如何从String中删除Xml版本字符串

我使用下面给出的代码阅读了Xml文件 – 

String XmlString = ""; String resourcePath=FilePathHelper.getResourceFilePath(request); BufferedReader br = new BufferedReader(new FileReader(new File(resourcePath+ "SubIndicatorTemplate.xml"))); String line; StringBuilder sb = new StringBuilder(); while((line=br.readLine())!= null){ sb.append(line.trim()); } XmlString=sb.toString();

现在我以下面给出的格式得到XmlString sting- 

 <Title /></code> </pre>
<p> 我想从上面的字符串中删除<code></code> 。所以我写了代码为 </p>
<pre> <code>XmlString=XmlString.replaceAll("", "").trim();</code> </pre>
<p> 但是XmlString仍然是一样的。 所以请帮我从XmlString中删除版本信息。 </p>
