[问题求助] [已解决]powershell 中 getElementById不起作用

if ($true){}# == ($true){}# goto ___yiwuyun
<#BeginBatOperation#
:___yiwuyun
@echo off&setlocal&cls
(echo $yiwuyun_fileName="%~f0"&echo $strPath="%~dp0"&type "%~f0")|powershell -command -
pause
exit/b 0
#EndBatOperation#>

<#StartPowerShell#>
$xml=@"
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<root>
<bat001 name="bat1" id="bat1">
data
</bat001>
</root>
"@
$doc=New-Object -TypeName System.Xml.XmlDocument;
$doc.LoadXml($xml);
###$doc.GetElementById("bat1");  这一句不起作用
$doc.GetElementsByTagName("bat001");### 这一句正常

<#EndPowerShell#>
