Extract variable length Email Data (Date + ID Number)

[EricC]

Hi Everyone,

I've been following this thread here: https://powerusers.microsoft.com/t5/Building-Flows/Extract-text-from-Body-of-an-email-in-Flow/td-p/5...and I'm able to extract the info I need, the problem is the info I need can change in length. For instance:

I'm using an outlook email trigger > HTML to text > initialize variable

substring(body('Html_to_text'),add(lastIndexOf(body('Html_to_text'),'Date'), 15),11)

This works but it will not work if other data changes in the body of the email since it throws the counts off...

An HTML to text ouput would contain:

Name:

John Smith


ID Number:

666


Office:

Ohio


Date:

8/23/2019

The issue is I really just need the ID Number and Date values, but they change and can be different lengths. 

The ID Number can be 1 digit to 6 digits and the date could be 1/1/2019 (8-10 characters)

Any ideas?

Hi @EricC 

To get the ID from the "HTML to Text" action, you need to create a variable to split the results based on "New Line" character. While creating the "enter" variable, in the value just press enter once, so that this can be used to split the "HTML to Text" response.

Expression Used:

split(body('Html_to_text'),variables('enter'))[7]

Index 7 is used because based on the response shared, after split it was getting returned at the index value 7.

Hope this Helps!

Hi @EricC ,

Please check this similar thread, I have provided an additional method here, please check if it helps you:

https://powerusers.microsoft.com/t5/Building-Flows/Extracting-text-from-email/td-p/334919

It does not need to calculate the length of the message content, by specifying the value to get the data you need.

@v-bacao-msft This works great! Only issue is for the Date since it is the last part of the body of the email there is nothing after it to tell the expression where to stop. How would I go about solving that piece?

Hi @EricC ,

Please try this expression:

trim(last(split(body('Html_to_text'),'Date:')))

Best Regards,
