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。我只是展示了我坚持的部分。
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
这是我想要的:
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
答案 0 :(得分:0)
想要的结果可以通过更简单的方式生成,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>
</xsl:text>
</xsl:template>
</xsl:stylesheet>
将此转换应用于提供的XML文档(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
