From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You’re right I was calling the array wrong! I still couldn’t get it to work with the other method though
While I do agree that bash isn't really the best tool for the job when working with XML data, there is a simple enough solution.
$ read -r -a arraytest <<< "2023-06-19T00:00:00+01:00 2023-06-18T00:00:00+01:00 2023-06-17T00:00:00+01:00 2023-06-16T00:00:00+01:00 2023-06-15T00:00:00+01:00 2023-06-14T00:00:00+01:00 2023-06-13T00:00:00+01:00 2023-06-10T00:00:00+01:00 2023-06-03T00:00:00+01:00 2023-05-31T00:00:00+01:00 2023-05-27T00:00:00+01:00"
$ for ds in "${arraytest[@]}"; do echo "$ds"; done;
Using Bash for this when source data is XML is simply wrong. It's not the right tool for the job. You should consider learning basics of Python, which you could use to work with the source data.
Unless you already know how to do that in Python, and are simply interested in figuring out how to do that in Bash, in which case godspeed to you.
Thanks I’ll look into that, I was trying to use bash because I can’t really install anything on this server, but it looks like it already has python installed
I need them as an array so that I can use them in a for loop
I don't think you need an array then. Arrays are very cool but in general the default IFS for bash loop is a space already

If you really need an array
$ arr=(`your_xmlstarlet_command`)
$ echo ${arr[0]}
2023-06-19T00:00:00+01:00
$ echo ${arr[1]}
2023-06-18T00:00:00+01:00
$ for D in ${arr[@]}; do echo "begin - $D - end"; done

And just for completeness, when you are changing IFS good idea is to save it in OLDIFS and reset it after the loop. IFS is a special veriable and changing it changes how bash interprets the character it contains
OLDIFS=$IFS
IFS=$'\n' # when you want to pass a list separated with newlines instead of spaces
for ELEMENT in <list of elements separated with \n>; do <your commands>; done
IFS=$OLDIFS
I managed to get it to work in the end but thanks for this, I’ll remember that for next time
What exactly is your end goal? There might be other utilities that can get you to your wanted solution easier. I, the same as learnbyexample, did not have the problem.

Are you sure it's not working? Does echo ${arr[@]} return the whole array? Does echo ${arr[1]} return the second value? I think just echoing $arr without specifying an index returns only the first value.
You’re right I was calling the array wrong! The arr=($line) method seems to work although I still couldn’t get the read method to work
