从表中获取特定值

Question

I have a script that gets an email address from a .msg file and I have gotten most of the script to work the way I want it.

So for this string:

(Select-String -InputObject $SEMFINAL -Pattern '\w+@\w+\.\w+' -AllMatches).Matches

I get:

Index    : 0
Length   : 15
Value    : email@email.com

How can I filter the results to only get the data for the Value in the table?

Answer 1

This might not be the most graceful solution, but would this work?:

$SEMFINAL = "Hello my address is bob@example.com Thanks. P.S. You can also reach me at robert@example.com" 
(Select-String -InputObject $SEMFINAL -Pattern '\w+@\w+\.\w+' -AllMatches).matches | select value

Output ( Value property of the match objects):

Value
-----
bob@example.com
robert@example.com

To expand the properties to their actual value, change the last portion to

| select -Expand value

to the end.

(Select-String -InputObject $SEMFINAL -Pattern '\w+@\w+\.\w+' -AllMatches).matches | select -Expand value

Output:

bob@example.com
Robert@example.com

I just recently learned about objects and hash tables, which I think is what is going on here. You need to create an object with the values you want assigned to it. Otherwise it will only give you the length of the values.

So something like:

 $EmailInput = (Select-String -InputObject $SEMFINAL -Pattern '\w+@\w+\.\w+' -AllMatches).Matches
 $Email = @{
            "Email" = $EmailInput
        }
        $EmailObject = New-Object -TypeName psobject -Property $Email

I'm still learning, so you may need to mess with it a bit (or a lot), but I think you'll need to put that info into an object if you want to read the actual values instead of just lengths.

If someone else understands objects better please correct me.
