JSON 之 SuperObject(14): 從 XML 中解析

SuperObject 文件包中還有一個 SuperXmlParser 單元, 能夠從 XML 中解析出 ISuperObject.

SuperXmlParser 只有三個函數: XMLParseString、XMLParseStream、XMLParseFile, 分別從字符串、流、文件中解析.

遺憾的是對中文不夠友好.

//使用壓縮
procedure TForm1.Button2Click(Sender: TObject);
var
  jo: ISuperObject;
begin
  jo := XMLParseString('<Person><Name sex="男">張三</Name><Age>123</Age></Person>', True);
  ShowMessage(jo.AsString);

  ShowMessage(jo['Name.Name'].AsString); {張三}
  ShowMessage(jo['Name.sex'].AsString);  {男}
  ShowMessage(jo['Age'].AsString);       {123}
end;

end.
