xml - 如何在PowerShell中自动创建XML的新元素？

Question

我有一个包含此内容的文本文件:

123asdf
abdfeef
22343sf
dfafdsf

该文件的内容正在更改。

我想创建一个xml文件，其中一个元素包含文本文件内容。

我试过了，但是所有内容都在同一个元素中:

$Getfile = Get-Content .\DeleteFile.txt
$TimeStamp = [System.TimeZoneInfo]::ConvertTimeBySystemTimeZoneId(
        (Get-Date), 'Taipei Standard Time')
$delete_file = @"
<?xml version="1.0" encoding="UTF-8"?>
    <Handling>
        <Deleted>
            <1>$Getfile</1>
        </Deleted>
        <TimeStamp>$TimeStamp</TimeStamp>
    </Handling>
"@
$delete_file | Out-File .\DeleteFile.xml

输出:

<?xml version="1.0" encoding="UTF-8"?>
<Handling>
    <Deleted>
        <1>123asdf abdfeef 22343sf dfafdsf</1>
    </Deleted>
    <TimeStamp>12/04/2019 17:49:06</TimeStamp>
</Handling>

我的期望是输出将是这样的:

<?xml version="1.0" encoding="UTF-8"?>
<Handling>
    <Deleted>
        <1>123asdf</1>
        <2>abdfeef</2>
        <3>22343sf</3>
        <4>dfafdsf</4>
    </Deleted>
    <TimeStamp>12/04/2019 17:49:06</TimeStamp>
</Handling>

谁能帮我吗？

内容进入同一元素，因为您没有创建新的XML元素。要添加元素，请创建一个XML对象并使用其CreateElement和AppendChild方法。像这样

# Skeleton document that is filled later
[xml]$d = @'
<Handling>
<Deleted />
<TimeStamp />
</Handling>
'@

# Dummy data, read these from a file instead    
$data = @('123asdf', 'abdfeef', '22343sf', 'dfafdsf')

# XPath selects the node under which new elements are added
$n = $d.SelectSingleNode('/Handling/Deleted')

# Loop through input data    
for($i=0; $i -lt $data.length; ++$i) {
    # Create new element, Element name is from loop counter
    $e = $d.CreateElement(($i+1).ToString())
    $e.InnerText = $data[$i]
    # Add the new node into document
    $n.AppendChild($e) | out-null
}
# Display the results.
$d.save([console]::out)

输出:

<?xml version="1.0" encoding="ibm850"?>
<Handling>
  <Deleted>
    <1>123asdf</1>
    <2>abdfeef</2>
    <3>22343sf</3>
    <4>dfafdsf</4>
  </Deleted>
  <TimeStamp />
</Handling>
