是否可以在 xslt 中嵌套动态节点集?
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。我只展示我所坚持的部分。
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($Tables)/Table">
Table Name: <xsl:value-of select="Name"/>
<xsl:for-each select="msxsl:node-set(Columns)/Column" xml:space="preserve">
Column Name: <xsl:value-of select="Name"/>
Column Type: <xsl:value-of select="Type"/>
</xsl:for-each>
</xsl:for-each>
这是我的 XML:
<Table Name="Product">
<Column Name="ProductID" Type="int"/>
<Column Name="Name" Type="string"/>
<Column Name="Cost" Type="decimal"/>
<Column Name="Area" Type="decimal?"/>
</Table>
<Table Name="Market">
<Column Name="MarketID" Type="int"/>
<Column Name="Name" Type="string"/>
<Column Name="MinimumASP" Type="double"/>
<Column Name="MaximumASP" Type="double"/>
</Table>
这是我当前得到的输出:
Table Name: Product
Table Name: Market
这是我想要得到的:
Table Name: Product
Column Name: ProductID
Column Type: int
Column Name: Name
Column Type: string
Column Name: Cost
Column Type: decimal
Column Name: Area
Column Type: decimal?
Table Name: Market
Column Name: MarketID
Column Type: int
Column Name: Name
Column Type: string
Column Name: MinimumASP
Column Type: double
Column Name: MaximumASP
Column Type: double
I'd like to know if it is possible to nest dynamic node sets in XSLT and if so, how to select them using xPath. This is part of a bigger task. I'm only showing the part that I'm stuck on.
This is my XSLT:
<xsl:variable name="Tables">
<xsl:for-each select="Table">
<xsl:variable name="TableName" select="Name | @Name"/>
<xsl:variable name="Columns">
<xsl:for-each select="Column">
<xsl:variable name="ColumnName" select="Name | @Name"/>
<xsl:variable name="Type" select="Type | @Type"/>
<Column>
<Name>
<xsl:value-of select="$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>
This is my 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>
This is the output I'm currently getting:
Table Name: Product
Table Name: Market
This is what I'd like to get:
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

可以通过更简单的方式生成所需的结果,并且无需创建任何临时树:
当此转换应用于提供的 XML 文档时(包装在单个顶部元素使其格式良好):
产生了想要的正确结果:
The wanted result can be produced im a much simpler way and there is no need to create any temporary trees:
When this transformation is applied on the provided XML document (wrapped in a single top element to make it well-formed):
the wanted, correct result is produced:
