Assistance with parsing text between characaters

I have a column A that each cell has 3 lines in it.

Example:

Cell A1:
Plugin Output:
Hostname : Dave-L-123456789
Dave-L-123456789 (WMI)

Cell A2:
Plugin Output:
Hostname : Dave-L-222222222
Dave-L-222222222 (WMI)

Cell A3:
Plugin Output:
Hostname : Dave-W-010101010
Dave-W-010101010 (WMI)

These are computer names. Lines 2 and 3 are basically the same thing.
Is there a way to parse this out so it just gives me the computer name? like Dave-W-010101010
There is not set amount of characters for the computer name which make it tough.

The best i've gotten so far is:
=RIGHT(A1,LEN(A1)-FIND(":",A1))
but it just returns both computer names

Thanks

This returns with the computer name from both lines 1 and 2.
=TRIM(
MID(
SUBSTITUTE(A1, " : ", REPT(" ", 99)),
2 * 99 - 98,
99))

I was able to get it working a different way.

=MID(A1,
SEARCH("name",A1+6,
SEARCH(CHAR(10),A1)-1)
