Map Array with Select() Action

(0) ShareShare
ReportReport
Posted on by wshalex123 160

Hi all,

 

iam generating an Array, which is sent to PowerApps later, out of a Text File.

My Text file looks like this:

wshalex123_0-1698647632776.png

In an ApplyToAll loop iam removing all unrelevant lines/rows.
So the first output of the FilterArray Action looks like this: 

[
  "DXFSHEA3_1",
  "2157",
  "496.33",
  "0",
  "OFF",
  "1088.5",
  "258.165",
  "0",
  "10",
  "10",
  "0"
]
 
Now i want to sum all filtered rows into a variable, map them and send it back to PowerApps. This is where i don't now how to continue and nearly all tutorials on the web aren't working. I daresay that the input data is a mess yeah. 
 
This is my solution for now, but i know it's wrong and you can see it in the Select (Here: "Auswählen") Action:
wshalex123_1-1698648740255.png

 

Problem is iam getting mutiple results after the Select() Action, where only should be one!

 

[
  {
    "Artikel": "DXFSHEA3_1",
    "Länge": "2157",
    "Breite": "496.33",
    "X": "1088.5",
    "Y": "258.165"
  },
  {
    "Artikel": "DXFSHEA3_1",
    "Länge": "2157",
    "Breite": "496.33",
    "X": "1088.5",
    "Y": "258.165"
  },
 .... 
 
Thats probably because i should do the Select Action after the ApplyToAll? But if i do that, i got problems adding the output of filter array to the array variable...
 
Can anybody help me with a solution for this? 
 
Thanks in advance.
 
Cheers,
Alex

    Just a few questions:

    1. Is your text file a tab delimited file?
    2. Is it possible to upload a copy of the file so we could work with it directly?
    3. What exactly are you trying to sum? Are you looking to add up all the lengths across all rows, all the angles across all the rows, etc.? Or is it grouped by Part Name - so sum of lengths across each of the Part Names?

    Hi @grantjenkins,

     

    of course, i'll attach the file in this message. Open it with Notepad or edit.

    No it's delimited mit spaces. It's trash to work with, but i already made it work to remove all unrelevant rows and data. 

     

    Sum is the wrong word probably. All i want is the data of this file in an array format, to put it into a collection in PowerApps later on. The Lengths, Angles etc should not be summed. It should look something like this:

     

    {
            "Artikel": "DXFSHEA3_1",
            "Länge": "2157",
            "Breite": "496.33",
            "X": "1088.5",
            "Y": "258.165"
          },
          {
            "Artikel": "DXFSHEA3_1",
            "Länge": "2157",
            "Breite": "496.33",
            "X": "1088.5",
            "Y": "764.465"
          },
          {
            "Artikel": "DXFSHEA2_1",
            "Länge": "2057",
            "Breite": "437.67",
            "X": "1038.5,
            "Y": "1241.435"
          }

    ... and so on. So i can work with this data and process it.

    Data

    Compose with the file content

     

    DataStringArray

    Compose that splits the lines and removes spaces

     

     

    split(
	replace(
		replace(
			replace(
				replace(
					outputs('Data'),
					' ',
					' '
				),
				' ',
				' '
			),
			' ',
			' '
		),
		' ',
		' '
	),
	decodeUriComponent('%0A')
)

     

     

     

    DataStringArrayFilteredForEmpty

    Filter that removes empty lines

    From: @outputs('DataStringArray')

    Filter: @not(equals(item(), string(null)))

    This looks better 😉: @not(empty(item()))

     

    DataObjectArray

    Select that creates the objects

    From (Skip the headlines)

     

     

    skip(body('DataStringArrayFilteredForEmpty'), 5)

     

     

     article

     

     

    split(item(), ' ')[0]

     

     

    length

     

     

    split(item(), ' ')[1]

     

     

    width

     

     

    split(item(), ' ')[2]

     

     

     

    etc.

