Parse email body paragragh in Powershell - regex

Question

I am creating a script to parse outlook email body, so that I can get say an (ID number, date, name) after strings ID: xxxxxx Date: xxxxxx Name:xxxxx. I was looking around and could not fine anything that allows me to take the string after a match.
What I manage so far is to query for the email that was send by the specific users from outlook.
Add-Type -Assembly "Microsoft.Office.Interop.Outlook"
$Outlook = New-Object -ComObject Outlook.Application
$namespace = $Outlook.GetNameSpace("MAPI")
$inbox = $namespace.GetDefaultFolder([Microsoft.Office.Interop.Outlook.OlDefaultFolders]::olFolderInbox)
foreach ($items in $inbox.items){if (($items.to -like "*email*") -or ($items.cc -like "*email.add*")){$FindID = $items.body}}
Now that I have the email body in the for loop I am wondering how I can parse the content?
In between the paragraphs will be a text something like this
ID: xxxxxxxx
Name: xxxxxxxxx
Date Of Birth : xxxxxxxx
I did some testing on the below to see if I can add that into the for loop but it seem like I cannot break the paragraphs.
$FindID| ForEach-Object {if (($_ -match 'ID:') -and ($_ -match ' ')){$testID = ($_ -split 'ID: ')[1]}}
I get the following results which I cannot get just the ID.
Sample Result when i do $testID
xxxxxxxx
Name: xxxxxxxxx
Date Of Birth : xxxxxxxx
Regards,
xxxxx xxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxx
How do I get just the results I want? I am just struggling at that portion.

You'll need a Regular Expression with (named) capture groups to grep the values. See example on rexgex101.com.
Provdid $item.bodyis not html and a single string, this could work:
## Q:\Test\2018\07\24\SO_51492907.ps1
Add-Type -Assembly "Microsoft.Office.Interop.Outlook"
$Outlook = New-Object -ComObject Outlook.Application
$namespace = $Outlook.GetNameSpace("MAPI")
$inbox = $namespace.GetDefaultFolder(
[Microsoft.Office.Interop.Outlook.OlDefaultFolders]::olFolderInbox)
## see $RE on https://regex101.com/r/1B2rD1/1
$RE = [RegEx]'(?sm)ID:\s+(?<ID>.*?)$.*?Name:\s+(?<Name>.*?)$.*?Date Of Birth\s*:\s*(?<DOB>.*?)$.*'
$Data = ForEach ($item in $inbox.items){
if (($item.to -like "*email*") -or
($item.cc -like "*email.add*")){
if (($item.body -match $RE )){
[PSCustomObject]#{
ID = $Matches.ID
Name = $Matches.Name
DOB = $Matches.DOB
}
}
}
}
$Data
$Data | Export-CSv '.\data.csv' -NoTypeInformation
Sample output with above anonimized mail
> Q:\Test\2018\07\24\SO_51492907.ps1
ID Name DOB
-- ---- ---
xxxxxx... xxxxxxx... xxxxxx...

I don't have Outlook available at the moment, but i think this will work
Add-Type -Assembly "Microsoft.Office.Interop.Outlook"
$Outlook = New-Object -ComObject Outlook.Application
$namespace = $Outlook.GetNameSpace("MAPI")
$inbox = $namespace.GetDefaultFolder([Microsoft.Office.Interop.Outlook.OlDefaultFolders]::olFolderInbox)
$inbox.items | Where-Object { $_.To -like "*email*" -or $_.CC -like "*email.add*"} {
$body = $_.body
if ($body -match '(?s)ID\s*:\s*(?<id>.+)Name\s*:\s*(?<name>.+)Date Of Birth\s*:\s*(?<dob>\w+)') {
New-Object -TypeName PSObject -Property #{
'Subject' = $_.Subject
'Date Received' = ([datetime]$_.ReceivedTime).ToString()
'ID' = $matches['id']
'Name' = $matches['name']
'Date of Birth' = $matches['dob']
}
}
}
