    Just wondered if anyone has tried reading data from a web site like the BOM.

    http://www.bom.gov.au/products/IDN60901/IDN60901.94759.shtml

    Any ideas on the most effective way to do this? Is there a way to grab the source of the page (and then it could be parsed).

    I am after the 1/2 hourly updates which come in the form:

    11/02:30pm 28.0 29.8 20.3 63 5.1 ENE 11 19 6 10 - 0.0

    Any suggestions most welcome!

    Thanks

    Andrew

    Thanks for the feedback but I'm after the specific half hourly data for the Terrey Hills weather station. I don't think this is placed on the ftp site (at least that frequently).

    The only other formats for weather OBSERVATIONS (not forecasts) that the BOM gives out for the data you want, (other than paid versions), for Terrey Hills, is the following:

    Comma delimited format used in spreadsheet applications
    http://www.bom.gov.au/fwo/IDN60901/IDN60901.94759.axf

    JavaScript Object Notation format (JSON) in row-major order
    http://www.bom.gov.au/fwo/IDN60901/IDN60901.94759.json

    JavaScript Object Notation format (JSON) in column-major order
    http://www.bom.gov.au/fwo/IDN60901/IDN60901.94759.jsn

    I would assume that the comma delimited format will most likely be the most use to you.

    Many thanks. Missed that one. Obvious when one looks at the bottom of the Terrey Hills page...!

    Would I be pushing my luck to ask for suggestions on how to automate the download of the file? I have Homegate and a PAC.

    Be careful. Any solution you come up with is then at the mercy of the BOM changing their web site / URL / file format... whatever.
