From the call to an api endpoint, I get the following array of nested objects, which is a directory tree

Essentially, I'm struggling with the same XSLT problem as another questioner asking on this site, namely the user "bigsky" in a post of 2013 (s. Trim white-spaces at the end of lines only before a specific tag). But in spite of a useful hint (in the answer of Sperberg-McQueen), I couldn't figure out a satisfying solution for the issue.
What I'm trying to do is, transforming an XML file into a readable HTML document, to create a running "body" text and recombine at line breaks the strings of words divided, that is interrupted by an element, in my original document - but recombine them without whitespaces!
Having played around with several templates in my XSLT stylesheet, I defined one - following the hint of the post mentioned above - to process all nodes preceding a element, and I tried to remove their leading and trailing whitespaces making use of the normalize-space() function, so that the strings preceding and following the specified nodes should be concatenated in the output.
Now, for the most part of the cases, I've actually got the output I desired - however, in some places appears (to my surprise) whitespace before the re-concatenated string, which has no counterpart in my XML file and which I would like to get rid of.

As the relevant files deal with a document of a certain length, I'll show you only extracts of the code - but I'll include parts where the transformation works as wanted, as well as parts where the transformation produces unexpected whitespace.
Concerning the text document at issue, just a brief note for your information: The XML file covers the text of a medieval Latin manuscript according to conventions of the Text Encoding Initiative (TEI) and is, among other things, intended to record palaeographic features of the manuscript (- in case you wonder about the tags/elements I've used). Actually, I'd like to ask you to have a look primarily at the sections around the elements and ignore the details of my text encoding - but at the same time I wanted to show you the selected passages as they appear in my edition (not least because I'm unsure as to the role of adjacent elements ...).

--> Extract from the XML file:

so i am trying to create a list, whereby a list is displaying many items, and two of the items are expandable, and expanding them shows more items(subitems). I have managed to display the list, and the sub-lists, however, clicking either one of the expandable items, expands both items and not just the single one i clicked.

So firstly, i have seperated the listItems as a data structure where i can retrieve them. This is the list Items:

I am struggling with styles in TKinter My main problem is that you cannot click anything in the treeview.

To test, simply press the "Press To Test" Button

For some reason it looks like, style.theme_create takes over my treeview widget, and no matter what I try, I cannot seem to find a solution around it. I tried activating the cursor, selection_set, focus_set, etc.

If I comment the style I can click, but not with it on.

I am still quite new to python and would appreciate some insight.

I tried the t1.bind('') and tried to find a selected style but can't seem to make it work, the bind on its own doesn't work. I've read the documentation but all i've tried related to the selection seems to fail.

I have narrowed down a bug in my program to the following.

The following loop works so long as maxlayout equals 1 but if it equals two thus making the loop run twice then the original values erase.

so if the loop is run once then mainArray.tilef0 will equal tile.empty but if tan twice then mainArray.tilef0 will be undefined and mainArray.tilef1 will equal tile.empty

The same is true for the rest of the properties such as terrain and solid.

My XML files have TEI milestone elements like

:

However, this only returns the text node(s) following the final milestone in the text, and only in the for-each iteration that selects for the attribute value matching that final milestone. I've surely got the >> statement wrong and would be grateful for any advice either with this approach or for a different, grouping-based approach.

I should probably mention that once I've mastered this concatenation, I'll have to add any addition-type content (i.e. revisions by hands not matching that of the current stint) into the equation, by excluding nonmatching content of this nature and including matching content situated within nonmatching scribal stints, but I don't necessarily foresee this having to be added to the concatenation in the "correct" place. I thus should be able to account for these in two fairly straightforward additional steps, but the initial concatenation or grouping solution has to allow for the exclusion of nodes with nonmatching attribute values, and of any other elements I may wish to exclude (e.g. in the below example).

Here is a mock XML file:

I want to code this but I am stuck

So suppose we have a grammar

I tried to create a simple GUI with one check button and one normal button.

The goal of the program is simple:

• if you check or uncheck the check button the normal button should go into disabled mode

What went wrong?

• at first I started to get errors like “AttributeError: 'NoneType' object has no attribute 'config'” I said to myself what “NoneType” object?

• Then I discovered that my Button object right after its creation disappears somewhere (I create it on line 16 and on line 17 I get None when I try to retrieve it).

• is it normal behavior or am I doing something terribly wrong? Or is there another way how to retrieve the button instance and work with it?

The weird thing is that the object still displays on the screen:

My main script:

I am using multiple versions of PowerShell, but only 2 can find all standard commands (or is it commandlets?).

The original install is Windows PowerShell v5.1, but then I also have PowerShell Core (pwsh.exe) v6.1.1 installed.

The problem is that I am trying to run some firewall-related stuff in PowerShell Core, but the Get-NetFirewallProfile command cannot be found.
