Reading a XML-file with several attributes

In this sample we read a XML-file with several attributes into Clarion.
This example was written by Trevor Dickson, Capetown, ZA.
I added some comments and icons, you can download the entire folder here.

In a simple xml file with clearer names, the order of the variables in your group or queue doesnt really matter that much, but in this case the order is crucial and it seems you need to define all the fields, although you only may need some, else the order goes out.

Here you see the XML-file which is received:

  <aws:weather xmlns:aws="http://www.aws.com/aws">
    <aws:api version="2.0" />
    <aws:WebURL>http://weather.weatherbug.com/Canada/Wiarton-weather.html?ZCode=Z5546&Units=1&stat=CYVV</aws:WebURL>
    <aws:InputLocationURL>http://weather.weatherbug.com/Canada/Wiarton-weather.html?ZCode=Z5546&Units=1</aws:InputLocationURL>
    <aws:station requestedID="" id="CYVV" name="Wiarton Airport"
    city="Wiarton" state="Canada" citycode="CYVV" country="Canada"
    latitude="44.75" longitude="-81.0999984741211" />
    <aws:current-condition icon="http://deskwx.weatherbug.com/images/Forecast/icons/cond001.gif">Cloudy</aws:current-condition>
    <aws:temp units="°C">15.0</aws:temp>
    <aws:rain-today units="mm">0.00</aws:rain-today>
    <aws:wind-speed units="km/h">13</aws:wind-speed>
    <aws:wind-direction>S</aws:wind-direction>
    <aws:gust-speed units="km/h">14</aws:gust-speed>
    <aws:gust-direction>SE</aws:gust-direction>
  </aws:weather>

From the capesoft xfiles docs:
Notice also that the order of the fields is critical. Without the ability to match exclusively on the name, xFiles will take the order of the fields into account. Lastly notice that the attribute comes before the field. so the Type comes before the Price.

So in our case, the units will become before each weather description, e.g. Units and then Temp, Units and then Windspeed, etc Last thing to remember is that xml is case sensitive and to use the external name field

ResultGroup (GROUP)

   result:api
   result:weburl

   result:tempunits               -> units first                 External Name: units
   result:temp                                             -> temperature after units     External Name: aws:temp
   result:rainunits             -> again units first           External Name: units
   result:raintoday                                        -> rain-today after units      External Name: aws:rain-today
   result:windspeedunits
   result:windspeed
   result:gustspeedunits
   result:gustspeed
   result:gustdirection

Thats mostly all! Add salt and pepper as you like....
