Asp Forum - NWS-NOAA: accessing attributes with SOAP4R

Hi Ruby Guru's,

I've successfully retrieved data from the NWS weather server with the
example that was give at the following link:
http://groups.google.com/group/comp.lang.ruby/msg/5fb9a1...

So far so good.

However, I'm only able to get text data, that is the data that's not
part of an XML tag. I did not find a way to access XML attributes.

E.g.: I have no problem to get the 'point1' information, indicated by
<location-key>, but I can find a way to get '

<location>
<location-key>point1</location-key>
<point latitude="38.99" longitude="-77.99" />
</location>
<time-layout time-coordinate="local" summarization="none">
<layout-key>k-p24h-n7-1</layout-key>

The closest I've gotten to see that the data is actually there is by
doing:

p data['location']['point'].__xmlattr

This prints something that lists 'latitude' and 'longitude'. But how do
I access the value itself?

p data['location']['point'].__xmlattr['latitude'] or
p data['location']['point'].latitude

doesn't work.

Any suggestions are greatly appreciated!

Hey,

Well, I'm not an expert (yet:) in Ruby, but I stumbled across the
"extraattr"-attribute of the SOAPElement in the SOAP4R-library.

See http://www.ruby-doc.org/stdlib/libdoc/soap/rdoc/... and
http://wiki.rubyonrails.com/rails/pages/PayPalW... for more
details.

Maybe that'll help you?

Hi Holgi,

Thanks for the pointers. Unfortunately, it seems that I'm dealing with
a SOAP::Mapping:Object instead of a SOAPElement. I'll let you know if I
make any progress.

Quoted from article...

Furthermore, scientists didn't just find ice; they found organic
molecules, similar to what may have started life on Earth, Campins
said.

"This asteroid holds clues to our past and how the solar system and
water on Earth may have originated and it also has clues to our future
with exploration of near-Earth asteroids," Campins told The Associated
Press.

"We're showing that they're wetter than we thought," Campins said.
"We're showing they have organic molecules that might have been the
building blocks of life on Earth."

....all reasons to be excited. How rapidly we have come to know and
begin to understand the granduer of the *cosmic* blueprint. Now if we
could just fire up the LHC and get some results...though I can do
without an earth-centric black hole. That sucks!

I doubt the existence of Earth's personal black hole, but I do think
there might be one at the center of "The Nice Mean Man" - well, at least
an off-white hole...
