how use break statement on powershell "switch -regex -file"?

i'm using the next function to parse one ini file.

I have one problem that i don't know how to solve:

If one match is found, break loop and read next line.

I know that i can put break to do this. But, break exit of all switch code. ¿?

I suppose it's a special scenario when using switch with regex to parse a file.

¿How can i do to not parse same line in two code blocks?

See in the output:

`Comment ; Parameters that are strings are specified parameter=string, like this:`
`Key ; Parameters that are strings are specified parameter=string, like this:`

and

`Comment ; Parameters that are numbers are specified parameter=number, like this:` 
`Key ; Parameters that are numbers are specified parameter=number, like this:`

Thanks

    function Get-IniContent ($filePath)  
    {  
        $ini = @{}   
        switch -regex -file $FilePath   
        {   
            "^\[(.+)\]$" # Section   
            {   
                $section = $matches[1]   
                $ini[$section] = @{}   
                $CommentCount = 0   
                Write-Host "Section $section"  
            }   
            "^(;.*)$" # Comment   
            {   
                if (!($section))   
                {   
                    $section = "No-Section"   
                    $ini[$section] = @{}   
                }   
                $value = $matches[1]   
                $CommentCount = $CommentCount + 1   
                $name = "Comment" + $CommentCount   
                $ini[$section][$name] = $value   
                Write-Host "Comment $value"  
            }    
            "(.+?)\s*=\s*(.*)" # Key   
            {   
                if (!($section))   
                {   
                    $section = "No-Section"   
                    $ini[$section] = @{}   
                }   
                $name,$value = $matches[1..2]   
                $ini[$section][$name] = $value   
                Write-Host "Key $name=$value"  
            }   
            default  
            {              
                # Next line causes NullArray error  
                #$line=$matches[1]  
                Write-Host "Strange line $line"  
            }  
        }   

        return $ini  
    }  

    $iniFile=Get-IniContent (Join-Path (Split-Path -parent $MyInvocation.MyCommand.Path) "test.config")   

This it's a sample ini file:

; Blank lines also do no harm

:Bad Line

And this it's script output:
