metaf2xml can download, parse and decode aviation routine weather reports (METAR, SPECI, SAO), aerodrome forecasts (TAF), synoptic observations (SYNOP), observations from buoys (BUOY) and meteorological reports from aircrafts (AMDAR).

It also provides XSLT style sheets to convert the XML to plain language (text, HTML), or XML with different schemas
