Question

I inserted the below command in developer.yahoo.com/yql/console/

yql = select * from yahoo.finance.quotes where symbol in ("XAUUSD=X","XAGUSD=X")

but show all the datas which are not necessary to me. XML Code Generated by Yahoo YQL and Json Code Generated by Yahoo YQL

i 只是想退出Ask、Bid、AskRealtime、BidRealtime、最后一次贸易Realtime Withtime, Last TradeWithtime, Last TradePriceOnly. 我通过使用“加拿大”会议,希望在同一页内将所收集的数据列入“html”表/div。

不能把XML或Json的数据引出。对于我来说,比较容易地 gr取田地和会场数据,并将数据抄送html表。

And also want the grabbed data to be streamable or auto refresh when datas are refreshed in yahoo ..

Answer 1

检查json_decode();!

$x = json_decode($json_string);         // gives back an array
$x = json_decode($json_string, true);   // gives back an object

事情给我提供了很多帮助......

用途

http://api.jquery.com/jQuery.getJSON/

并且把它放在一个时间上。如果你将答复(console.log)记录下来的话,你就会看到,你可以背叛你们想要的东西。

这还需要成为有效的 j子,从而确保它与JSON Lint一样:

http://jsonlint.com/

如果是牙齿(认为人们通常会用str子固住有效的 j子),那么你就不得不使用PHP来获得 j子(档案——植被——接触物或CURL),并在服用有效 j子之前ch。
