Question

我正在使用java解析xml文档。我尝试从特殊节点获取完整的文本。

这是我的xml文档

<xml><archi><test>asd</test></archi><brchi val="a"><asd>Hello</asd><bsd>World</bsd></brchi></xml>

我在这里解析文档：

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        Document doc = builder.parse(new URL(url).openStream());

        doc.getDocumentElement().normalize();
        Element root = doc.getDocumentElement();

        // loop through each item
        NodeList nList = doc.getElementsByTagName("brchi"); 
        for (int temp = 0; temp < nList.getLength(); temp++) {
                Node nNode = nList.item(temp); ...

这很有效。但现在我想从我解析的元素中获取完整的文本。在这里＆＃34; brchi＆＃34;。这应该是结果：

<brchi val="a"><asd>Hello</asd><bsd>World</bsd></brchi>

但是我怎样才能获得文本而不是解析元素？

Answer 1

可能有一种更清洁的方式，但我所做的是给出了XML：

<book ISBN="0123456001">
    <title>Java For Dummies</title>
    <author>Tan Ah Teck</author>
    <category>Programming</category>
    <year>2009</year>
    <edition>7</edition>
    <price>19.99</price>
</book>

这是我用来提取标题文本的代码

NodeList list = doc.getElementsByTagName("title");
Element element = (Element)list.item(0)
System.out.println("\tTitle:\t"
                   + element.getChildNodes().item(0).getNodeValue());`

试试这个：

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

try {
    DocumentBuilder builder = factory.newDocumentBuilder();
    Document doc = builder.parse(new File("data.xml"));



    NodeList list = doc.getElementsByTagName("brchi");
    Node node = list.item(0);

    TransformerFactory tFactory = TransformerFactory.newInstance();
    Transformer transformer = tFactory.newTransformer();
    DOMSource source = new DOMSource(node);

    StreamResult result = new StreamResult(System.out);
    transformer.transform(source, result);


    } catch (ParserConfigurationException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (SAXException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (TransformerException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}
