解析xml字符串出现java.net.MalformedURLException: no protocol的解决办法

使用jdom解析xml字符串代码如下

String xml = "<root>......</root>";
SAXBuilder builder = new SAXBuilder();
Document doc = builder.build(xml);

运行时，抛异常java.net.MalformedURLException: no protocol......

解决办法如下：

String xml="<root>......</root>";
SAXBuilder builder = new SAXBuilder();
Document doc = builder.build(new ByteArrayInputStream(xml.getBytes()));
