使用 PowerShell 2.0 将多个 XML 文件合并为一个文件? [英] Merge multiple XML files into one using PowerShell 2.0?

问题描述

我有一个非常大的 XML 文件目录，其结构如下:

I have a directory of very large XML files with a structure as this:

file1.xml:

<root>
 <EmployeeInfo attr="one" />
 <EmployeeInfo attr="two" />
 <EmployeeInfo attr="three" />
</root>

file2.xml:

<root>
 <EmployeeInfo attr="four" />
 <EmployeeInfo attr="five" />
 <EmployeeInfo attr="six" />
</root>

现在我正在寻找一种简单的方法将这些文件 (*.xml) 文件合并到一个输出文件中:

Now I am looking for a simple way to merge these files (*.xml) files into one output file:

<root>
 <EmployeeInfo attr="one" />
 <EmployeeInfo attr="two" />
 <EmployeeInfo attr="three" />
 <EmployeeInfo attr="four" />
 <EmployeeInfo attr="five" />
 <EmployeeInfo attr="six" />
</root>

我正在考虑使用像这样的纯 XSLT:

I was thinking about using pure XSLT such as this one:

<xsl:transform version="1.0" 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="/">
    <Container>
      <xsl:copy-of select="document('file1.xml')"/>
      <xsl:copy-of select="document('file2.xml')"/>        
    </Container>
  </xsl:template>
</xsl:stylesheet>

这可行，但没有我想要的那么灵活.作为 PowerShell(第 2 版)的新手，我渴望学习在 PowerShell 中使用 XML 的新最佳实践，我想知道将 XML 文档结构合并为一个的最简单、最纯粹的 PowerShell 方式是什么?

This works but isn't as flexible as I want. Being a novice with PowerShell (version 2) eager to learn new best pracctices of working with XML in PowerShell I am wondering what is the simplest, purest PowerShell way of merging the structre of XML documents into one?

推荐答案

虽然 XSLT 方法很短，但 PowerShell 方法也是如此:

While the XSLT way to do this is pretty short, so is the PowerShell way:

$finalXml = "<root>"
foreach ($file in $files) {
    [xml]$xml = Get-Content $file    
    $finalXml += $xml.InnerXml
}
$finalXml += "</root>"
([xml]$finalXml).Save("$pwd\final.xml")
