SubC | A Tour Through the SubC Compiler | Parser library

My suggestion about your mistake:

You use it in wrong moment. You click it in every category but you have to click it only when you selecte subcategories.

I needed different ID - dialog-0 instead of dialog-1 and I used shorter XPath.

I see two problems.

First: you try to get all checkboxes before loop but you should get only all categories, next run loop to click category and then search checkboxes for current category, and for every checkbox you should search checked

Second: this page displays non-standard widgets so it doesn't change checked in checkbox but set class in some non-standard widget.

There was also other problem. When I clicked category or checkbox then sometimes it was displaying popup message which was hidding other checkbox and code couldn't check it. I click label which also check checkbox but it doesn't display popup message

In two categories there are subcategories and it still needs code which will click subcategory, get checkboxes and check them. And next it has to click button to go back to categories.

There are many //mat-nav-list - one with categories, one with columns and subcategories and one with columns in subcategory - so I have to use index to work with correct list - and xpath starts indexes at 1 - (//mat-nav-list)[1], (//mat-nav-list)[2]. It needs also ( ) to select correct list because //mat-nav-list[1] and (//mat-nav-list)[1] mean different objects.

Minimal working code:

I guess several issues are here:

1. find_elements_by_css_selector returns a list of web elements. In case there is no match it returns an empty list, but is is still a list, not None.
2. to get the element text, I guess this is what you want, you should apply .text on returned web element
3. You should use try-except and find_element_by_css_selector or getting the first element from list if you are using find_elements_by_css_selector
   So, I think your code should be something like this:

doc.id returns the underlying document ID. You need to first get the current DocumentReference (doc1, doc2), using that get CollectionReference (subC) and then get its parent which is your document1 and document2.

So, you need this:

The command subc mean "subtract a constant" and needs a float or integer argument after it, e.g. the following command would subtract 273.15 from the field contained in temp_in_K.nc and put the result in the output file temp_in_C.nc (note that the meta data is not changed, however):

Unfortunately it won't look pretty either way, as you can't nest into an array if it's undefined part way through.

Try this:

I fixed it myself, here is what I did:
