//============================================================================
// DEPENDENCIES:
// - It requires the class "xmlParser" (Be lucky: Also in the Archive file!)
//============================================================================
// DESCRIPTION:
// This Class gets Weather RSS from WEATHER.YAHOO.COM and parses it into
// a weather object with usable attributes. Use it for:
//
// - Actual Situation (temperature/sunrise/sunset/Image...)
// - Forecast Day 1 (temp low, high/text/date/day/image...)
// - Forecast Day 2 (temp low, high/text/date/day/image...)
// - Forecast Day 3 (temp low, high/text/date/day/image...)
// - Forecast Day 4 (temp low, high/text/date/day/image...)
// - Forecast Day 5 (temp low, high/text/date/day/image...)
//
// PUBLIC METHODS
// - parse() : Gets the XML File parses it and fills attributes
// - parsecahed() : Quicker!!! Writes a cached version to a local
// file with expiry date! expiry date is calculated
// with the given input parameter
//
//============================================================================
// SAMPLE:
// - See the file "weather.test.php" in this archive for Santiago de Chile
//
// WEB GUI URL: http://weather.yahoo.com/forecast/CIXX0020_c.html?force_units=1
// RSS URL: http://xml.weather.yahoo.com/forecastrss?u=C&p=CIXX0020
//
// The class needs one Attribute in the Constructor Method:
//
// $weather_chile = new weather("CIXX0020", 60);
//
// "CIXX0020" is the Yahoo code for Santiago de Chile. See WEB GUI URL above!
//
// "60" means 60 seconds until the cache expires. If not needed set = 0.
//
// GO TO WEATHER.YAHOO.COM and search for your desired weather location. If
// found, click on the location link (must see the forecast). Now take
// the code from the URL in your browsers address field.
//
//============================================================================
// Changes:
// - 19.11.2005 MAV : XML Feed Structure from Yahoo changed. Adapted script.
