在Java中将Element（org.w3c.dom）转换为String [英] Convert Element(org.w3c.dom) to String in Java

问题描述

将Element对象转换为String时遇到一个小问题。因为我需要将字符串传递给特定方法。我尝试使用.toString（）或使用分配给它的String变量进行尝试。没有一个试验是正确的。我们如何轻松地进行转换，并且字符串对象还应该显示与Element一样的确切XML结构。

I'm having a small issue of converting Element object to String. Because I need a string to be passed to a particular method. I've tried by using .toString() or using a String variable assigning to it. None of the trials were correct. How can we easily convert and the string object also should show the exact XML structure as it is showing for Element.

Element element = (Element) xmlList.item(i);

以上 element对象以XML格式显示。我想将相同的字符串转换为XML格式

The above "element" object shows in XML format. I want to convert the same in String in XML format

推荐答案

 import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;

import java.io.StringWriter;

TransformerFactory transformerFactory = TransformerFactory
                    .newInstance();
            Transformer transformer = transformerFactory.newTransformer();
            DOMSource source = new DOMSource(<your-element-obj>);
            StreamResult result = new StreamResult(new StringWriter());



            transformer.transform(source, result);

            String strObject = result.getWriter().toString();
