XML - 根据匹配条件删除嵌套元素然后重命名剩余元素？答案

【问题标题】：XML - Delete nested element based on matching condition then rename remaining elements?XML - 根据匹配条件删除嵌套元素然后重命名剩余元素？
【发布时间】：2019-05-23 03:16:12
【问题描述】：

我有一个 XML 文件，我想根据匹配条件删除特定元素，然后重命名/重新编号剩余的元素。

<AudioTracks>整体可以包含多个不同的<ScannedTrack>和多个in内

<AudioTracks>
 <AudioTrack>
  <ScannedTrack>

包含读取的输入音轨

<AudioTracks>
 <AudioTrack>

包含输出的音频编码设置

我想根据输入进行以下更改：

If <ScannedTrack>
    <TrackNumber>1</TrackNumber> AND <Codec>262144</Codec>
AND If <ScannedTrack>
    <TrackNumber>2</TrackNumber> AND <Codec>8192</Codec>

然后删除<AudioTrack>元素，其中<TrackNumber>1

然后

IF <TrackNumber>2 exist rename as <TrackNumber>1
IF <TrackNumber>3 exist rename as <TrackNumber>2
IF <TrackNumber>4 exist rename as <TrackNumber>3

（等到无穷大）

即然后任何后续轨道向后移动 1 个轨道 ID（即原始轨道 3 现在变为新轨道 2，原始轨道 4 现在移动到新轨道 3 等）

任何人都可以根据上述要求提供修改 XML 文件的解决方案吗？

这是原始 XML 供参考：

      <xsl:delete>AudioTrack</xsl:copy>
  </xsl:template>

</xsl:stylesheet>

我的编码很差，但我也不知道如何为其余曲目运行 for 循环。

编辑：更正错误，修复 xml 文件

【问题讨论】：

这个还是蛮难理解的。您的 XML（您应该将其减少到证明问题所需的最低限度）的轨道编号为 1、2、1、1。此外，您制定条件的方式也是模棱两可的。
你的代码在哪里？照原样，这只是一个需求转储，它将照此关闭。
@michael.hor257k 修复了 TrackNumber 问题，现在是 1,2,3,4。 “删除 1 的元素”不明确？这意味着删除整个 AudioTrack 元素和其中匹配/相关 TrackNumber 的所有节点。
@michael.hor257k 我也没有减少 XML，因为我之前在其他地方做了一个不同的问题，另一个用户建议我不应该这样做，因为我可能会在代码中进一步导致未实现的问题，所以最好保持完整。
@michael.hor257k 谢谢，我会看看这个。您能否也看到这个问题以了解类似但稍微困难的要求stackoverflow.com/questions/56268237 ？
