powershell - select-xml不返回任何结果

我正在尝试使用powershell命令select-xml从xml文件中选择数据。当我在下面运行命令时，没有结果或错误返回。我希望版本列表会返回到屏幕。这怎么了

PS C:\> select-xml -path "C:\t.xml" -xpath "//edition" | foreach {$_.node.InnerXML}
PS C:\>

XML文件(C:\ t.xml)为:

 <?xml version="1.0" encoding="utf-8"?>
  <Book>
    <projects>
      <project name="Book1" date="2009-01-20">
        <editions>
           <edition language="English">En.Book1.com</edition>
           <edition language="German">Ge.Book1.Com</edition>
           <edition language="French">Fr.Book1.com</edition>
           <edition language="Polish">Pl.Book1.com</edition>
        </editions>
      </project>
    </projects>
  </Book>

最佳答案

做到这一点的另一种方法是:

PS H:\> $xml = ([xml](Get-Content -Path C:\scripts\t.xml)).Book.Projects.Project
PS H:\> $xml.editions | select -ExpandProperty Edition
