Parse log file using powershell

Question

Hi,
Am pretty new to Powershell and would require anyone of your assistance in setting up a script which parse thru a log file and provide me output for my requirements below.
I would like to parse the Main log file for Barra Aegis application(shown below) using powershell.
Main log = C:\BARRALIN\barralin.log
Model specific log = C:\BARRALIN\log\WG*.log
Requirements :
1. scroll to the bottom of the log file and look for name called "GL Daily" and see the latest date which in the example log below is "20150203"
note : Name "GL Daily" and date keep changing in log file
2. Once entry is found i would like to have a check to see all 3 entries PREPROCESS, TRANSFER, POSTPROCESS are sucess.
3. If all 3 are success i would like to the script to identify the respective Model specific log number and print it out.
E.g if you see the sample log below for "GL Daily", it is preceded by number "1718" hence script should append the model log path with "WG00" along with 1718, finally it should look something like this  C:\BARRALIN\log\WG001718.log.
4. If all 3 items or anyone of them are in "failed" state then print the same log file info with WG001718.log
Any help on this would be much appreciated.
Thank You.

Hi All,
I was writing a function in power shell to send email and i was looking to attach lines as and when required to the body of the email. but am not able to get this done..Here's my code
Function Email ()
$MailMessage = New-Object System.Net.Mail.MailMessage
$SMTPClient = New-Object System.Net.Mail.SmtpClient -ArgumentList "mailhost.xxx.com"
$Recipient = "[email protected]"
If ($MessageBody -ne $null)
$MessageBody = "The details of Barra $strsessionProduct model is listed below
`rHostName : $localhost
`r Model Run Date : $Date
`r Model Data Date : $DateList1
`r`n Click for full job log"+ "\\"+$localhost+"\E$\Local\Scripts\Logs "
$MailMessage.Body = $MessageBody
If ($Subject -ne $null) {
$MailMessage.Subject = $Subject
$Sender = "[email protected]"
$MailMessage.Sender = $Sender
$MailMessage.From = $Sender
$MailMessage.to.Add($Recipient)
If ($AttachmentFile -ne $null) { $MailMessage.Attachments.add($AttachmentFile)}
$SMTPClient.Send($MailMessage)
$Subject = "Hello"
$AttachmentFile = ".\barralin.log"
$MessageBody = "Add this line to Body of email along with existing"
Email -Recipient "" -Subject $Subject -MessageBody $MessageBody -AttachmentFile $AttachmentFile
as you can see before calling Email function i did add some lines to $MessageBody and was expecting that it would print the lines for $MessageBody in Email Function along with the new line. But thats not the case.
I have tried to make $MessageBody as an Array and then add contents to array
$MessageBody += "Add this line to Body of email along with existing"
$MessageBody = $MessageBody | out-string
Even this didnt work for me. Please suggest me any other means to get this done.
THank You
