Parsing xml stored in string

I have an string encoded in xml format. So when I print it to console it will come out looking like an xml file. What I want to do is read values from this string now using java with DOM or SAX library. But I don't know how to do it because my string is not stored in a file.

<?xml version="1.0" encoding="UTF-8"?>

For DOM, one option is to use an InputSource:

String str = "<xml>...</xml>";
DocumentBuilder builder = DocumentBuilderFactory.newDocumentBuilder();
Document document = builder.parse(new InputSource(new StringReader(str)));

You can use a similar strategy with SAX, since it supports InputSource as well.
