正則運算式只找到開頭有空格的行

我的正則運算式適用于提取字串內容的各個區域，但是當我將其放入代碼中以獲取鍵值對的映射時，映射是錯誤的。有任何想法嗎？

重復內容如下所示，alarmID 右側不同，如 12-5000，鍵名如 LOAD_MEDIA：

..重復格式

出于某種原因，我回傳的 errorMap 甚至沒有接近正確。

這是應該在 $errorMap 中回傳鍵值對的代碼：

function Get-AlarmIDs{
    [cmdletbinding()]
    Param ([string]$fileContent)

    # create an ordered hashtable to store the results
    $errorMap = [ordered]@{}
    # process the lines one-by-one
    switch -Regex ($fileContent -split '\r?\n') {
        '[\t] ?<Key Name="(.*)">[\r?\n\s] ?<Value' { #match Key Name followed by Value  
            if(-not($matches[1] -match '[0-9]')) #use if it's not something like 57
            {
                $key = ($matches[1]).Trim()
            }
        }
        'AlarmID">(.*)<' {     #match AlarmID like 12-5700
                $errorMap[$key] = ($matches[1]).Trim()
        }
    }

    return $errorMap
}

我希望地圖看起來像這樣：

LOAD_MEDIA, 12-5000
LOAD_MEDIA2, 12-3
...

我知道我在 regex101.com 上的測驗表明我的鍵和值分別獲取了所需的行，但是當我將它們放在代碼中時，地圖全亂了：

[有序詞典：1]

[0]: [6,"12-5900"]   

我不確定它從哪里得到 6，而 12-5900 大約是重復序列中的最后一個，應該在 12-5900 之前回傳 5。

I'm using powershell 5.1 and Visual Studio code.

Update:

I'm trying to do this the xml way, and not sure how to get out of the xml what I need.

[xml]$xmlElm = (select-xml -xpath / -path $fileNamePath).node #Get-Content $fileNamePath 
$xmlElem.Configuration.'Key Name'.'Key Name'.Value  #this doesn't print anything...shouldn't it?

Update2:

Trying some more...

[xml]$xmldocument = Get-Content $fileNamePath
$tmp1 = $xmldocument.ChildNodes.selectNodes("*")
$tmp2 = $xmldocument.ChildNodes.selectNodes("*/Key")
$tmp3 = $xmldocument.Key.Value.AlarmID[0] #this is indexing into null
$tmp4 = $xmldocument.Key.Value #this is null

Update3:

I'm trying what's in Santiago's answer, but get blank Value in the map.

[xml]$xmldocument = Get-Content $fileNamePath
   
$result = foreach($key in $xmldocument.Configuration.Key.Key)
{
    [pscustomobject]@{
        Key = $key.Name
        Value = $key.Value.Where{$_Name -eq 'AlarmID'}.'#text'
    }
}

Gives (blank values)

[0]: @{Key=LOAD_MEDIA; Value=}
[1]: @{Key=Load_MEDIA2; Value=}

I'm not sure what's different.

Update4:

$result = foreach($key in $xmldocument.Configuration.Key.Key)
{
        [pscustomobject]@{
            Key = $key.Name
            Value = $key.Value 
        }
}
return $result

When I look at $result, it looks like this:

[0]: @{Key=LOAD_MEDIA; Value=System.Object[]}
[1]: @{Key=Load_MEDIA2; Value=System.Object[]}

uj5u.com熱心網友回復：

可能有比這更好的方法，但就目前而言，這應該可以幫助您獲得所需的內容。假設您已經在變數中加載了 XML，在這種情況下$xml：

$result = foreach($key in $xml.Configuration.Key.Key) {
    [pscustomobject]@{
        Key   = $key.Name
        Value = $key.Value.Where{$_.Name -eq 'AlarmID'}.'#text'
    }
}

$result使用有問題的 XML 應該如下所示：

Key         Value
---         -----
LOAD_MEDIA  12-5000
LOAD_MEDIA2 12-5001
