Removing blank lines

I have some plain text that looks like this:

 

MONDAY, MAY 20
 
 
VICTORIA DAY
 
ALL OFFICES CLOSED
 
 
 
WEDNESDAY, MAY 22
 
 
NORMAL SCHEDULE
 
 
When I try to remove the blank line 
replace(body('Html_to_text'),variables('txtCR'),'')  //txtCR is just a variable with a line break
 
I get this:
 
MONDAY, MAY 20VICTORIA DAYALL OFFICES CLOSEDWEDNESDAY, MAY 22NORMAL SCHEDULE
 
Any suggestions to get an output like this (where there are line breaks after lines with text)?:
MONDAY, MAY 20
VICTORIA DAY
ALL OFFICES CLOSED
WEDNESDAY, MAY 22
NORMAL SCHEDULE

Hi @ContentGroup ,

 

Please try the following methods to achieve your needs.

 

  • Initialize String variable-Breakline, and add a carriage return inside Value.
  • Initialize another String variable to store the expected result.
  • Use the variable Breakline to split the Plain text, generate an array, and use Apply to each to iterate over the array.
  • Use Condition to determine whether the currently traversed element is empty. If it is not empty, append the current element to the Text variable. Note that you also need to add a carriage return in Value.

You would probably want to convert the text to HTML using the Content Conversion connector (docsso it is easier to figure out which characters are still hanging around in the blank spaces. They discuss it in this thread

This does work and I willl accept this as the answer.  The only issue is the respond time is longer than what I would want, the for each loop took about 12 seconds, for my use case this flow is initialized by a http request and ends with a response to that request, so the user's browser is waiting for 12 seconds for the information to come back.

Your solution gave me an idea to speed things up, I create two variables, one with 1 carriage return and one with 2 carriage returns.  then i created an output variable which contained the text, did a do until loop with the criteria of until the output variable does not contain the 2 carriage returns, in the loop i just replace 2 carriage returns with 1 carriage return and this saved about 9 secs:

Thanks for your help

Small suggestion! 

After the split item the  condition you have added double quotes with space where as most of the scenarios the rows are empty. If you find rows that are empty just use double quotes without space that should work!

 

Well presented your solution, thanks
