Hi Keith
here's a quick answer typed into email (i.e. not tested at all, sorry)
function displayArray @pArray
# create variables that point to the line and column of the array
local tLineItem, tColumnItem
# create a variable that stores the output for printing
local tPrintLine
put empty into tPrintLine
# loop through each row of the array
put item 2 of line 1 of the extents of pArray into tNumItem
repeat with I = 1 to tNumItems
# loop through each column of the array
repeat for each key K in pArray[0] -- loop through the tags
put [pArray[0][K] into tTag
# write content of the array to tPrintLine
put pArray[I] & "," after tPrintLine
end repeat
# insert a return after each row we have written to tPrintLine
put return after tPrintLine
end repeat
return tPrintLine
end displayArray

Hi folks,
I’m using LiveCode to parse a set of xml files with varying subsets of tags
(dmarc reports) into a CSV file.
The utility iterates through the files in the folder and the lines of the
files, to identify unique opening tags and their content, all of which get
parsed into an array:
- Tags go into aDetails[0][tTagName]
- Values go into aDetails[tFileNumber][tTagName]
This is then displayed as a table, using the function below, borrowed from an LC
lesson

local tLineItem, tColumnItem
# create a variable that stores the output for printing
local tPrintLine
put empty into tPrintLine
# loop through each row of the array
repeat for each element tLineItem in pArray
# loop through each column of the array
repeat for each element tColumnItem in tLineItem
# write content of the array to tPrintLine
put tColumnItem & "," after tPrintLine
end repeat
# insert a return after each row we have written to tPrintLine
put return after tPrintLine
end repeat
return tPrintLine
end displayArray
However, the above function seems to assume that all array elements have
content, so I’m getting problems where there are empty elements in the xml
files coming from various sources.
I’m sure the loop repeating for each element can be refined to check for ‘empty
cells’ by the tTagName key in my array but my LC array knowledge is to sparse
to begin the search.
Dos anyone have any tips on where I should start looking?
Thanks & regards,
Keith
