Answer by RomanPerekhrest for Identify empty xml files?

to identify and write all xml file names which are empty to a text file for reporting purpose

find + xmlstarlet solution:

find . -type f -name "*.xml" -exec bash -c \
'v=$(xmlstarlet sel -t -i "count(//*)=1 and //*[1][not(normalize-space())]" -o 1 -b $1);
[[ -n "$v" ]] && echo "$1" >> "empty_xml.txt"' _ {} \;

empty_xml.txt file should contain a list of needed filenames/filepaths
