How to write an expression which extracts date text from email body

Hi Folks,

 

I am trying to write an expression that will extract, from the email body, the date given after 'Start Date' (in this example, 28th December) and add that date it to the 'Start Time' Field in 'Create event (V2)', and do the same for End Date.

 

Even if I could do that, would the date format be compatible or would I need to add a further expression to convert into an acceptable date format (and if so, what might that look like?)

 

The following leave request has been Approved by your line manager.

 

Employee: xxxx xxxxxxxx

Leave type: ANNUAL LEAVE

Start date: 28-DEC-17

End date: 28-DEC-17

 

Currently the best I can come up with is:

 

substring(body('Html_to_text'),add(lastIndexOf(body('Html_to_text'),'Start date '), 12),9

 

I'm a begginer at this so suspect that I'm some way off.  Any suggestions/help would be greatly appreciated.

 

Many thanks

Pete

Hi

I think there is a missing parenthesis at the end of the expression

 

substring(body('Html_to_text'),add(lastIndexOf(body('Html_to_text'),'Start date'), 12),9)

 

In this link a similar scenario is described, also some date format limitations are detailed

Hope this helps

Hi @pete_whitfield,

 

I agree with @efialttes’s thought almost, I have made a test on my side and please take a try with the following workaround:2.JPG

Within “Start date” action (Compose action), Inputs set to following formula:

substring(body('Html_to_text'),add(indexOf(body('Html_to_text'),'Start date'),12),9)

Within “End date” action (Compose action), Inputs set to following formula:

substring(body('Html_to_text'),add(indexOf(body('Html_to_text'),'End date'),10),9)

 

The flow works successfully as below:3.JPG

 

More details about expressions which could be used in Microsoft Flow, please check the following article:

Best regards,
