sed and $RANDOM in bash script

hello world,

This script seems to not function in several areas. The value of $myrandom does not expand where I want in the see commands near the bottom. Originally I had each line in single quotes and the variable in soignée quotes as well, but that didn't work. I've tried many combinations of quotes and escaping characters but to no avail.

The idea is if one or more than one .xml files exist in the zzzzzz directory, for the scripts to:
come up with a random number,
use the filename before the first "-" and get rid of the path (this works)
go do the sed stuff
then do the stuff under the seds.

the $myrandom is the issue, where the value is not written in the file for the SPS, PROC, and RP lines.

If I can get that working I should be a lot closer than I am now.....

Any help would be appreciated.
for i in /zzzzzz/*.xml

if [ -e $i ]; then

echo $myrandom

patID1=$(echo $i | cut -f1 -d'-')
PATID=$(basename $patID1)

Hello hypervisor, I'd make a few changes to the sed lines, for example this one:

sed -i "" -e "s/<attr tag='"00400009"'>SPS-1234<\/attr>/<attr tag='"00400009"'>SPS-$myrandom<\/attr>/" $i

Open in new window

I'd change to:

sed -i -e "s/<attr tag='\"00400009\"'>SPS-1234<\/attr>/<attr tag='\"00400009\"'>SPS-$myrandom<\/attr>/" $i

I've been testing with these changes, $myrandom is substituted just fine and the in place editing (-i) is working as well. Please test this and let me know what else goes wrong, if any. How is your RANDOM filled btw? I don't see it.
