I have a need to concatenate a list of strings with single characters. I've figured out how to do it but it seems quite ugly. I would welcome any advice on a method I'm missing.

I have a list of strings named "inputs"

To concatenate a single character "<" to the start of every string in the list I first need to create a list of this character with a dynamic length as so:

lth = "".pad(len(inputs),"<").replace("<","<,").left(2*l en(inputs)-1)

Then I can use map to join the two lists of strings elementwise:

joined = map(&strcat,lth,inputs)

Is there a better way of achieving the same result?

I think the approach you've laid out is pretty solid. It is slightly confusing because 'lth' is really a string that you'll be splitting by a comma to get a list back out. I probably would've used a while loop to go through each item in the list and then adding the "<" on, but I'm not sure that'd be cleaner.

You say you have a list of strings. I assume it was initially a comma-separated string? And after you add the "<" to each itme, what do yo plan on doing with the resulting list?

I'm building an extension to the existing XML writing node from LAL so that it is able to handle nested XML tables and associated XML tag attributes. I need to do this to conform to the GML v3 specification.

My natural inclination would have been to use a for loop. Not sure how to loop over a list like this with a while loop. I'm probably just missing the obvious. You are correct that the initial inputs list is generated by splitting on a delimiter. The length of this list can be variable and I then need to add "<" and ">\n" to each end as well as "</" and ">\n" to complete the tag and then add in data within the tag.
