Question

我正在使用以下XML，天气传感器结构。目前的最终目标是对此结构进行排序，首先是传感器位置，然后是读取标签。我是一个苦苦挣扎的XML处理新手!!!

好的，上面是XLM，下面是我尝试创建XSL转换文件的最佳方法。我希望得到的输出是XML格式，与输入文件完全相同，但是按传感器“location”和读取“Label”以A-Z顺序排序。经过大量的阅读和谷歌搜索，这就是我的想法：

<?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，也没有完整，传感器位置和级别及以上的其他项目都缺失。

我做错了什么？

顺便说一句，在我弄清楚之后，我将使用经典ASP中的XSL转换文件处理完整的XML文件。除了排序过程之外，其中大部分已经有效了。

Answer 1

以identity transform开头，然后覆盖要排序的元素的父级。您可以使用sort中的xsl:apply-templates进行排序。

Answer 2

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>
