Somehow i’m in :heart: with old school stuff and this Nokia LCD is cute and compact!

I have everything hooked up and its working well so the next step is to figure out the webhooks setup so that I can pull in the Air-quality index and view it easily!

Here’s the github repo: https://github.com/kennethlimcp/nokia-iot

So i am trying to extract the data from the dataset here:

<channel>
  <title>PM2.5 Update</title>
  <source>Airviro</source>
  <item>
    <region>
      <id>rNO</id>
      <latitude>1.41803</latitude>
      <longitude>103.82000</longitude>
      <record timestamp="20150919220000">
        <reading type="PM25_RGN_1HR" value="42"/>
      </record>
    </region>
    <region>
      <id>rCE</id>
      <latitude>1.35735</latitude>
      <longitude>103.82000</longitude>
      <record timestamp="20150919220000">
        <reading type="PM25_RGN_1HR" value="43"/>
      </record>
    </region>
    <region>
      <id>rEA</id>
      <latitude>1.35735</latitude>
      <longitude>103.94000</longitude>
      <record timestamp="20150919220000">
        <reading type="PM25_RGN_1HR" value="52"/>
      </record>
    </region>
    <region>
      <id>rWE</id>
      <latitude>1.35735</latitude>
      <longitude>103.70000</longitude>
      <record timestamp="20150919220000">
        <reading type="PM25_RGN_1HR" value="52"/>
      </record>
    </region>
    <region>
      <id>rSO</id>
      <latitude>1.29587</latitude>
      <longitude>103.82000</longitude>
      <record timestamp="20150919220000">
        <reading type="PM25_RGN_1HR" value="57"/>
      </record>
    </region>
  </item>
</channel>

Using a simple .indexOf() search function, i managed to extract information for rNO and rEA (2 hook response from webhook`) but the other 2 data set is missing due to the way i am processing the response.

Any suggestion on how i can extract them efficiently? :smile:

I need the:

  • <id>rNO</id>
  • <reading type="PM25_RGN_1HR" value="42"/> (only the number 42)

breezometer.com has a free API that gives JSON responses so you could use a Response Template and filter down to the exact data you want. No need to extract, just tokenize and reuse the data to display on the screen. I am fan of this method because I am not so good with extract and it culls the data to minimum needed.

@LukeUSMC thanks cool!

But this dataset is from Singapore’s agency and it’s more accurate to the hour. I appreciate your inputs though! :smile:

Fair enough. Here is a XML to JSON proxy service that you could route the call through… :smiley:

Here is another using Google Feed API

If you can’t tell…I am a HUGE fan of JSON and loath XML and the parsing mess it creates! One response, nothing but the data you want and no parsing. Doesn’t get much better than that!
