I'd like to retrieve data from a web site ,which does not provide a API
Can I retrieve data using YQL?
ie: Can I custom the data parse in the target URI with YQL?
Yes, you can. This is one of the most popular use case of YQL. Here is a sample. But it is not working when trying to retrieve data from web-page which is dissallowed for spider access (via robots.txt, for example).
Without knowing what you're trying to do, the only reasonable answer here is…
Yes.

I'm trying to implement a jqxGrid, using sorting and paging on the server. I don't have access to the server itself. Taking an example from:
http://www.jqwidgets.com/jquery-widgets-documentation/documentation/phpintegration/php-server-side-grid-paging-and-sorting.htm
I implement the client-side and want to use a mock static file as a response. I can't manage to figure out what kind of JSON response format is meant to be returned.
How do I 'catch' and edit/format the JSON response from the server? (Where in the code?)
Is there anywhere a working example of a jqgrid with sorting done on the server, to be viewable online? (So I can observe the data structure returned).
What do you mean exactly? Do you want to edit the data itself or the view of the data? If it is the later one you can use cellsrendered. For a live demo look here. You can also change the value here since you have access to the value field but it is by column.
Yes, look here.
http://www.jqwidgets.com/jquery-widgets-documentation/
You can find there information about the datasource.

You can find there (right menu):

You can find there what ever yo need (sorting filtering and so)
so basically I'm trying to display the latest tweets from 5-10 different sources/twitter accounts in a new application I'm trying to make.
Similarly the way tweetro/metrotwit retrieve and display tweets in the application. But on a much smaller scale.
Any ideas on how this could be done?
Would be much appreciated.

Simply use the Twitter API to send a Web Service Request accessing those specific tweets in a data friendly format like XML or text. Then simply bind that data to a ListView or whatever pleases you.
I'm trying to write an iOS application that'll get data from a web server and display it as I want. I want to use JSON for this purpose. But as I'm absolutely new to web apps I've got no idea how I'm going to get the url to a certain feed. Now here're the two big questions:
How do I find the url to a feed provided by a web service? Is there a standard way or is it publicly or exclusively handed to the web service subscribers?
Is the format they provide data in up to their preference (like XML or JSON)? I mean, do I choose my data parsing method according to the format the web service gives data in? So that if the feed is in XML format using NSJSONSerialization class makes no sense.
The URL to use is dependent on the web service and is usually well described in the documentation.
The type of data they return and the the structure is also usually well described in the documentation.
The common bits you'll need to know are how to get to the web-service (NSURLRequest/NSURLConnection or any of the many asynchronous wrappers that are open source and available with a bit of searching), And how to deal with the the returned data - whether it's in JSON (NSJSONSerialization, JSONKit) format or XML (NSXMLParser, libxml, or any of the many open source implementations that are available and described with a bit of searching)
I have a web site. This is a drupal site using PostgreSQL database.In this web site we can get direction data from one city to another by going to direction tab and giving start and end location.go to this URL and check that. http://www.zoomsrilanka.com/pathfinder .
direction data is loaded to dashboard. I want export that direction data to a iPhone so that this data can be used another application in the iPhone. If I tell in another words I want to send that data and need to store in a iPhone so that it can be used for another task. I want to know that how to store data in iPhone?
If you have control for the website you mentioned, You can create one webservice which will give you the required data in XML format by accepting parameters from iPhone.
i.e. you can call webservice from iPhone passing parameters and your webservice will provide response to that request in the form of XML and on receiving XML you can parse that and use according to your requirement.
It's not possible to share data between different IPhone applications. Each application has it's own "storage".
You can create API if you have access of server which you mentioned, API should give XML/JSON in response, so iPhone can take this response and parse accordingly, and store structure in sqlite local database.
Is it possible to get (scrape) data from a site that requires logging in using YQL? If yes, please tell the procedure.
You'll need the user to authorize your access via OAuth, as YQL's docs mention. In addition to the docs pointed to by links from the URL I just mentioned, you can learn all about OAuth here, then get libraries to help you use OAuth, depending of course on the programming language you want to use, from the links listed here.
Depending on how the remote site is set up, you could use a simple POST (there is an open data table for that1) or you could create your own small, custom data table and use <execute>2 to send whatever headers (including Cookie:) you need over one or more GET/POST requests.
