XSLT V1 For Each循环使用generate_id和key不循环

时间：2018-03-27 16:02:30

标签： xml xslt

我有一个XML文档，我正在使用XSLT进行转换（XML无法更改）。

我正在使用一组带有for-each循环的键来对数据进行分组，这对我的第一组和第二组很有效，但我的第三组不是迭代的。节点集是正确的，有3个节点可以循环，但它只是在第一次运行后停止并进入父循环的下一次迭代。

在下面的示例中，"options"模板应运行3次，因为$sec-rows变量有3个节点对应于3个xml记录。它不是。

任何帮助都会非常感激！

从最后一个（{3}}

中删除 Muenchian分组 
xsl:for-each

并输出所有三个值作为选项：

<xsl:variable name="sec-rows" select="key('row-by-day', concat(section_id, '|', question_obj))" />
<xsl:for-each select="$sec-rows">            <!-- removed key(..) -->
    <xsl:call-template name="options"/>
</xsl:for-each>

猜猜这就是你想要的。
