Powershell: Splitting String into CSV - string

Question

I have a (hopefully) quick question that I can't seem to work out on my own.
I have a string:
ITEM1 Quantity: 12x 355ml bottlePrice: $23.95 $23.50 SAVE $0.45
That I would like to split out and insert into a CSV file. The columns in the generated CSV, and their values, would be:
Name: (everything before "Quantity:" in the above string.)
Quantity: (between Quantity and x)
Size: (Everything between x and bottle)
OrigPrice: (Everything after Price and the second $ sign)
SalePrice: (Everything between OrigPrice and SAVE)
Savings: (Everything after "SAVE")
I hope this all makes sense, I can provide more info if needed.
I appreciate the help!

Answer 1

How about something like:
$subject = 'ITEM1 Quantity: 12x 355ml bottlePrice: $23.95 $23.50 SAVE $0.45'
if ($subject -cmatch '^(?<Name>.*)Quantity:(?<Quantity>.*)x(?<Size>.*)bottle\s*Price:(?<OrigPrice>.*)\s*(?<SalePrice>\$.*)SAVE(?<Savings>.*)$') {
$result = $matches[0]
} else {
$result = ''
}
"Matches:"
$matches
I couldn't tell if there really needed to be a space between bottle & Price (it didn't look like it, but it'll handle it if there is).
If you need the name, you can access it like:
$matches["Name"]
A better solution (and one that actually gets it to CSV format, would be something like the following (thanks to #nickptrvc for pointing out what I missed):
function Read-Data {
[cmdletbinding()]
param(
[parameter(Mandatory)][string]$Path
)
$reader = [System.IO.File]::OpenText($Path)
while(( $subject = $reader.ReadLine()) -ne $null ) {
if ($subject -cmatch '^(?<Name>.*)Quantity:(?<Quantity>.*)x(?<Size>.*)bottle\s*Price:(?<OrigPrice>.*)\s*(?<SalePrice>\$.*)SAVE(?<Savings>.*)$') {
$result = $matches[0]
$obj = [PSCustomObject]#{
Name=$matches["Name"].trim();
Quantity=$matches["Quantity"].trim();
Size=$matches["Size"].trim();
OrigPrice=$matches["OrigPrice"].Trim();
SalePrice=$matches["SalePrice"].Trim();
Savings=$matches["Savings"].Trim()
}
$obj
}
}
}
Then, to use it, save this to a file (I called mine Read-Data.ps1), source the file, and then you have two options: 1) you can use ConvertTo-Csv to simply convert the objects to CSV, and return the result to the screen, or you can use Export-Csv to save it to a file:
. C:\Test\Convert-Data.ps1
Read-Data -Path C:\Test\datafile.dat | ConvertTo-Csv -NoTypeInformation
or
Read-Data -Path C:\Test\datafile.dat | Export-Csv -NoTypeInformation -Path C:\Test\datafile.csv
