string templates = "group simple; vardef(type,name) ::= \"<name>的属性是<type>;\" 后面还有好多字符串，我就不写这么多吧\"";
            StringTemplateGroup group = new StringTemplateGroup(new StringReader(templates));
            StringTemplate st = group.GetInstanceOf("vardef");
            st.SetAttribute("type", "int");
            st.SetAttribute("name", "foo");

结果是：foo的属性是int;
