[BUG] xlsx-renderer: When iterates on empty collection it leaves garbages

[jacekkoziol]

Using template with nested loops, the expected file is generated correctly however few renderer variables (in this case !# END_LOOP item and !# FINISH) are not removed from the generated file.

• template.xlsx
• vm.json.txt
• result.xlsx

(@Siemienik EDIT): Reproduce:

sxr --model vm.json template.xlsx > result.xlsx

@Siemienik I have notice another issue, if the array in the view model data is empty, the variables of the loop section are not removed and they are just placed in the generated file.
I'm attaching the source and result files:

• template.xlsx
• vm-empty-data-array.json.txt
• Result-vm-empty-data-array.xlsx

Yesterday I added a utility which will helps me debug this issue (#134 #151). For now nothing blocks me and I start to fixing this bug ;)

@Siemienik It seems like the issue is caused by empty arrays on which we try perform the loop.
