I need some help trying to parse a .txt file and capturing certain fields to be able to dump that information into a SQL table for analysis and reporting.
This is what the .txt looks like and I have defined the fields I want captured, so basically each time it finds this line dump out everything to the right of the field catcher.
/* ----------------- ????????? ----------------- */
2. Then it would try to find these tags: Notice on the first lookup insert_job: and job_type: are on the same line. All other field catchers are on a single line.
Capture tags in BOLD:
insert_job: XXXXXXXXX job_type: XXX
command: XXXXXXX
days_of_week: xx,xx,xx
start_times: "xx:xx"
run_calendar:
start_mins:
machine:
watch_file:
box_name:
3. When it finds any of these tags take everything right of the colon(:) load to variable then insert those values to SQL table.
4. The lookup ends when it finds and blank line during lookup(extraction,) or the next:
/* ----------------- ????????? ----------------- */
5. I tried to show how records are parsed using 1st record -- 2nd record
6. Not all records will contain the fields to capture, so those values can be filled with null value
7. SQL table and field mapping to text file:
SQL Lookup
jobname -- Insert_Job
job_type -- job_type
dayofweek -- days_of_week
starttime -- start_times
runcalendar -- run_calendar
startmins -- statr_mins
machine -- machine
watchfile -- watch_file
boxname -- box_name
Many thanks for any help you can provide.
/* ----------------- 1st record ----------------- */

/* ----------------- 2nd record ----------------- */

Some real or better-simulated data for the file is absolutely necessary for us to help you here or the answer will be either to create a BCP format file or import the whole row and do a computational "Hail Mary".

Well this should get you an array with all the records in it in a PSObject format, from there you would need to go through it build your insert statements.
$output = @()
$currentCapture = $null
$startCapture = $null
$content = (Get-Content "C:\Temp\testy.txt")
$content = $content -replace 'job_type:', "rnjob_type:"
ForEach($line in ($content -split "rn"))
{
If($line -match '/\* -----------------.*----------------- \*/')
{
$startCapture = $true
if($currentCapture -ne $null)
{
$output += (New-Object PSObject -property $currentCapture)
}
$currentCapture = $null
}
ElseIf($line.Trim().length -eq 0 -and $startCapture -eq $true -and $currentCapture -ne $null)
{
$startCapture = $false
}
ElseIf($line.Trim().length -gt 0 -and $startCapture -eq $true)
{
If($currentCapture -eq $null)
{
$currentCapture = @{}
}
$index = $line.IndexOf(":")
$key = $line.Substring(0, $index)
$value = $line.Substring($index + 1, $line.Length - ($index + 1))
$currentCapture.Add($key.ToString(), $value.ToString())
}
}
if($currentCapture -ne $null)
{
$output += (New-Object PSObject -property $currentCapture)
}
ForEach($record in $output)
{
$record | Format-Table *
}

cool thanks... I'll give it a test against my file..

Ok... no actual data. Moving on. Good luck. 😉

Sorry Jeff, --- Thanks ZZartin for sample... I did include error messages from run
To you both sorry for not including a sample file to work from.. This sample has some of the tags in my example and others missing which is a good example because to all sections will contain ALL tags.

ZZartin, after I created my sample file that I attached, and ran your sample script against it worked, and dumped the tags out like expected.
The file contains CRLF for each line in the file.. would that be the issue?
Thanks again..

Can't seem to get original file to process gets errors listed above.. sample file will process.
Any thoughts or suggestions?
Thanks again

Instead of making us go back an unknown number of posts to find them, why not just post them again. You're looking right at them. 😉

How could original script posted by zzartin, be modified to just pickup these tags during extraction? Currently it's finding ALL which do some testing with the file might be the issue.
Thanks.
Insert_Job
job_type
days_of_week
start_times
run_calendar
start_mins
machine
watch_file
box_name

When you're pulling the records out of the array to do the inserts you should be able to just pull the fields you need.
May 2, 2022 at 11:30 pm
Sorry maybe what I'm asking is if your original script could only find tags listed rather than reading entire record set.
When I did some samples it maybe running into an issue getting things other than these:
Insert_Job
job_type
days_of_week
start_times
run_calendar
start_mins
machine
watch_file
box_name
