我想知道是否可以在 XSLT 中嵌套动态节点集,如果可以,如何使用 xPath 选择它们。这是一项更大任务的一部分。我只展示我坚持的部分。

这是我的 XSLT:

<xsl:variable name="Tables">
  <xsl:for-each select="Table">
    <xsl:variable name="TableName" select="Name | @Name"/>
    <xsl:variable name="Columns">
      <xsl:for-each select="Column">
        <xsl:variable name="ColumnName" select="Name | @Name"/>
        <xsl:variable name="Type" select="Type | @Type"/>
        <Column>
          <Name>
            <xsl:value-of select="$ColumnName"/>
          </Name>
          <Type>
            <xsl:value-of select="$Type"/>
          </Type>
        </Column>
      </xsl:for-each>
    </xsl:variable>
    <Table>
      <Name>
        <xsl:value-of select="$TableName"/>
      </Name>
      <Columns>
        <xsl:value-of select="$Columns"/>
      </Columns>
    </Table>
  </xsl:for-each>
</xsl:variable>

<xsl:for-each select="msxsl:node-set($Tables)/Table">
  Table Name: <xsl:value-of select="Name"/>
  <xsl:for-each select="msxsl:node-set(Columns)/Column" xml:space="preserve">
    Column Name: <xsl:value-of select="Name"/>
    Column Type: <xsl:value-of select="Type"/>
  </xsl:for-each>
</xsl:for-each>

这是我的 XML:

  <Table Name="Product">
    <Column Name="ProductID" Type="int"/>
    <Column Name="Name" Type="string"/>
    <Column Name="Cost" Type="decimal"/>
    <Column Name="Area" Type="decimal?"/>
  </Table>
  <Table Name="Market">
    <Column Name="MarketID" Type="int"/>
    <Column Name="Name" Type="string"/>
    <Column Name="MinimumASP" Type="double"/>
    <Column Name="MaximumASP" Type="double"/>
  </Table>

这是我目前得到的输出:

  Table Name: Product
  Table Name: Market

这就是我想要得到的:

  Table Name: Product
  Column Name: ProductID
  Column Type: int
  Column Name: Name
  Column Type: string
  Column Name: Cost
  Column Type: decimal
  Column Name: Area
  Column Type: decimal?
  Table Name: Market
  Column Name: MarketID
  Column Type: int
  Column Name: Name
  Column Type: string
  Column Name: MinimumASP
  Column Type: double
  Column Name: MaximumASP
  Column Type: double

可以以更简单的方式产生想要的结果,无需创建任何临时树

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output method="text"/>
 <xsl:strip-space elements="*"/>

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

 <xsl:template match="@*">
  <xsl:value-of select=
   "concat(name(..), ' ', name(), ': ', .)"/>
  <xsl:text>&#xA;</xsl:text>
 </xsl:template>
</xsl:stylesheet>

当此转换应用于提供的 XML 文档时(包装在单个顶部元素中以使其格式正确):

<t>
    <Table Name="Product">
        <Column Name="ProductID" Type="int"/>
        <Column Name="Name" Type="string"/>
        <Column Name="Cost" Type="decimal"/>
        <Column Name="Area" Type="decimal?"/>
    </Table>
    <Table Name="Market">
        <Column Name="MarketID" Type="int"/>
        <Column Name="Name" Type="string"/>
        <Column Name="MinimumASP" Type="double"/>
        <Column Name="MaximumASP" Type="double"/>
    </Table>
</t>

产生了想要的正确结果:

Table Name: Product
Column Name: ProductID
Column Type: int
Column Name: Name
Column Type: string
Column Name: Cost
Column Type: decimal
Column Name: Area
Column Type: decimal?
Table Name: Market
Column Name: MarketID
Column Type: int
Column Name: Name
Column Type: string
Column Name: MinimumASP
Column Type: double
Column Name: MaximumASP
Column Type: double
