Basic requests

Sieve requests begin as JSON objects with the following layout:

{
    "url" : "https://api.github.com/repos/alexose/sieve/commits",
    "selector" : ".commit .date"
}

By default, Sieve uses the JSONSelect engine. If your target URL doesn't return raw JSON, however, you can specify other selector engines:

{
    "url" : "http://google.com/finance",
    "selector" : "//td[@class='price']",
    "engine" : "xpath"
};

You can run this request from your node application like so:

sieve.get(request, function(result){
    console.log(result);
});

Which will log the following data to the console:

{
    "result":[
        "2014-02-12T18:19:31Z",
        "2014-02-12T18:19:31Z",
        "2014-02-12T15:36:45Z",
        "2014-02-12T15:36:45Z",
        "2014-02-12T15:00:53Z"
    ]
}
