Question

我有一个这种格式的文本文件。

Configuration
;
;   Authors: James

;   Accepted

Name
    James
Class
    A2
Birthday
    1 September 1982
Family Member
    4
First Year Salary Number
    100 USD
Second Year Salary Number
    150 USD
Company Name
    Unlimited Company
Total Salary Number
    1300 USD
ExpectedSalaryNumber
    FY:350 USD
    SY:450 USD
    TS:2000 USD

如果标题包含"Salary Number"和"SalaryNumber"，我想删除整个内容，还要删除标题"Configuration.... "，并在删除后输出文件。我的期望输出文件是这样的

Name
    James
Class
    A2
Birthday
    1 September 1982

    4
Company Name
    Unlimited Company

我尝试了这个，但是它只是输出我删除的内容。任何人都可以帮助我。非常感谢。

$name = $false 
& { 
  switch -regex -file .\Configuration.TXT {
    '^*Salary Number*, ^*SalaryNumber*' { $name = $true; continue }
    '^\s' { if ($name) { $_.Trim() }}
    '^\S' { if ($name) { return } }
  }
} | Remove-Item | Out-File .\Output.txt

此示例仍然使用switch，但是这次使用它来确定对每一行的处理方式，之后仅输出那些感兴趣的行（非薪水，非标题）：

# These variables are changed to true if the line is a header or a salary
$header = $false
$salary = $false
Get-Content .\Configuration.TXT | ForEach-Object {
    # The header flag is reset each time as the header checks are made first
    $header = $false
    # The $salary variable is only reset back to false when a new header is reached, provided it does not contain Salary\s*Number

    # Use switch to find out what type of line it is
    switch -regex ($_)
    {
        '^Configuration' # Beginning with Configuration 
        {
            $header = $true
        }
        '^;' # Beginning with semicolon 
        {
            $header = $true
        }
        # Data lines begin with a space
        # move to the next line - do not alter $salary variable
        '^\s'  
        {
            continue
        }
        # If Salary Number is found set the flag
        'Salary\s*Number' {
            $salary = $true
        }
        # This is only reached once it has been determined the line is 
        # not a header
        # not a salary header line
        # not a data line 
        # i.e. only headers that are not Salary
        # this resets the flag and makes lines eligible for output
        default {
            $salary = $false
        }

    }
    # Only output lines that are not Salary and not headers
    if ($salary -eq $false -and $header -eq $false) {
        $_
    }
} | Out-File .\Output.txt
