如何在Value中获取XML节点角度约束

Question

我希望我的XML节点为：

<Name><![CDATA[Masonry, Stucco &amp; Brick Paint]]></Name>

但它被保存为：

<Name>&lt;![CDATA[Abcd, City &amp; Abcd]]&gt;</Name>

我使用的代码如下：

import org.w3c.dom.Document;
import org.w3c.dom.Element;
...
...
Element name = doc.createElement("Name");
name.appendChild(doc.createTextNode("<![CDATA[" + categoryName + "]]>"));
category.appendChild(name);

  

我甚至尝试使用＆＃34; amp; lt;＆＃34;和＆＃34; amp; gt;＆＃34; for＆lt;和＆gt;分别但不起作用

你可以试试这个......

class StringToDocumentToString {

    public static void main(String[] args) {

        final String xmlStr = "<Name><![CDATA[Masonry, Stucco &amp; Brick Paint]]></Name>";

        Document doc = convertStringToDocument(xmlStr); //You can directly store this document as .xml but if you want String as return than do next step
        String str = convertDocumentToString(doc);
        System.out.println(str);
    }

    private static String convertDocumentToString(Document doc) {
        TransformerFactory tf = TransformerFactory.newInstance();
        Transformer transformer;
        try {
            transformer = tf.newTransformer();
            StringWriter writer = new StringWriter();
            transformer.transform(new DOMSource(doc), new StreamResult(writer));
            String output = writer.getBuffer().toString();
            return output;
        } catch (TransformerException e) {
            e.printStackTrace();
        }

        return null;
    }

    private static Document convertStringToDocument(String xmlStr) {
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder;
        try {
            builder = factory.newDocumentBuilder();
            Document doc = builder.parse(new InputSource(new StringReader(
                    xmlStr)));
            return doc;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

}
