Powershell:在特定的当前同级元素之后添加新的 XML 元素 [英] Powershell : Add new XML element after a specific current sibling element

问题描述

我有一个 xml 列表，我希望在 下添加一个新的子元素.我已经能够将子元素附加到游戏节点块的末尾，但为了命名标准，我需要将它作为图像的兄弟元素插入到图像元素之后.

I have an xml list that I wish to add a new child element to under <game>. I have been able to appended the child element to the end of the game node block but for naming standards I need to insert it after the image element as a sibling of image.

<image>
<marquee> 

XML 文档:

<?xml version="1.0" encoding="UTF-8"?>
  <gameList>
      <game id="2758" source="theGamesDB.net">
          <path>./Zelda II - The Adventure of Link (USA).zip</path>
          <name>Zelda II - The Adventure of Link (USA)</name>
          <desc>Removed description for example</desc>
          <image>./boxart/Zelda II - The Adventure of Link (USA).png</image>

          <genre>Action</genre>
          <players>1</players>
      </game>
</gamelist>

我的代码在代码块的末尾附加一个选取框子元素.注意:这是一个循环遍历大量游戏的 for each 循环.为简单起见，我删除了创建选取框路径位置的代码并将其硬编码.

My code to append a marquee child element at the end of the code block. Note: This is a for each loop that cycles through a huge list of games. For simplicity I have taken out the code that creates the marquee path location and hard coded it in.

#Set the name of the game list 
    $InputXML = "gamelist.xml"
    $OutputXML = "MODgamelist.xml"

    #Load the existing document
    [xml]$xml = Get-Content $InputXML

    foreach($game in $xml.gamelist.game)
    {

    #Set Marquee Path
    $marqueelPath = "./Zelda II - The Adventure of Link (USA).png"

    #Add marquee node to game node parent
    $marqueeElement = $xml.CreateElement("marquee") 
    $marqueeElement.InnerText = $marqueelPath
    $game.AppendChild($marqueeElement)   

    }

    #Output
    $xml.save($OutputXML)

经过一番挖掘，我想出了这段代码，在图像之后插入新的子元素，但它出错了.如何正确选择图像节点然后在其后插入?

After some digging I have come up with this code to insert the new child element after image but it errors out. How do I correctly select the image node then insert after it?

$imageElement = $game.SelectSingleNode('//image')
$game.InsertAfter($marqueeElement, $imageElement)

错误:

Exception calling "InsertAfter" with "2" argument(s): "The reference node is not a child of this node."
At line:1 char:1
+ $game.InsertAfter($marqueeElement, $imageElement)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : DotNetMethodException

提前致谢.

推荐答案

我正在阅读 MSDN 文档并找到了一个解决方案.https://msdn.microsoft.com/en-us/library/k44daxya.aspx

I was reading through the MSDN documentation and worked out a solution. https://msdn.microsoft.com/en-us/library/k44daxya.aspx

由于所有游戏节点块的布局都相同，我实际上可以通过数组编号调用参考节点.

With all the Game Node blocks being identical in layout, I can actually call the reference node by array number.

#Add marquee node to game node parent
$marqueeElement = $xml.CreateElement("marquee") 
$marqueeElement.InnerText = $marqueelPath
$game.InsertAfter($marqueeElement, $game.ChildNodes[3])
