The XML Serializer Type

The XMLSerializer type converts a DOM document to a XML string. This type is used to perform a reverse operation of DOMParser. To serialize a DOM document, an instance of XMLSerializer is created and serializeToString() method is called. When a non-DOM object is passed to serialize, an error will be thrown. This feature is supported in IE 9+, Safari, Chrome, and Opera.

The example below converts a string to a DOM document. The string is retrieved from that DOM document back using the serializer.

Example of the XML Serializer type

<!DOCTYPE html>
<html>

<style>
    p{font-size:smaller;color:lightblue;background-color:blue;}
</style>

<body>
<script>
    var str = "<note><to>Sandesh</to><from>Rosy</from><msg>Let's meet this weekend!</msg></note>";			
    try 
    {
        if(window.DOMParser){			
            var parser = new DOMParser();	
            var xmlDoc = parser.parseFromString(str, "text/xml"); 
            var error = xmlDoc.getElementsByTagName("parsererror");
            if (error.length == 0)
            {
                var serializer = new XMLSerializer();
                var str = serializer.serializeToString(xmlDoc);
                document.write("OUTPUT:<p>" + str + "</p>");
            }
        }
        else{
            xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
            xmlDoc.async=false;
            xmlDoc.loadXML(str);
            if (xmlDoc.parseError.errorCode == 0) 
            {
                var serializer = new XMLSerializer();
                var str = serializer.serializeToString(xmlDoc);
                alert(str);
            }
        }
    }catch(e){
        alert(e.message);
    }	
</script>
</body>
