我们如何在XSLT中使用for循环？
我有这个要求，我想将下面显示的xml转换为逗号分隔文件。 CSV文件中的行数将等于员工报告条目的COBRA_Records_within_Range个节点数。除COBRA_Records_within_Range个节点的子元素值外，3行中的所有值都相同。我能够创建3行但无法检索COBRA_Records_within_Range的子元素的值。我想在特定节点的计数上运行for循环，然后根据迭代检索其子元素。在下面的示例中，有3个COBRA_Records_within_Range nodes。所以循环应该运行count（COBRA_Records_within_Range）`然后在每次迭代中我需要来自其子节点的值。例如，如果是第二次迭代，那么Eligibility_Reason应该在CSV输出中显示为“受抚养子女 - 计划规则下失去受抚养子女身份”。
有人可以帮帮我吗？
<?xml version="1.0" encoding="UTF-8"?>
<root>
<wd:Report_Entry xmlns:wd="urn:com.workday/bsvc">
<wd:Employee_ID>111111</wd:Employee_ID>
<wd:Worker>John Smith</wd:Worker>
<wd:Employee_Last_Name>Smith</wd:Employee_Last_Name>
<wd:Employee_First_Name>John</wd:Employee_First_Name>
<wd:COBRA_Records_within_Range>
<wd:Qualifying_Event_Date>2015-10-04</wd:Qualifying_Event_Date>
<wd:Eligibility_Reason>Dependent Children - Loss of dependent child status under the
plan rules</wd:Eligibility_Reason>
<wd:Benefit_Plan1>Dental-US - Delta Dental PPO BREG</wd:Benefit_Plan1>
</wd:COBRA_Records_within_Range>
<wd:COBRA_Records_within_Range>
<wd:Qualifying_Event_Date>2015-10-05</wd:Qualifying_Event_Date>
<wd:Eligibility_Reason>Dependent Children - Loss of dependent child status under the
plan rules</wd:Eligibility_Reason>
<wd:Benefit_Plan1>Healthcare FSA - Tri-Ad FSA Residential US</wd:Benefit_Plan1>
</wd:COBRA_Records_within_Range>
<wd:COBRA_Records_within_Range>
<wd:Qualifying_Event_Date>2015-10-05</wd:Qualifying_Event_Date>
<wd:Eligibility_Reason>Spouse - Divorce or legal separation of the covered
employee</wd:Eligibility_Reason>
<wd:Test>0</wd:Test>
<wd:Benefit_Plan1>Medical/Vision-US - Empire Blue Cross & Blue Shield
EPO</wd:Benefit_Plan1>
</wd:COBRA_Records_within_Range>
</wd:Report_Entry>
</root>
这是预期的输出 -
111111, John Smith, Smith, John, 2015-10-04, Dependent Children - Loss of dependent child status under the plan rules, Dental-US - Delta Dental PPO BREG
111111, John Smith, Smith, John, 2015-10-05, Dependent Children - Loss of dependent child status under the plan rules, Healthcare FSA - Tri-Ad FSA Residential US
111111, John Smith, Smith, John, 2015-10-05, Spouse - Divorce or legal separation of the covered employee, Medical/Vision-US - Empire Blue Cross & Blue Shield EPO
这是我创建的XSLT -

我在您尝试的XSLT中找不到任何押韵或理由。预期结果可以通过以下方式非常简单地实现：
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:wd="urn:com.workday/bsvc">
<xsl:output method="text" encoding="UTF-8"/>
<xsl:strip-space elements="*"/>
<xsl:template match="wd:Report_Entry">
<xsl:variable name="common">
<xsl:value-of select="wd:Employee_ID" />
<xsl:text>, </xsl:text>
<xsl:value-of select="wd:Worker" />
<xsl:text>, </xsl:text>
<xsl:value-of select="wd:Employee_Last_Name" />
<xsl:text>, </xsl:text>
<xsl:value-of select="wd:Employee_First_Name" />
<xsl:text>, </xsl:text>
</xsl:variable>
<xsl:for-each select="wd:COBRA_Records_within_Range">
<xsl:copy-of select="$common"/>
<xsl:value-of select="wd:Qualifying_Event_Date" />
<xsl:text>, </xsl:text>
<xsl:value-of select="wd:Eligibility_Reason" />
<xsl:text>, </xsl:text>
<xsl:value-of select="wd:Benefit_Plan1" />
<xsl:text> </xsl:text>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

在wd:COBRA_Records_within_Range元素的谓词中，您指定的是position()，但这并未提供xsl:for-each中序列的当前值。 position()是上下文节点的位置。
您只想过滤那些position()等于您xsl:for-each中当前号码的人。
为此，请在模板中添加另一个参数，并在调用时传递当前值：
在下面的示例中，我创建了一个名为rangeIndex的参数，并使用了简写谓词[$rangeIndex]，但也可以使用[position() = $rangeIndex]：

这是一个更简单，更简洁的解决方案， 完全不使用<xsl:for-each>：
<强>予。 XSLT 2.0
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:wd="urn:com.workday/bsvc">

<xsl:strip-space elements="*"/>
<xsl:variable name="vHeader"
select="string-join(/*/*/*[not(self::wd:COBRA_Records_within_Range)], ', ')"/>
<xsl:template match="wd:COBRA_Records_within_Range">
<xsl:value-of select="string-join(($vHeader, *), ', '), '
'"/>
</xsl:template>
<xsl:template match="text()"/>
