Replace a string

Hi everyone, 

 

I have a string variable with the values "36.43.40.42.38.419.37.45." and I want to replace the last value ".45." the last value is always between dots.

 

How can I do that

There's no need to overthink this logic.

 

Here you go with simple one:

Code:

SET Decimal TO $'''36.43.40.42.38.419.37.45.'''
Variables.CreateNewList List=> DecimalList
Variables.AddItemToList Item: $'''36.43.40.42.38.419.37.45.''' List: DecimalList

Variables.AddItemToList Item: $'''78.56.34.12.90.234.56.78.''' List: DecimalList
LOOP FOREACH CurrentItem IN DecimalList
    Text.Replace Text: CurrentItem TextToFind: $'''\\.(\\d+)\\.(?=[^.]*$)''' IsRegEx: True IgnoreCase: True ReplaceWith: $'''%''%''' ActivateEscapeSequences: True Result=> Replaced

Hi @Diego_Marquez !

 

You can try using scripting languages like Python or Powershell as it a lot faster.

Here is one flow:

NathanAlvares24_0-1719437552543.png

 

You can choose either Powershell or Python as both give the same result.

Powershell code:

 

 

 

# Original string
$originalString = "%String%"

# Split the string by the dot
$splitArray = $originalString -split "\."

# Remove the last empty element if it exists
if ($splitArray[-1] -eq "") {
    $splitArray = $splitArray[0..($splitArray.Length - 2)]
}

# Remove the last value
$splitArray = $splitArray[0..($splitArray.Length - 2)]

# Get the second last value and append the new value
$newValue = "NEWVALUE"
$splitArray[-1] = $splitArray[-1] + $newValue

# Join the array back into a string
$newString = $splitArray -join "."

# Output the new string
$newString

 

 

 

 

Python code:

 

 

 

# Original string
original_string = "%String%"

# Split the string by the dot
split_list = original_string.split(".")

# Remove the last empty element if it exists
if split_list[-1] == "":
    split_list = split_list[:-1]

# Remove the last value
split_list = split_list[:-1]

# Get the second last value and append the new value
new_value = "NEWVALUE"
split_list[-1] = split_list[-1] + new_value

# Join the list back into a string
new_string = ".".join(split_list)

# Output the new string
print(new_string)

 

 

 

 

Full code of the flow (just copy and paste into your flow):

 

 

 

SET String TO $'''36.43.40.42.38.419.37.45.'''
@@copilotGeneratedAction: 'False'
Scripting.RunPowershellScript.RunPowershellScript Script: $'''# Original string

# Remove the last empty element if it exists
if ($splitArray[-1] -eq \"\") {
    $splitArray = $splitArray[0..($splitArray.Length - 2)]
}

# Remove the last value
$splitArray = $splitArray[0..($splitArray.Length - 2)]

# Get the second last value and append the new value
$newValue = \"NEWVALUE\"
$splitArray[-1] = $splitArray[-1] + $newValue

# Join the array back into a string
$newString = $splitArray -join \".\"

# Output the new string
$newString''' ScriptOutput=> PowershellOutput ScriptError=> ScriptError

# Remove the last empty element if it exists
if split_list[-1] == \"\":
    split_list = split_list[:-1]

# Remove the last value
split_list = split_list[:-1]

# Get the second last value and append the new value
new_value = \"NEWVALUE\"
split_list[-1] = split_list[-1] + new_value

# Join the list back into a string
new_string = \".\".join(split_list)

# Output the new string
print(new_string)''' PythonVersion: System.PythonVersion.Python3 ScriptOutput=> PythonScriptOutput ScriptError=> ScriptError

 

 

 

 

Output:

Before:

After:

NathanAlvares24_2-1719437753968.png

 

NathanAlvares24_3-1719437784189.png

 

So it will replace ".45." which comes in format as you said some data between the dots and at the end always with any value you specify in the script. I replaced that with "NEWVALUE"

 

Other input:

After:

I hope this helps.
