Parsing the message field in security event.code 4624

The information that I want is located under the first sub-header "Subject" and "Network Information". My basic question is this, how do I pull this information out of the Message field and display it along with the Time and event ID. From what I can gather the Message field is actually an array of strings so I should be able to pull it by element but I cannot figure out how to do this.

Anyone please?,

This event is generated when a logon session is created. It is generated on the computer that was accessed.

The subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe.

The logon type field indicates the kind of logon that occurred. The most common types are 2 (interactive) and 3 (network).

The New Logon fields indicate the account for whom the new logon was created, i.e. the account that was logged on.

The network fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.

The impersonation level field indicates the extent to which a process in the logon session can impersonate.

The authentication information fields provide detailed information about this specific logon request.
	- Logon GUID is a unique identifier that can be used to correlate this event with a KDC event.
	- Transited services indicate which intermediate services have participated in this logon request.
	- Package name indicates which sub-protocol was used among the NTLM protocols.
	- Key length indicates the length of the generated session key. This will be 0 if no session key was requested.

This post is related to parsing these messages, but it's not the approach I would recommend. This post may be a better way of doing it.
