Get numbers between two strings


I’m currently building my first bot and got stuck on this part of the process.

Basically, I need to fetch a series of numbers between two strings.
The strings are always the same, and the numbers are always 6 characters long and always starts with 6. But the amount of number values varies from 1 up to 100

So basically:

And I want the output to be in one row with a space between each number like this:
612345 654321 678901

I want to save this as a variable if possible

I hope you’re able to understand my request.

Use regex function

“(?<=” + “first string” + “)(.*?)(?=” + “last string” + “)”

You can use Regex pattern \d+ in Match activity and loop trough Regex Result to form the string

Your script works like a charm!

However, the full document that i need to get the numbers from contains additional numbers and fields that I dont want to be included.

Therefore I need it to specifically extract the data between “start” and “end” and nothing else.

And also, the number values are unique per document so I need it to fetch the string from the document and not have it pre-determined

I modified your script and now it works.
However when I tick the “ignore white space” checkbox it causes an error in the message box:

The output looks like:

But I want it to look like:

But when I check “ignore white space” it fails to run

@Hgren Replace Newline with space as follows

 Assign str = str.Replace(Environment.newline," ")

How do you mean?

@Hgren its working

Still have the same problem.

I got it to fetch the numbers after assigning the text from the document to a variable with Read Text File.

But it still outputs them like this:

And not like this:
612345 654321 678901

@Hgren Check this xaml

Yes I tried using this.
But in your example you have the text predefined in a variable,
Str = “start 612345 654321 678901”

But since this bot is going to repeat this process for multiple text documents I need it to use Read Text Document to define the variable.

@Hgren Can you attach sample text file or sample data

This is how the file looks:
OID: 12345 test
DID: 34214 test

Error message:
20190926 22:36:30 [0000000] (ERROR)
Split: 7

Affected messageIDs:
678901 nill
Product:: nill

I need to extract the numbers between “Affected messageIDS:” and “Account.Nr”.
This I’ve solved.

I simply need the message Ids to be in a single row divided by a space and not on top of each other, like this: 612345 654321 678901

@Hgren Check this and let me know
