save some information from a xml or json to a txt file

gismo2006

oh sorry i forgett, to describe. I have several bash scripts. For a example an bash script which display time an other one which display date. Now I have create a module for myself using the Hotword module by alexya. It works perfect. When i say “aktuellesDatum” (in englich actuellDate) my mirror says In german “Today is the 20. October 2016” for example. The same at the timescript.
Then I have (I thing you as a good coder like to kill mke :-D ) a php script on my own webserver who runs at start up (I use cronjob) to read out the rss feed of the german website “Tageschschau” (A news site") and write the header in a txt file. Then the txst file is automaticly copied in in my own modulefolder. Then I write a module for myself again, using hotword detection again. If I now say “Aktuelle Nachrichten” (Actually News) My mirror reads out loudly the TXT file. (before it will read out my mirror create an acutell txt file ,whit the newest news)

So I haven’t to look at the mirror, maybe durring take a shower in the morning. (Every day the same, I haven’t enough time in the morning :-D ) or something else i will inform about actually news, time or edate. I have tested several tts but the best for me was pico2wav. And a feature i added at this way too, was to read out loud the ip adress of the mirror. So I can simple control the pi if my monitor didn’t work. (save shut down for example).

AND NOW. the thing i need this txt file I asked for. I like to do the same whit a little weather sentences about the actuall weather. In the json or xml file which I have was written Wolkig (cloudly) and in an other tag the temp. If I have finisched this I like to say “AktuellesWetter” (actuaklly weather) and my mirror says “10 °C, wolkig” So I will know very fast what clothes I need and (for example) I need a umbrella.

Now you like to say maybe, “you write you read out the feeds of the Tagesschau feed. Why do you not use this for the txt you like too?” I will answer I have test it but it didn’t work.

Hey @gismo2006,
I think i can help you. As i started to develop MMM-DWD-WarnWeather, i used a little Pythonscript to explore the API. So if Python would be ok for you, just explain what Data should be written to your Text file and i can modify the Script for you.

@LukeCodewalker Hi, YEAH! THANK YOU! Python will be OK for me. I have tested a python script, that I found at the www. Lat days. But it didn’t work. Late today if I have some time I will post some more information OK?

Here some more information:

I use this link to use the api (It the same website which is use for the default Weather modul)

http://api.openweathermap.org/data/2.5/weather?id=2934486&lang=de&units=metric&mode=xml&appid=

(I only cut out my api key at he end)

This link create a xml file (You can change into json, simply erase xml in the link and put json there)

This xml looks like this:

DE

And, I only like that your python script read out the line till and if it possible the line <temperature, too. And the save this in a txt file.

That will be great.

And if I can a have little bit more of your time it will be possible the txt file can use the following "Today it is and .

It would be perfekt. But that I can took later by learning myself. If your python script can read out the xml file and save in a txt file it will be great.

@gismo2006 here it is. just place your app id and the path of the file, where the text should go.

import json
import subprocess

APP_ID = ''
FILE_PATH = 'test.txt'

url = 'http://api.openweathermap.org/data/2.5/weather?id=2934486&lang=de&units=metric&mode=json&appid=' + APP_ID
curl_req = 'curl -L ' + '"' + url + '"'
p = subprocess.Popen(curl_req, stdout=subprocess.PIPE, shell=True)
(output, err) = p.communicate()  
p_status = p.wait()

try:
    decoded = json.loads(output)
    weather = decoded['weather'][0]['description']
    temp = decoded['main']['temp']
    f = open(FILE_PATH,'w')
    f.write('Today is ' + weather + ' and ' + str(temp) + ' degrees.')
    f.close()
except (ValueError, KeyError, TypeError):
    pass

Hi, thank you for the code. But there was a little misstake I think. I have copied your code and save. put in my api and the right folder.

then the first try. All works fine the code generate a test.txt file. But then I oen the txt file it was empty.
Ok I think maybe I put in something wrong. But everything was ok.

At a second try I chnage the folder name, because I think maybe the was some folder Rights or something else. But the same. The txt file was empty.

At my next try I cut of the f.write line and there was only written f.write(‘Today is’)
And I see everything work like it should. In the txt file was written Today is. Now I put some more in this line again. Everything works fine till I put the word weather. If I put this the txt file will be empty.

I like to try something mor later today. But I want give you a feedback. And I like to say thank you.

Sorry I forgett there was no error. Also Python displays no error if I try it a the Python IDLE.

LukeCodewalker

@gismo2006 I think I got the problem. The german description can contain letters like äöü etc. i will fix that later when i’m at home.

Now it should work
