    copied!<p>I would need to build a simple program for my homework purposes that will retrieve data from an XML attribute based on the user input in a web service. To that end, I assumed I would start building a class that could parse my XML string and also I built a simple java service that does nothing but responds with a simple message. The problem is how do I put these together in order to get my program to work? Is this a good way to begin with? Please advise.</p> <p>Also, to make thing a little more easier, the data in the string representation of XML has key words in both English and Serbian that would enable this web service to retrieve from one another:</p> <pre><code>import java.io.IOException; import java.io.StringReader; import javax.xml.parsers.DocumentBuilder; import javax.xml.parsers.DocumentBuilderFactory; import javax.xml.parsers.ParserConfigurationException; import org.w3c.dom.Document; import org.w3c.dom.Element; import org.w3c.dom.Node; import org.w3c.dom.NodeList; import org.xml.sax.InputSource; import org.xml.sax.SAXException; public class Recnik { public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException { String xmlString = "&lt;?xml version=\"1.0\" encoding=\"UTF-8\"?&gt;&lt;!DOCTYPE language [&lt;!ATTLIST phrase id ID #IMPLIED&gt;]&gt;&lt;language id=\"sr\"&gt;&lt;phrase key=\"house\" value=\"kuca\"/&gt;&lt;phrase key=\"dog\" value=\"pas\"/&gt;&lt;phrase key=\"cat\" value=\"macka\"/&gt;&lt;/language&gt;"; DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db = dbf.newDocumentBuilder(); //FileInputStream fis = new FileInputStream("myBooks.xml"); InputSource is = new InputSource(new StringReader(xmlString)); Document doc = db.parse(is); Element r = doc.getDocumentElement(); NodeList language = r.getElementsByTagName("phrase"); System.out.println(language.item(1).getAttributes().item(0).getTextContent()); } } package Prevodilac; import javax.jws.WebService; import javax.jws.WebMethod; import javax.jws.WebParam; @WebService(serviceName = "Prevodilac") public class Prevodilac { @WebMethod(operationName = "pretraga") public String pretraga(int a, int b) { Integer res = a+b; return res.toString(); } } </code></pre>
