我正在使用以下 XML、天气传感器结构。近期的目标是对这个结构进行排序，首先是传感器位置，然后是读取标签。我是一个在 XML 处理方面苦苦挣扎的新手！！！

好的，上面是 XLM，下面是我创建 XSL 转换文件的最佳尝试。我希望结果输出采用 XML 格式，与输入文件完全相同，但按传感器“位置”按 AZ 顺序排序并读取“标签”。经过大量阅读和谷歌搜索，这就是我想出的：

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="xml" indent="yes"/>

<xsl:template match="Sensors">
      <xsl:copy>    
    <xsl:apply-templates>
      <xsl:sort select="sensor/@location"/>
      <xsl:sort select="reading/label"/>
    </xsl:apply-templates>
      </xsl:copy>     
  </xsl:template>

<xsl:template match="node()|@*">
  <xsl:copy>
    <xsl:apply-templates select="node()|@*"/>
  </xsl:copy>
</xsl:template>

</xsl:stylesheet>

我正在使用 Microsoft XML 编辑器来测试我的代码。首先输出似乎没有输入文件的XML结构，也不完整，缺少传感器位置和其他级别及以上的项目。

我究竟做错了什么？

顺便说一句，在我弄清楚这一点后，我将使用经典 ASP 中的 XSL 转换文件来处理完整的 XML 文件。其中大部分已经在工作，当然除了排序过程。

从身份转换开始，然后覆盖要排序的元素的父级。您可以使用sortinxsl:apply-templates进行排序。

尝试这样的事情：

<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:output method="xml" indent="yes"/>

    <xsl:template match="/Sensors" >
        <xsl:copy>
            <xsl:apply-templates select="sensor">
                <xsl:sort select="@location"/>
            </xsl:apply-templates>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="sensor">
        <xsl:copy>
            <xsl:apply-templates select="@*" />
            <xsl:apply-templates select="reading">
                <xsl:sort select="@label"/>
            </xsl:apply-templates>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>

</xsl:stylesheet>
