Hi,

I have a json feed that I would like to extract information out from but for the last few days I've been struggling. I can target the item using the key but because the number of items in the object can vary which obviously then breaks my method.

E.g

Code:
var dayone1260 = data.SiteRep.DV.Location.Period[0].Rep[0];
      console.log(dayone1260.Pp);
My Json feed looks like this:
Code:
<DV dataDate="2012-11-01T18:00:00Z" type="Forecast">
<Location i="310069" lat="50.7179" lon="-3.5327" name="EXETER" country="ENGLAND" continent="EUROPE">

Is there a better way to obtain the .Pp value in a variable so I can then use / display it on the page. Using the 'value' of <Rep>?

My javascript knowledge is limited to jquery front end stuff to date so sorry if I've not explained this very well.
