Regex to retrieve value from table

We have users replying on an e-mail and we need to retrieve the date mentioned in the table.

For the moment I made the following code to do that for us:

$temp = ($Mail.Body.Text -creplace '(?m)^\s*\r?\n' -split "User name`r`n`tLogon name`r`n`tEnd date`r`n`tNew end date")[1]
(($temp -split "`r`n`t")[3] -split "`r`n")[0]

As you can see, it's quite long and very much relying on
. Is there an easier way to retrieve the date? With
or a
or something?

The table format in the e-mail is always the same, as the users needs to fill in the date in the HTML table. So we need to be able to read that table. In the example below the result would be

Example of such an e-mail:

Date added below

ded after its end date. More text...

You could use Select-String to find date-like patterns and select the last one:

$EndDate = ($Mail.Body.Text |Select-String '\d{2}/\d{2}/\d{4}' -AllMatches).Matches[-1].Value
