How to split a text using 'delmiter _'

Posted on by kunal_jain28598 28
Hi,
I have an expression from which I need to extract a specific value using the delimiter '_'.
The extracted text is:-
"Split_1.pdf"
And the text we need to extract from it is only '1'.
How would anyone be able to do it?

    Use split() Function:
    First, split the text by the _ delimiter, which will give you an array with two elements: "Split" and "1.pdf".
    Use another split() to remove .pdf
    Then split the second part "1.pdf" using the . delimiter to extract the value 1.
     
    split(split('Split_1.pdf', '_')[1], '.')[0]

    Better way might be to use Parse text -action to just get the number without needing to split it into a list. So you get the number with just one action when using regex that finds the number between underscore and .pdf

    Text to find (regex): (?<=_)\d+(?=\.pdf)
    Is regular expression     Toggled on


    Then Match variable has the number inside it:


    ​​​​​​​
    If you want to do this with split action:
    Change "Delimeter type" to be "Custom" and then add to "Custom delimeter field "_" like so:
     
    Then you get [Split, 1.pdf]
     
    Then you could use replace on the second item on the list which s %TextList[1]% and text to find .pdf and replace with %''% (empty string)
     
    Result is 1
