Here's a rudimentary setup for Java. You'll need to read up on XPATH queries, and you need to add exception handling etc. But I'm sure this will get you started.

    // open the URL
    URL url = ....
    InputStream is = url.openStream();

    // build a document parser
    DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
    domFactory.setNamespaceAware(true);
    DocumentBuilder builder = domFactory.newDocumentBuilder();

    // parse the document from the URL
    Document d = builder.parse(is);

    // set up XPATH to examine/query the XML
    XPathFactory factory = XPathFactory.newInstance();
    XPath xpath = factory.newXPath();

    // use XPATH query to find the required information
    String sale = xpath.evaluate("/exchangerates/row[@ccy='USD']/@sale", d);

    System.out.println("USD sale is "+sale);
