这是使用 XSLT 进行排序的正确方法吗？

Question

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 缺少一些东西。

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">

代码隐藏：

For Each deleteChild As XmlNode In rootDoc.DocumentElement.ChildNodes
    rootDoc.DocumentElement.RemoveChild(deleteChild)
Next

'List (Of XMLNode)'
For Each markupElem As XmlElement In allNodes
    rootDoc.DocumentElement.AppendChild(markupElem)
Next

'List (Of XMLNode)'
For Each markupElem As XmlElement In nodesToMove
    rootDoc.DocumentElement.AppendChild(markupElem)
Next

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

Dim saveWriter As XmlTextWriter = New XmlTextWriter(truePath, Nothing)
sortXmlDoc.Transform(rootDoc, saveWriter)
saveWriter.Close()

Answer 1

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 - 因此根本没有选择执行此模板。

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 文档时只使用内置的 XSLT 模板。它们的效果是仅将文本节点复制到输出 - 因此不会产生任何输出。

解决方案：

1. 将match='root' 更改为match='Root'。

2. 添加身份规则，这样每个节点都会被复制。

将这两个更正应用于您的代码后，它就变成了：

<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>

当应用于提供的 XML 文档时：

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

产生了想要的、正确的（排序的）结果：

Answer 2

@Dimitre：再次感谢您帮助我。你有书吗？我会买的。我不得不对代码隐藏进行更改。这是变化：

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“标记”是一个 XmlDocument。写入 XmlWriter 后，我发现我无法执行 markup.Save。它会以错误的顺序再次将数据写入 XML 文件。由于代码隐藏的行为方式，我对 XSLT 做了一点改动。
