Это правильный способ сортировки с использованием XSLT?

В основном происходит то, что сами узлы XML не меняют своего положения.Поэтому я решил, что в моем XSLT чего-то не хватает.

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">

Есть две очевидные проблемы с предоставленным кодом :

  1. Единственный шаблон в коде соответствует root, но нет rootэлемент вообще в предоставленном элементе XML - поэтому этот шаблон вообще не выбран для выполнения.

  2. Элементы в предоставленном документе XML не имеют дочерних текстовых узлов.Так как в предоставленном коде XSLT нет другого шаблона, для обработки документа XML используются только встроенные шаблоны XSLT.Их эффект заключается в копировании на вывод только текстовых узлов - поэтому ничего не выводится в качестве вывода.

Решение :

  1. Измените match='root' на match='Root'.

  2. Добавьте правило идентификации, чтобы копировать каждый узел.

После применения этих двух исправлений к вашему коду он становится : 

<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>

и при применении к предоставленному документу XML : 

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

@ Димитр: Еще раз спасибо за помощь.У вас есть книга или что-то?Я бы купил это.Я должен был внести изменения в коде позади.Это изменение: 

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()

Переменная "разметка" является XmlDocument.После записи в XmlWriter я обнаружил, что не могу сделать разметку. Сохранить.Он запишет данные в файл XML снова и в неправильном порядке.Из-за поведения кода, я внес небольшое изменение в 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="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>
...
