Question

我有一个大约有10,000行的XML文件，我想将一些数据提取到CSV文件中。

我遇到的问题是提取id属性和联盟名称标签的内部文本。如果有人能够阐明为什么ID没有显示以及如何获取innertext那将是非常有帮助的。

当前代码

$xml.selectNodes('//playeralliance') |
  select alliancename.id, allianceticker, alliancetaxrate

输出

PS C:\Users\jon> $xml.selectNodes('//playeralliance') | select alliancename.id, alliancename, alliancetag, alliancetax

alliancename.id alliancename alliancetag alliancetax
--------------- ------------ ----------- -----------
                alliancename DaVS           0.01           
                alliancename DaVS           0.01           
                alliancename DaVS           0.01           
                alliancename DaVS           0.01           
                alliancename DaVS           0.01           
                alliancename DaVS           0.01

过去的代码示例

[xml]$xml = Get-Content 'C:\Users\jhold\Desktop\Illyriad Data\sample.xml';

$xml.towns.town.player;

foreach($item in $xml.playeralliance)
{
    $allianceName = $item
    #$allianceID = $item.id
    #$allianceTicker = $item.allianceticker
    #$allianceTax = $item.alliancetax

    Write-host "Name: " $allianceName 
    #Write-host "ID: " $allianceID
    #Write-host "Ticker: " $allianceTicker
    #Write-host "Tax: " $allianceTax
}

Answer 1

使用calculated properties：

$xml.SelectNodes('//playeralliance') |
  Select-Object @{n='allianceid';e={$_.alliancename.id}},
                @{n='alliancename';e={$_.alliancename.'#text'}},
                @{n='allianceticker';e={$_.alliancetag}},
                @{n='alliancetaxrate';e={$_.alliancetax}}

Answer 2

如果我没记错的话，那就是powershell v3 +

PS C:\Users\joshua> [xml]$xml = Get-Content C:\Users\joshua\Desktop\sample.xml

$xml.town.player

$xml.town.player.playername.id

$xml.town.player.playername.'#text'

playername playerrace playeralliance
---------- ---------- --------------
playername Elf        playeralliance
10
MyName

Answer 3

利用扩展属性......它对我有用。

router.get('/hello', (req, res) => {
    res.send('This get executed');
});
router.get('/hello', (req, res) => {
    res.send('This will NOT get executed since you are ending the response with res.send in the route above');
});

从XML
