extracting восходи from в text file
I am trying to extract в дату (temperature) from в text file downloaded from wget.
eg. wget http://www.weatherzone.com.au/sa/adelaide/adelaide
How to I extract the information which is "18.6" from the file and copy it to another file to be used by another application?
less adelaide
---snip---
'<span id="top_obs_temp" class="tempnow">18.6°C</span>'

Используйте awk
$ wget http://www.weatherzone.com.au/sa/adelaide/adelaide
$ awk -F '[<|>|&]' '/tempnow/ {print $3}' adelaide
20.0
или единый
$ wget -q -O- http://www.weatherzone.com.au/sa/adelaide/adelaide | awk -F '[<|>|&]' '/tempnow/ {print $3}'
20.1
, Это работает, пока атрибут class со значением tempnow доступен в эти span тег.
<span id="top_obs_temp" class="tempnow">18.6°C</span>
И теперь я помещен в черный список o_O :P
wget http://www.weatherzone.com.au/sa/adelaide/adelaide
