Question

Using PowerShell, we are able to successfully extract lines we need from doc.
Code:
Get-Content "C:\Contract.doc" |
Select-String -Pattern "in relation to any Facility" |
Select -Property #{Name = 'Name'; Expression = {$_.Line}}
Output:
Name
----
in relation to any Facility A Loan [2% ] per cent. per annum;
in relation to any Facility B Loan [ 5% ] per cent. per annum;
What we are looking for is extract 2% ... 5% from the above output
Code, we are trying is not working for us:
Get-Content "C:\Contract.doc" |
Select-String -Pattern "in relation to any Facility" |
Select -Property #{Name = 'Name'; Expression = {$_.Line}} |
Select-String '\[\?+([^?]+)\?+\]' |
ForEach-Object { $_.Matches.Groups[1].Value }
Can anyone please help how to extract like below:
"in relation to any Facility A Loan [2% ] per cent. per annum", "2%"
Part of Word Doc: Contract doc
"Margin" means:
(a) in relation to any Facility A Loan [2% ] per cent. per annum;
(b) in relation to any Facility B Loan [ 5% ] per cent. per annum;
(c) [in relation to any Incremental Facility Loan, the percentage rate per annum specified as such in the Incremental Facility Notice relating to the Incremental Facility under which that Incremental Facility Loan is made or is to be made;]

Answer 1

Check on the next snippet.
Get-Content C:\Contract.doc |
Select-String -Pattern #'
\b(in relation to any Facility [A-Z] Loan \[\s*(\d+%)\s*\] per cent. per annum);
'# |
Select-Object #{Name = 'Line'; Expression = {$_.Matches.Groups[1].Value}},
#{Name = 'Result'; Expression = {$_.Matches.Groups[2].Value}}
To get an explanation of the regex \b(in relation to any Facility [A-Z] Loan \[\s*(\d+%)\s*\] per cent. per annum);, please click here.

Answer 2

With a Regular Expression the solution is more efficient:
Get-Content .\contract.doc|
Where-Object {$_ -match 'in relation to any Facility.*\[([\d% ]+)\]'}|
ForEach-Object{
[PSCustomObject]#{
Name = $_
Value = $Matches[1].trim()
}
}
And I really should scroll down before posting a similar answer.

Try this:
EDIT:
$FinalTable = Get-Content .\Contract.doc |
select-string -pattern "in relation to any Facility" |
Select -Property #{Name = 'Name'; Expression = {$_.Line}} |
ForEach-Object {
$str = $_.Name
$start = $str.indexOf("[") + 1
$end = $str.indexOf("]", $start)
$length = $end - $start
$result = ($str.substring($start, $length)).trim()
#Creating a custom object to display in table format
$Obj = New-Object -TypeName PSCustomObject
Add-Member -InputObject $Obj -MemberType NoteProperty -Name Name -Value $str
Add-Member -InputObject $Obj -MemberType NoteProperty -Name Value -Value $result
$obj
}
$FinalTable
