It would be better to use Simple XML's methods to navigate through the data, rather than treating it as arrays. But if you really have to, I'll show it below.

I generally recommend using foreach rather than for to loop over arrays. But if you're going to use a for loop with array indexes, they should be based on the count() of the same array you're indexing into. It doesn't make sense to use count($array) and then use that to index into $array[2]['row'] -- you should use count($array[2]['row']).

I'm not sure where you're getting $array[2] from in your code. The top-level array doesn't have any numbered indexes, it's an associative array. Numbered indexes aren't used until you get to the row and column elements nested deep within.

This question is very broad and it is unclear what “specifically” you are asking. From your comment… ”JUST TELL ME AN ALGORITHM” … is not really possible. No algorithm will fit all situations. Without specific details a “general” algorithm may be present, however it would still lack specifics that would be different depending on the context in which it is used in.

For starters I am only guessing that you MUST use PowerShell for this or PowerShell is what you are most familiar with. This can definitely be done in PowerShell, however depending on the environment you code in, using PowerShell IMHO is going to make this much more difficult.

I am just saying that IMHO, this would be much easier using an IDE like Visual Studio with C# or VB. I am guessing there may be other options, but an IDE that helps with errors is going to be crucial and from my limited PowerShell experience, help with errors is fairly non-existent. I am not trying to dissuade you from using PowerShell and my opinion is clearly based from a NON-PowerShell user. I am just saying that I do not use PowerShell much and I had a difficult time trying to help here using PowerShell.

Getting off my soap box, I can say that there are a couple things that I found that may be causing you some problems when trying to bind a data source to the grid.

To begin, in the posted code under the “2nd. Working with bounded DGV.” Header section, there are two lines of code…

First of all, we need to improve your design.

1. The factory pattern makes sense only if you are coding to abstraction, which means, the factory should create the concrete type, but you should not know the concrete type but only the abstract type. This is not the case in your design. You say that you are using abstract factory pattern, but you cast the created object to Circle, which is "coding to implementation".

2. The Compiler both compiles the lines to Shapes, and executes them. A compiler should only transform text (code) into an executable object, and should not execute them. Unfortunately, with your current design, it is not possible to pass the created shapes into the output form and have them drawn.

3. You need to pass all the compiled Shapes into your output form, and should draw in OnPaint override where the run-time is re-drawing the surface of the Control (form)

The abstraction (Shape):

If your code compiles well, then consider adding escape character to show the new line character inline with your textbox area. So instead of "\n" use "\\n".

Here is the working example.

It is explicitly modelled on the Python range function. The precedent for prefixing a was that in Python 1 there was already a variant of range called xrange.

I think it should be

You are constructing HTML as a single long line.

Outlook has some issue with line length and it inserts a new line after a certain amount of characters. This new line causes such gaps in words. Sometimes it is inserted not inside the word and it is being displayed good then.

The solution is to insert line brakes between HTML tags. Like this:

Modify following code

As far as I know there isn't a flatten method for tuples (unless you use shapeless), so the map might not look very appetizing:
