在解析xml字符串时出现no protocol错误。

[baoqingfeng]

String data=request.getParameter("data");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(data);
data 内容如下：<?xml version="1.0" encoding="GBK"?><root><Node col1="10" col2="4" col3="1" col4="" col5="2005-5-5" col6="4" col7="" col8="" col9=""/></root>
修改为如下也是一样的错误。
<?xml version="1.0" encoding="ISO-8859-1"?><!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"><root><Node col1="11" col2="2" col3="1" col4="" col5="2004-4-4" col6="2" col7="" col8="" col9=""/></root>

错误如下：
java.net.MalformedURLException: no protocol: <?xml version="1.0" encoding="GBK"?><root><Node col1="10" col2="4" col3="1" col4="" col5="2005-5-5" col6="4" col7="" col8="" col9=""/></root>

//db.parse(data);

此处的data是个文件路径或者url,而不是直接的xml内容.



String data="c:\\text.xml";

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(data);
