Is it possible to generate a XMLElement by using part of the code to be generated with a string, or are the only methods a strict use of AddAttribute and AddChild?

Hope the code below explains what I mean. The first line is a strict copy of a declaration in the help file.

The question is if I could use some part of the definition which is saved in the str variable and combine it into the first declaration?

The member command allows testing, if a value is in a table.

But is it possible to check if the index is used, not the value?

I'd like to generate a string where the first part is changeable, and the second one needs to include apostrophs.

The section until til left bracket can be stored in one variable, but how can I add "allmembers") into the string?

Here's a possible bug in ExcelTools.

When importing from an Excel file, Maple drops text which is referenced from a different sheet. That does not apply to numbers.

Any ideas why the attached package won't install?

We've been using Maple Cloud previously, but that doesn't work anymore apparently (same problem as stated here, https://www.mapleprimes.com/questions/226154-Installing-Packages-From-The-Cloud-Hangs, support case filed previously).

But I can't even get it installed manually either.
