我正在使用以下XML天氣傳感器結構。目前的目標是對這種結構進行分類，首先通過傳感器位置，然後通過閱讀標籤。我是一個掙扎的XML處理新手！使用XSL轉換將XML轉換爲XML排序

好吧，上面是XLM，下面是我最好的嘗試創建一個XSL轉換文件。我希望得到的輸出爲XML格式，與輸入文件完全相同，但是按傳感器「位置」以A-Z順序排序並閱讀「標籤」。經過大量的閱讀和搜索谷歌，這是我想出了：
<?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>
我使用的是微軟的XML編輯器來測試我的代碼。首先輸出似乎沒有輸入文件的XML結構，並且它還沒有完成，傳感器位置和其他項目在上一級和下一級缺失。
我在做什麼錯？
順便說一句，我得到這個想法後，我將使用經典ASP中的XSL轉換文件處理完整的XML文件。大部分工作已經開始，除了排序過程。
