Iterating For-each loop on the condition provided in the variable in the XSLT
问题
我想让我的for-each循环在变量中提供的条件上工作。
如果Record_Counter的值为7，则for_each应该迭代7次。
注意：我已经创建了一个名为Counter的变量来存储Record_Counter的值。
请查找我尝试过的XSLT代码，但它没有给我想要的结果。
<xsl:variable name="Counter" select="Element[1]/@Record_Counter" />
<xsl:for-each select="$Counter">
<itemGroup ref="ValTechnique">
<reportItem key="yes">
<itemValue>
<xsl:value-of select="@Reporting"/>
</itemValue>
</reportItem>
<reportItem>
<itemValue>
<xsl:value-of select="@Valuation"/>
</itemValue>
</reportItem>
</itemGroup>
</xsl:for-each>
英文:
I want my for-each loop to work on the condition provide in the variable defined.
If Record_Counter has value 7 in it, then for_each should iterate for 7 times.
Note: I have created the variable Counter to store Record_Counter value.
Please find XSLT code which I tried but it is not giving me desired result.
<xsl:variable name= "Counter" select="Element[1]/@Record_Counter" />
<xsl:for-each select="$Counter">
<itemGroup ref="ValTechnique">
<reportItem key="yes">
<itemValue>
<xsl:value-of select="@Reporting"/>
</itemValue>
</reportItem>
<reportItem>
<itemValue>
<xsl:value-of select="@Valuation"/>
</itemValue>
</reportItem>
</itemGroup>
</xsl:for-each>

在XSLT 2及更高版本中，您当然可以使用1 to $var表达式，例如<xsl:for-each select="1 to xs:integer($Counter)">，但在for-each中，上下文项目是当前处理的整数值，因此任何尝试选择节点，例如<xsl:value-of select="@Reporting"/>都不会起作用，您需要在for-each之前添加<xsl:variable name="context-node" select="."/>，然后在for-each内部使用<xsl:value-of select="$context-node/@Reporting"/>。
这可能仍然不够，因为您不太可能希望输出相同的内容 $Counter 次，但您尚未展示输入和所需输出，因此我无法确定您需要/想要进行的其他更改。
英文:
In XSLT 2 and later you can certainly use a 1 to $var expression e.g. <xsl:for-each select="1 to xs:integer($Counter)"> but that way inside of the for-each the context item is the currently processed integer value so any attempt to select nodes with e.g. <xsl:value-of select="@Reporting"/> will not work, you would need to put e.g. <xsl:variable name="context-node" select="."/> before the for-each and then use e.g. <xsl:value-of select="$context-node/@Reporting"/> inside the for-each.
That might still not suffice as it is unlikely you want to output the same stuff $Counter times but you haven't show your input and wanted output so I can't tell what other changes you need/want.
