是否有比此代码更优雅的方式将XML文档转换为Java中的字符串? [英] Is there a more elegant way to convert an XML Document to a String in Java than this code?

问题描述

这是当前使用的代码.

public String getStringFromDoc(org.w3c.dom.Document doc)    {
        try
        {
           DOMSource domSource = new DOMSource(doc);
           StringWriter writer = new StringWriter();
           StreamResult result = new StreamResult(writer);
           TransformerFactory tf = TransformerFactory.newInstance();
           Transformer transformer = tf.newTransformer();
           transformer.transform(domSource, result);
           writer.flush();
           return writer.toString();
        }
        catch(TransformerException ex)
        {
           ex.printStackTrace();
           return null;
        }
    }

推荐答案

依赖 DOM Level3加载/保存:

public String getStringFromDoc(org.w3c.dom.Document doc)    {
    DOMImplementationLS domImplementation = (DOMImplementationLS) doc.getImplementation();
    LSSerializer lsSerializer = domImplementation.createLSSerializer();
    return lsSerializer.writeToString(doc);   
}
