我怎样才能完成这样的事情:
PS /home/nicholas/powershell>
PS /home/nicholas/powershell> $date=(Get-Date | ConvertTo-Xml)
PS /home/nicholas/powershell>
PS /home/nicholas/powershell> $date
xml Objects
--- -------
version="1.0" encoding="utf-8" Objects
PS /home/nicholas/powershell>
PS /home/nicholas/powershell> $date.OuterXml
<?xml version="1.0" encoding="utf-8"?><Objects><Object Type="System.DateTime">12/12/2020 2:43:46 AM</Object></Objects>
PS /home/nicholas/powershell>
但是,相反,读取文件?
如何使用 using 加载/导入/读取/转换xml
文件以进行ConvertTo-Xml
解析?Select-Xml
Xpath
PS /home/nicholas/powershell>
PS /home/nicholas/powershell> $xml=ConvertTo-Xml ./bookstore.xml
PS /home/nicholas/powershell>
PS /home/nicholas/powershell> $xml
