JSON 之 SuperObject(14): 从 XML 中解析

SuperObject 文件包中还有一个 SuperXmlParser 单元, 可以从 XML 中解析出 ISuperObject.

SuperXmlParser 只有三个函数: XMLParseString、XMLParseStream、XMLParseFile, 分别从字符串、流、文件中解析.

遗憾的是对中文不够友好.

  ShowMessage(jo.AsString);



  ShowMessage(jo['Name.Name'].AsString); {张三}

  ShowMessage(jo['Name.sex'].AsString);  {男}

  ShowMessage(jo['Age'].AsString);       {123}

end;



end.
