copied!<p>Creating a Java DOM XML parser is done using the javax.xml.parsers.DocumentBuilderFactory class. Here is an example:</p> <pre><code>DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance(); DocumentBuilder builder = null; try { builder = builderFactory.newDocumentBuilder(); } catch (ParserConfigurationException e) { e.printStackTrace(); } </code></pre> <p>Parsing an XML file into a DOM tree using the DocumentBuilder is done like this:</p> <pre><code>try { Document document = builder.parse( new FileInputStream("data\\text.xml")); } catch (SAXException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } </code></pre> <p>At the top is the Document object. The Document object has a single root element, which is returned by calling getDocumentElement() like this:</p> <pre><code>Element rootElement = document.getDocumentElement(); </code></pre> <p>get the children of an element</p> <pre><code>NodeList nodes = element.getChildNodes(); for(int i=0; i<nodes.getLength(); i++){ Node node = nodes.item(i); if(node instanceof Element){ //a child element to process Element child = (Element) node; String attribute = child.getAttribute("width"); } } </code></pre> <p>Now you have a needed Node, so you can create put it in map as you wish, and make need for you key. method transformer.transform(new DOMSource(document),work with any Dom node or element</p> <p>Create String from Document</p> <pre><code>TransformerFactory transFactory = TransformerFactory.newInstance(); Transformer transformer = transFactory.newTransformer(); StringWriter buffer = new StringWriter(); transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes"); transformer.transform(new DOMSource(document), new StreamResult(buffer)); String str = buffer.toString(); </code></pre>
