You still have 2 invocations of awk when you only need 1 and you still have too many braces in your 2nd awk script. Try changing:
to:
It should give you exactly the same results with a single awk instead of two awks piped together.

I've been wanting to merge the two awks into one, but have not been successful. This code does not make the program run as intended. It just gives a splash of ongoing text from the xml file.
The reason I used two awks is because the xml file has text that is all broken up between lines; I needed first to concatenate those lines into one line (only the ones of the key phrase), and then that line is easy to edit in the second awk; else, I would be having to edit one line of text between several lines, and that is beyond my knowledge at this point. If there is a way to first do one task (concatenate the text), and then do another (the rest of the text manipulation with that concatenated text), that would be great. I've tried several variations and have not been successful.
Untested: Instead of printf $0 in the first awk script, concatenate $0 to a working variable, like WRK = WRK " " $0, then assign WRK back to $0 for the further processing.
Untested, and a hint only: Methinks replacing the above five lines with
yields the same result. Same might be true for other opportunitites.

Did you figure out what needs to be done based on what RudiC suggested, or do you still need help completing it?

Works perfectly!

Hmmm, a 5:1 reduction in code-not bad.

Though atm, I do need help with using an array/variable in SUB. Rudi had pointed out in post #4 https://www.unix.com/303013671-post4.html a working solution which involved this, but I just could not break it down and make it execute properly:
I am trying to use an array of strings/variables (which is working fine) to insert into sub and be replaced (which is not working):
Yes, above. I've been reading the GNU Awk User's Guide (The GNU Awk User’s Guide), so I haven't been doing as much coding.
I'm very happy that you got this to work for you.
But, please stop trying to hide the logic in your code! Make it obvious. Change:

It isn't immediately obvious what isn't working in this example and you don't give us any indication of what you think it is doing wrong.
The call to split() could be rewritten more simply as:
and always give you identical results. Given that vkeySepA has been defined to be an empty string in your earlier code and assuming that it still is when you ran this, one might note that the call above would return 1 (not the 2 that you seem to be assuming). But since unassigned array elements (like any other unassigned variables) will have a 0 value if used as a number or an empty string value if used as a string, that won't make any difference in this case. Your calls to sub() with those array values should change the first occurrence of the string <orth> in $0 to an empty string.
Note that the <space> after <orth> will be treated as a field separator, not as part of the string to be replaced. Note also that with many of your search patterns (many of which contain <space>s) and replacement patterns (many of which contain <space>s), using code like the above will give you more than 2 fields in the created array unless you use a different array element separator and add an ERE to your split() call specifying the character(s) in your separator as the element separator.

Was not intentional. Just a thing of habit.

Yes, I have to be more clear. I got it working though. It was a silly mistake of not watching the correct text that I was replacing; it was actually working all along.

Yes, found this to be the case. And I've decided to keep the code as it was for now-this is a little too deep for me atm and not entirely necessary for the program to work... As for the other code, I've shortened it up abit.
Just a note: I've started to make this program in C++; it seems that it could benefit from the speed and features. Already, the C++ program can open a file and extract, replace, and print a few text combinations; so you may not see me posting for a little bit in the Shell Programming Forum, but I will still be using awk for the many things that it can do!
