NewsSearch - perform a Yahoo News Search
This class implements the News Search web service APIs. Allowed
parameters are:
query - The query to search for.
type - The kind of search to submit:
* "all" returns results with all query terms.
* "any" resturns results with one or more of the
query terms.
* "phrase" returns results containing the query
terms as a phrase.
results - The number of results to return (1-50).
start - The starting result position to return (1-based).
The finishing position (start + results - 1) cannot
exceed 1000.
sort - Sort articles by relevance ('rank') or most-recent
('date'). Default is by relevance.
language - The language the results are written in.
site - A domain to restrict your searches to (e.g.
www.yahoo.com). You may submit up to 30 values
(e.g. ["www.yahoo.com", "www.cnn.com"]).
output - The format for the output result. If json or php is
requested, the result is not XML parseable, so we
will simply return the "raw" string.
callback - The name of the callback function to wrap around
the JSON data.

Methods inherited from yahoo.search._Search:
- __getattr__(self, name)
- __init__(self, app_id, opener=None, xml_parser=None, result_factory=None, debug_level=0, **args)
- The app_id is a required argument, the Yahoo search services will
not accept requests without a proper app_id. A valid app_id is a
combination of 8 - 40 characters, matching the regexp
"^[a-zA-Z0-9 _()\[\]*+\-=,.:\\@]{8,40}$"
Please visit http://developer.yahoo.net/search/ to request an App ID
for your own software or application.
Four optional arguments can also be passed to the constructor:
opener - Opener for urllib2
xml_parser - Function to parse XML (default: minidom)
result_factory - Result factory class (default: none)
debug_devel - Debug level (if any)
All other "named" arguments are passed into as a dictionary to the
set_params() method.
The result factory is specific to the particular web service used,
e.g. the different Yahoo Search services will each implement their
own factory class.
Both of these settings can be controlled via their respective
install method (see below).
- __setattr__(self, name, value)
- # Implement the attribute handlers, to avoid confusion
- encode_params(self)
- URL encode the list of parameter values.
- get_param(self, param)
- Get the value of a query parameter, or the default value if unset
- get_results(self, stream=None, xml_parser=None, close=True)
- Read the stream (if provided) and either return the raw XML, or
send the data to the provided XML parser for further processing.
If no stream is provided, it will call the open() method using the
default opener. The stream will be closed upon return from this
method, unless the close=False is passed as an argument.
- get_url(self, with_params=True)
- Return the URL for this request object
- get_valid_params(self)
- Return a list of all valid parameters for this search
- install_opener(self, opener)
- Install a URL opener (for use with urllib2), overriding the
default opener. This is rarely required.
- install_result_factory(self, result_factory)
- Install a python class (not an instance!) that should be used as a
factory for creating result(s) objects.
- install_xml_parser(self, xml_parser)
- Install an XML parser that will be used for all results for this
object. The parser is expected to "read" the data from the supplied
stream argument. To uninstall the parser (e.g. to make sure we
return raw XML data) simply call this method with an argument of
None.
- missing_params(self)
- Validate that the search object is propertly setup with all
required parameters etc. This is called automatically before a
search is actually performed, but you can also call it manually
if desired. It will return a list of zero or more paramters that
are missing.
- open(self, opener=None, retries=2)
- Open a connection to the webservice server, and request the URL.
The return value is a "stream", which can be read calling the
read(), readline() or readlines() methods. If you override this
method, please make sure to call the missing_params() method before
you try to send a request to the Web server.
- parse_results(self, xml=None)
- Get the result from the request, and instantiate the appropriate
result class. This class will be populated with all the data from
the XML object.
- reset(self)
- Reset all the parameter values for the object instance.
- set_param(self, param, value)
- Set the value of a query parameter
- set_params(self, args)
- Set one or several query parameters from a dictionary
