推荐答案

技术在我的博客帖子中概述了 Yahoo的不成熟指南Query Langauge

You can use the technique outlined in my blog post Unwritten guide to Yahoo Query Langauge

您将使用如下所示的yql语法查询XML数据表：

You would query the XML data table with a yql statment like this:

select * from xml
  where url="http://path/to/xml

然后， （可以使用document.createElement（'script'））与一个src http://query.yahooapis.com/v1/public/yql?q={your这里}&format = json&callback = {您的函数here}其中{your yql here}替换为您的yql编码的URI编码版本。

Then you would add a script tag to your html (can be done with document.createElement('script')) with a src http://query.yahooapis.com/v1/public/yql?q={your yql here}&format=json&callback={your function here} where {your yql here} is replace with a URI Encoded version of you yql statment.
