Read XML with GET Object

[StingRay]

Hi!

is there a way to read a xml-file with the get object? the main problem is, i think,
that in a xml file every unit is called the same. example:

http://www.google.de/ig/api?weather=New%20York&hl=us

you'll get an xml file with forecast conditions for different days. but every high temperature data
for every day is called:

<high data="28"/>

how can i figure out, if it is for the first day or the third? it makes parsing really hard, i think.

Hmm...

<forecast_conditions>
<day_of_week data="Di."/>
<low data="21"/>
<high data="28"/>
<icon data="/ig/images/weather/mostly_sunny.gif"/>
<condition data="Meist sonnig"/>
</forecast_conditions>

So that's a day...

I'd use string parser, set </forecast_conditions> as the delimiter, then each day will come out as a different element you can grab from the 'List Tokenizing' menu from the parser's expressions menu. You could then grab the two characters that follow 'high data ="' using the 'find string in string' and 'extract middle substring' functions.

great idea - and so easy thank you!!

i hope it works now, because i run into some xcode sigbrt error with the use of string parser some months ago.

Glad you found it easy! I was worried I hadn't explained it clear enough. Delimiters are the only way I can think of splitting them at the moment, not without some kind of insane character-by-character fastloop anyway, lol.

ok - very strange happend:

- on windows it works like a charm.
- on ios simulator it shows received text: "unsupported api"
- on ios device (iphone4) it crashes. exit code 0. sigbrt error. (EDIT: This just happens because i've forgot to add 'run this event once' at 'on get complete') --> It now shows "unsupported API" too.

i dont use stringparser at the moment, just 3 GET objects with some events:

Mid$(Received$( "Get object weather" ), Find(Received$( "Get object weather" ), "<condition data=", 1)+17, Find(Received$( "Get object weather" ), "/><temp_f", 1)-Find(Received$( "Get object weather" ), "<condition data=", 1)-18)

to get the actual temperature. hmm. too bad. is this one part of the fight GOOGLE vs. APPLE?!?

Course not, they must have some kind of htaccess blocking mobile devices from reading the xml or something.
