Java如何在JDOM中设置XML元素的文本内容？
本示例说明如何设置XML元素的文本内容。在JDOM中，我们可以轻松插入诸如HTML标签之类的文本，而不必担心转义标签。JDOM将自动执行此转换。
package org.nhooo.example.jdom;
import org.jdom2.Document;
import org.jdom2.Element;
import org.jdom2.JDOMException;
import org.jdom2.input.SAXBuilder;
import org.jdom2.output.Format;
import org.jdom2.output.XMLOutputter;
import java.io.IOException;
import java.io.StringReader;
public class JDOMSetTextContent {
public static void main(String[] args) {
String xml = "<root>" +
" <description>" +
" </description>" +
"</root>";
SAXBuilder builder = new SAXBuilder();
try {
Document document = builder.build(new StringReader(xml));
Element root = document.getRootElement();
Element description = root.getChild("description");
//将文本内容添加到description元素。字符串
//会自动转义，因此我们不必使用
// < and > symbol.
description.setText("This is an <strong>IMPORTANT</strong> " +
"description");
XMLOutputter outputter = new XMLOutputter(Format.getPrettyFormat());
outputter.output(document, System.out);
} catch (JDOMException | IOException e) {
e.printStackTrace();
}
}
