    weather-metar: properly extract metar data
    
    Commit 283afc2d23355def1c1bab70a641f40cea52ba7f switched to new
    METAR data provider, but did not fully update code to properly
    extract METAR data.
    
    The code still assumes that data are separated by newlines. That
    means that now extracted data includes part of opening raw_text
    tag, location code and closing raw_text tag.
    
    Fix this by moving pointer to correct position to make sure that
    xml tag and location code is not included. Also search for
    closing tag to exclude it from data.