     

    NewData

    Compose that removes duplicates

     

     

    union(body('DataObjectArray'), json('[]'))

     

     

     

    Create HTML table

    Just to check the result

     

     

    sort(outputs('NewData'), 'article')

     

     

     

    The output:

    article length width x y
    DXFPAR0104_1 64.755 64.755 0 OFF
    DXFPAR0117_1 660 215 90 OFF
    DXFPAR0119_1 162 80 0 OFF
    DXFPAR0121_1 84.26 176.507 270 OFF
    DXFPART4_1 1200 650.002 270 OFF
    DXFPUNC0_1 293 162 180 OFF
    DXFPUNC5_1 670 257.07 0 OFF
    DXFSHEA2_1 2057 437.67 0 OFF
    DXFSHEA3_1 2157 496.33 0 OFF
    DXFSHEA4_1 636 281 90 OFF
    DXFSHEA7_1 100 50 90 OFF
    DXFSHEA7_1 100 50 0 OFF

     

    Note that there are two rows with article DXFSHEA7_1 because the y values are different.

    To get only one row per article you need to define which row to use and depending on this the object creation may be different.

    Hopefully this is what you're after. I was trying to do it without using a loop, but no luck there.

     

    See full flow below. I'll go into each of the actions.

    grantjenkins_0-1698660353562.png

     

    Get file content using path retrieves the file.

    grantjenkins_1-1698660381170.png

     

    Compose converts the file content to text using the following expression.

    base64ToString(outputs('Get_file_content_using_path')?['body']?['$content'])

    grantjenkins_2-1698660432145.png

     

    Filter array Rows splits each row by carriage return and new line, then skips the first 5 rows (headers), and removes any empty rows (seems there are a few empty rows at the end of the file).

    //From
skip(split(outputs('Compose'), decodeUriComponent('%0D%0A')), 5)

//Condition
item()

    grantjenkins_3-1698660571731.png

     

    Select uses the output from Filter array Rows and splits by space.

    //Map
split(item(), ' ')

    grantjenkins_4-1698660636341.png

     

    Initialize variable creates a variable called data of type Array and sets it as an empty array.

    grantjenkins_5-1698660682091.png

     

    Apply to each uses the output from Select so it iterates over each of the rows of data.

    grantjenkins_6-1698660716855.png

     

    Filter array uses the Current item (current row we are iterating over) and removes any empty items.

    //Condition
item()

    grantjenkins_7-1698660802257.png

     

    Append to array variable appends the fields for each item to the data variable.

    {
"Artikel": @{body('Filter_array')?[0]},
"Länge": @{body('Filter_array')?[1]},
"Breite": @{body('Filter_array')?[2]},
"X": @{body('Filter_array')?[5]},
"Y": @{body('Filter_array')?[6]}
}

    grantjenkins_8-1698661188868.png

     

    If we ran the flow now, the data array variable would contain an array of all the objects.

     

    After the Apply to each, I've added a Compose called Output that shows the value of our data array.

    grantjenkins_9-1698661272409.png

     

    A sample of the output is below (I've just shown the first 6 rows).

    To avoid the loop, just remove the unnecessary spaces in advance.

    @Chriddle i tried your solution but didn't get along with one error at the DataObjectArray (Select) Action.

    I think It's because the last two "\r" you got this error too? You know how i also can skip the last two rows?

    Here's another more streamlined solution based on @Chriddle using replace to remove the spaces.

     

    grantjenkins_0-1698675103197.png

     

    Get file content using path is the same as before.

    grantjenkins_1-1698675130008.png

     

    Filter array uses the following expression.

    //From
skip(
 split(
 replace(
 replace(
 replace(
 replace(
 base64ToString(outputs('Get_file_content_using_path')?['body']?['$content']),
 ' ',
 ' '
 ),
 ' ',
 ' '
 ),
 ' ',
 ' '
 ),
 ' ',
 ' '
 ), 
 decodeUriComponent('%0D%0A')
 ),
 5
)

//Condition
item()

    grantjenkins_2-1698675273854.png

     

    Select uses the output from Filter array and the following mappings.

    //Artikel
split(item(), ' ')[0]

//Länge
split(item(), ' ')[1]

//Breite
split(item(), ' ')[2]

//X
split(item(), ' ')[5]

//Y
split(item(), ' ')[6]

    This is handled by the Filter (DataStringArrayFilteredForEmpty) in my flow.

    In DataStringArray replace decodeUriComponent('%0A') with decodeUriComponent('%0D%0A')

     

    Which one you need to use depends on whether your text file uses Unix-style or Windows-style line breaks.

    How do you handle null values in the select when you manually put a item number in here? 

    for example when item()[0] (Artikel)  is null it will then point the [0] to item Länge etc.
