在Java中打印XML而不使用XML文件标记

有没有一种方法可以在Java中打印XML内容而不使用XML头标记

例如，如果我有这样一个XML：

<?xml version='1.0' encoding='UTF-8'?>
<rootElement>
<childElement>Text</childElement>
</rootElement>

好的和旧的XSL；）

您是如何编写xml的？使用哪个库/工具？你能发布java代码吗？里面甚至有一个字符串常量。

<rootElement>
<childElement>Text</childElement>
</rootElement>

public String convertXMLFileToString(String fileName) 
        { 
          try{ 
            DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance(); 
            InputStream inputStream = new FileInputStream(new File(fileName)); 
            org.w3c.dom.Document doc = documentBuilderFactory.newDocumentBuilder().parse(inputStream); 
            StringWriter stw = new StringWriter(); 
            Transformer serializer = TransformerFactory.newInstance().newTransformer(); 
            serializer.transform(new DOMSource(doc), new StreamResult(stw)); 
            return stw.toString(); 
          } 
          catch (Exception e) { 
            e.printStackTrace(); 
          } 
            return null; 
        }

Transformer serializer = TransformerFactory.newInstance().newTransformer();
serializer.setOutputProperty("omit-xml-declaration", "yes");
serializer.transform(new DOMSource(doc), new StreamResult(stw));
