    copied!<p>I am absolutly new in <strong>XML Parsing</strong> and in <strong>XPATH query</strong> in Java and I have the following problem:</p> <p>I have the following XML file on which I have to do some queries:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;root&gt; &lt;status&gt; &lt;id&gt;0&lt;/id&gt; &lt;message /&gt; &lt;/status&gt; &lt;objectList&gt; &lt;object id="obj1"&gt; &lt;property1&gt;value&lt;/property1&gt; &lt;property2&gt;value&lt;/property2&gt; &lt;property3 /&gt; &lt;/object&gt; &lt;object id="obj2 "&gt; &lt;property1&gt;value&lt;/sproperty1&gt; &lt;property2&gt;value&lt;/property2&gt; &lt;property3&gt;value&lt;/property3&gt; &lt;/object&gt; &lt;object id="obj3 "&gt; &lt;property1&gt;value&lt;/sproperty1&gt; &lt;property2&gt;value&lt;/property2&gt; &lt;property3&gt;value&lt;/property3&gt; &lt;/object&gt; &lt;/objectList&gt; &lt;/root&gt; </code></pre> <p>The first thing that I have to do is take the value inside the unique <strong><code>&lt;id&gt;0&lt;/id&gt;</code></strong> tag and I have do it using the following XPATH query (and this query work well):</p> <pre><code>XPath xPath = XPath.newInstance("s:Envelope/s:Body"); xPath.addNamespace("s", "http://schemas.xmlsoap.org/soap/envelope/"); org.jdom.Element objectElement = (Element) xPath.selectSingleNode(documentXML); System.out.println("objectElement: " + objectElement); </code></pre> <p>(where <strong>documentXML</strong> contains the previous XML document)</p> <p>This work well and put inside my <strong>objectElement</strong> object the value 0 that is inside the <strong><code>&lt;id&gt;0&lt;/id&gt;</code></strong> tag.</p> <p>Ok, now I have to perform a more complex operation (and I have no many ideas about how do it) that is the following one:</p> <p>As you can see I have a tag named <strong>objectList</strong> that contains 3 tag named <strong>object</strong> that represent a list of 3 Java objects having some some properties (<strong>property1</strong>, <strong>property2</strong> and <strong>property3</strong> that will be 3 variables into the related Java objectt)</p> <p>Now I have to perform the following operations: <strong>for each object tag inside the XML document create a new Java object and put the property subtag value inside the related value in the new Java object</strong></p> <p>The problem is that I have no idea about scroll through the list of obecjt tags that areinside my tag (from the first to the last)</p> <p>Some idea? Someone can help me to do it?</p> <p>Tnx</p> <p>Andrea</p>
