString = function (byteArray, position, length) {
if (length < 0) {
throw 'dicomParser.readFixedString - length cannot be less than 0';
}

        if (position + length > byteArray.length) {
            throw 'dicomParser.readFixedString: attempt to read past end of buffer';
        }

        var result = "";
        var byte;
        for (var i = 0; i < length; i++) {
            byte = byteArray[position + i];
            if (byte === 0) {
                position += length;
                return result;
            }
            result += String.fromCharCode(byte);
        }

        return result;
    };
