解决java.net.MalformedURLException_unknown protocol_c问题

最近在工作中遇到的问题，困扰了很长时间。

• 修改前代码：

  DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

  DocumentBuilder builder = factory.newDocumentBuilder();

  Document document = builder.parse(xmlPath); \直接将路径名给builder.

• 修改后代码：

  DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

  DocumentBuilder builder = factory.newDocumentBuilder();

  Document document = builder.parse(“file:///“ + xmlPath);
