In input raw data:

  1. There is no leading and trailing white space in each row.
  2. There is no white space among rows. The white space shown is intended to make it look presentable/understandable. White space in final output is not needed either.
  3. Symbol ">" is missing in few rows. This is not a typo.

Can you give me direction on how to reformat using bash/shell script (sed, awk etc). I'm lost.

Using awk:

awk '{
  if (sub(/\.xml /, ".xml,")){      # replace `.xml ` with `.xml,`
    if (NR>1 && is_processed != 1){ # xml line was not printed?
       print xml","                 # print previous xml line + `,`
    }
    sub(/>?[0-9]+\.ABC$/, ",") # replace strings `>1446815.ABC` or `1244115.ABC` with `,`
    xml=$0                     # save line in variable `xml`
    is_processed=0             # clear flag
  }
  else {
    if (!NF) next  # skip empty line
    sub(/ /, ",")  # replace 1st ` ` with `,`
    sub(/ /, ",")  # replace 2nd ` ` with `,`
    print xml$0    # print xml line + current line
    is_processed=1 # set flag
  }
}
END {
  # print possible remaining line
  if (is_processed != 1) print xml","
}' filein > fileout

The if-block processes the line containing .xml and saves it in variable xml. The else-block processes the following "children" of the xml line and prints the xml line plus the modified line with the first two space characters replaced by a comma. Empty lines are skipped.

If there are no "children", then the xml line with an additional comma is printed in the top if-block (if the line number is greater 1) or in the END-block.

Output (fileout):

0bef-82-46-8a-9a0b.xml,"Fruits/Mango Apple /Plum cherry date",0bef-82-46-8a-9a0b,5da-0-ba-c1-1a9,"Fruits/Pear Banana/Plum orange mango"

Using Miller (https://github.com/johnkerl/miller) and sed

<input.csv sed -r 's|^(.+")(.?[0-9]+.+)$|\1 "\2"|g' | \
mlr --csv -N --ifs " " put 'if($1=~"xml") {$4=$1;$5=$2}' \
then unsparsify \
then fill-down -f 4,5  \
then count-similar -g 4 \
then filter '($1=~"xml" && $count==1) || ($1!=~"xml" && $count>1)' \
then reorder -f 4,5,1,2,3 \
then put 'if($2=~"Fru"){$1="";$2="";$3=""}' \
then cut -x -f count

you will have
