使用 LF 和 UTF-8 在 powershell 中创建 XML 失败

Question

过去几天我一直在尝试创建一个 Powershell 脚本，该脚本将创建一个 XML 文件，其中包含表示时间的 2 个字段。问题是创建的 XML 是 CR LF with UTF-8 BOM 而我需要的是 LF with UTF-8。

编辑 - 遵循“LotPings”的建议，添加代码确实将 XML 更改为 Unix(FL)，但它仍然在 UTF8-BOM 上，但它给我带来了问题。 如何将其从 UTF8-BOM 更改为 UTF8？

我从未使用过 Powershell，也不知道如何实现。

# Set The Formatting
$xmlsettings = New-Object System.Xml.XmlWriterSettings
$xmlsettings.Indent = $true
$xmlsettings.IndentChars = "    "
$hour = (Get-Date).hour
$day = (Get-Date).dayofweek

# Checking If Its Too Late
If ($day -eq "Saturday" -and $hour -lt "8")
{
    $hour = "00"
}
else
{
    if ($day -ne "Saturday" -and $hour -lt "7")
    {
        $hour = "00"
    }
}


# Set the File Name Create The Document

$XmlWriter = [System.XML.XmlWriter]::Create("S:\NowPlaying\Ch0-News13.xml", $xmlsettings)


# Start the Root Element
$xmlWriter.WriteStartElement("track")

    $xmlWriter.WriteElementString("name",$hour.ToString()+":00" + "News Flash of")
    $xmlWriter.WriteElementString("artist","News Channel")

$xmlWriter.WriteEndElement() # <-- End <Track> 

# End, Finalize and close the XML Document
$xmlWriter.WriteEndDocument()
$xmlWriter.Flush()
$xmlWriter.Close()

扩展您的$xmlsettings：

$xmlsettings.NewLineChars = "`n"

用[0A]标记的示例输出（十六进制）0A：

> Format-Hex .\Ch0-News13.xml

           00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
