    copied!<p>There is a multitude of ways to achieve this. I assume you read this once for a long-running application, so performance shouldn't be an issue. Therefore, I'd go for the Java XPath API (<a href="http://www.ibm.com/developerworks/library/x-javaxpathapi.html" rel="nofollow noreferrer">Tutorial</a>).</p> <p>Here is a fully working example using XPath (note: just replace the <code>StringReader</code> with any <code>Reader</code> that's appropriate for your usecae - e.g. a <code>FileReader</code>):</p> <pre><code>import java.io.StringReader; import javax.xml.xpath.XPathFactory; import org.xml.sax.InputSource; public class XPath { public static void main(String[] args) throws Exception { String xml = "&lt;hibernate-configuration&gt;&lt;session-factory&gt;&lt;property name=\"hibernate.connection.provider_class\"&gt;org.hibernate.connection.C3P0ConnectionProvider&lt;/property&gt;&lt;property name=\"connection.driver_class\"&gt;com.mysql.jdbc.Driver&lt;/property&gt;&lt;property name=\"connection.url\"&gt;jdbc:mysql://192.168.1.55/tisas&lt;/property&gt;&lt;/session-factory&gt;&lt;/hibernate-configuration&gt;"; String connectionUrl = XPathFactory.newInstance().newXPath().compile("//session-factory/property[@name='connection.url']/text()").evaluate(new InputSource(new StringReader(xml))); System.out.println("connectionUrl = " + connectionUrl); } } </code></pre> <p>I wouldn't go for a DOM (as suggested by Ram) if you only need a single value from the file, it will require more code.</p>
