Hi guys,

i have tried to read out this page per http request  
"[Bad Schallerbach - GEM2GO WEB - Zentrum - Bürger\<br\>service - Abfall & Entsorgung - Abfalltermine](https://www.bad-schallerbach.at/system/web/kalender.aspx?sprache=1&menuonr=226753868&typids=226758838,226758840,226758842,226758844)"

But the information about the schedule is not included in the request answer - maybe it will be cut off?!

Is there another way, to get this information?

Thanks guys!

OK - with the HTML Parser i can see the information in de Debug menu.

My problem is now, that i cant get the right information. maybe because of the cookie query.

I have the correct link in node red but in the debug i get information from the wrong street, also because of the cookie problem i think.

These are the information i get:

To get more responses for help it would be best to capture the html page, then construct a sample flow with your html node and selectors you have tried, put the captured http request info in an inject node or template node. Also supply what info you are trying to extract, may be highlight it in a screenshot. This means others then can test and will know what info you are trying to extract.

You need to capture the request returned payload, as a login is required. No one can see the returned payload in full so can not see the source.  
save the return payload of the request node to file using a file write node, then upload here so we can see the source.

This is the page(with no styling) your http request node returns for me, there is no table like the image you show

Sorry, that was my bad. I marked the worng infromation  
I would like to know when the garbage is picked up - not the opening hours of the municipality

There is no login necessary. The page looks like this:

You have to choose a street and a housenumber to see the schedule.

I get the same reqeust as you - from my debug node.

Thats the sourcecode of the page:

That is not what is being returned form the http request, all i get is what i posted above, I think you will find that there is a separte javascript call to another url to return the table data, you will need to look in the developers tool in browser to find the correct url needed.  
Once you find the correct url that returns the table the selector would be `td.td_kal`

I couldnt figure out either how the page requests that data ..  
an alternative is to use a module called Puppeteer .. a tool based on Cromium browser that can accept commands programmatically .. mostly used for website functionality testing

We can use this npm module in a Function node ( [functionExternalModules](https://nodered.org/docs/user-guide/writing-functions#using-the-functionexternalmodules-option) )

**Test Flow:**

```auto

You are running an older version of Nodejs that is not supported by the module  
Since you are on a PI you can run the official installation [script](https://nodered.org/docs/getting-started/raspberrypi) with the `--node14` parameter to update to a compatible version

`bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered) --node14`

What you see in your browser is the html and JS and the browser runs the JS and updates the source and displays it..

The http request node does not run the JS, therefore the output does not have the returned ddata from any of the JS code.

@UnborN flow should do the trick as it can run the JS.

ok .. one thing at a time ...

`sudo systemctl disable nodered.service`  
to disable the service until we figure whats wrong with that

run  
`which node-red`  
show us the result

also run  
`node-red`  
does it start manually ? show us the log ..

Starting Nodered manually was successful

I have used your mentioned cmd a 2nd time and now it seems to be working.  
I can start it as a service and and autostart should now work again

ok .. the problem is that your node red is installed under **nvm**?  
which stands for Node Version Manager which is known to cause problems when running with node-red and updating with the official script.  
I would recommend removing NVM ([instructions here](https://github.com/nvm-sh/nvm/issues/298)) but first **make a backup of your flows** and any related files from `/home/pi/.node-red/`  
Then re-run the script to install NR properly.

regarding puppeteer .. i tried several things on my PI but i couldnt get cromium to run .. seems to be an issue .. i'll keep reading for a solution .. if there is one

> I couldnt figure out either how the page requests that data ..

Need to set/accept a cookie first, same issue will exist with puppeteer.
