这是使用XSLT排序的正确方法吗？

基本上发生的事情是XML节点本身并没有改变位置。所以我认为我的XSLT遗漏了一些东西。

XSLT：

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:asp="http://test.com/asp"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl">

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

    <xsl:template match="root">
        <root>
            <xsl:apply-templates select="asp:TableRow">
                <xsl:sort select="@ID" data-type="text" order="ascending"/>
            </xsl:apply-templates>
        </root>
    </xsl:template>
</xsl:stylesheet>

XML：

<?xml version="1.0" encoding="utf-8"?>
<Root xmlns:asp="http://test.com/asp" xmlns:meta="http://test.com/meta" xmlns:cc1="http://test.com/cc1">
  <asp:TableRow ID="A02">

2 个答案:

答案 0 :(得分：2)

提供的代码有两个明显的问题：

  1. 代码中唯一的模板匹配root，但在提供的XML元素中根本没有root元素 - 因此根本不会选择执行此模板

  2. 提供的XML文档中的元素没有文本节点子节点。由于提供的XSLT代码中没有任何其他模板，因此在处理XML文档时仅使用内置的XSLT模板。它们的作用是仅将文本节点复制到输出 - 因此不会产生任何输出。

    3. <强>解决方案：

    1. 将match='root'更改为match='Root'。

    2. 添加标识规则，以便复制每个节点。

      3. 对您的代码应用了这两个更正后，它变为：

      <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:asp="http://test.com/asp"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl">

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

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

    <xsl:template match="Root">
        <root>
            <xsl:apply-templates select="asp:TableRow">
                <xsl:sort select="@ID" data-type="text" order="ascending"/>
            </xsl:apply-templates>
        </root>
    </xsl:template>
</xsl:stylesheet>

      并应用于提供的XML文档：

      <Root xmlns:asp="http://test.com/asp" xmlns:meta="http://test.com/meta" xmlns:cc1="http://test.com/cc1">
  <asp:TableRow ID="A02">

    </asp:TableCell>
    <asp:TableCell />
    <asp:TableCell />
    <asp:TableCell />
  </asp:TableRow>
</Root>

      生成了想要的，正确的（已排序的）结果：

答案 1 :(得分：0)

@Dimitre：再次感谢你帮助我。你有书还是什么？我买了我不得不改变代码隐藏。这是改变：

Dim xsltPath As String = Server.MapPath(xsltFileName3)

Dim sortXmlDoc As Xsl.XslCompiledTransform = New Xsl.XslCompiledTransform(True)
sortXmlDoc.Load(xsltPath)
Dim output = sortXmlDoc.OutputSettings

Dim saveWriter As XmlWriter = XmlWriter.Create(truePath, output)
sortXmlDoc.Transform(markup, saveWriter)
saveWriter.Close()

变量“markup”是一个XmlDocument。在写入XmlWriter之后，我发现我无法做markup.Save。它会再次以错误的顺序将数据写入XML文件。由于代码隐藏的行为方式，我对XSLT稍作改动。

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:asp="http://test.com/asp"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl">

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

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

    <xsl:template match="Root">
        <Root xmlns:asp="http://test.com/asp" xmlns:meta="http://test.com/meta" xmlns:cc1="http://test.com/cc1">
            <xsl:apply-templates select="asp:TableRow">
                <xsl:sort select="@ID" data-type="text" order="ascending"/>
            </xsl:apply-templates>
        </Root>
    </xsl:template>

</xsl:stylesheet>
