Need a little help to find a pattern in a string-CodePudding

I am reading an XML file that contains a range of versions for an example: 8.6.22.0-8.6.24.999

My goal is to know if each one of the entries contains a range only for 8.6.22-8.6.22 and does not contain version 8.6.21/3/4 in any place in the string. I don't care if after the dot there are numbers (8.6.22.000, 8.6.22.999) I tried to do it, its working for (8.6.20.0-8.6.22.999 or 8.6.1000.0000-8.6.4000.9999) but not for (8.6.22.0-8.6.24.999)

This is part of my code: there is a function that read all the version from the XML and fill the $versions I run in a loop for each one of the versions and compare to 8.6.22*

$compareversion = "8.6.22*"
if (![string]::IsNullOrEmpty($versions)) {
    Write-host "Versions range (Manifest):"   
    foreach ($v in $versions) {
    
        if ($v -notlike $compareversion) {
            Write-host $v -ForegroundColor Red
        
        }
        else {
            Write-host $v
               
        }  
    }
    Write-Host
}

The output is:

Versions range (Manifest):
8.6.22.607-8.6.22.999
8.6.22.0-8.6.22.999999
8.6.22.0-8.6.22.999999
8.6.22.607-8.6.22.999

8.6.22.0-8.6.22.999
8.6.22.0-8.6.22.999
8.6.22.0-8.6.24.99999999
8.6.22.0000-8.6.22.9999
8.6.22.0000-8.6.22.9999
8.6.1000.0000-8.6.4000.9999
8.6.22.607-8.6.22.999
8.6.22.000-8.6.24.999
8.6.22.000-8.6.22.999
8.6.22.1-8.6.22.9999
8.6.22.0000-8.6.22.9999
8.6.22.1-8.6.22.9999
8.6.20.0-8.6.22.999
8.6.22.001-8.6.22.999

CodePudding user response：

You can use the Version class to help you compare the beginning and end ranges from each line. Since this class implements IComparable, it makes it really easy to check if a version is a above or below the target range.

Assuming all these ranges are stored in $allRanges:

$allRanges | ForEach-Object {
    $start, $end = [version[]] $_.Split('-')
    if($start -ge '8.6.22' -and $end -lt '8.6.23') {
        return Write-host "In Range: $_" -ForegroundColor Green
    }

    Write-Host "Out of Range: $_" -ForegroundColor Red
}

The result using this code is:

In Range: 8.6.22.607-8.6.22.999
In Range: 8.6.22.0-8.6.22.999999
