问题
I have the following xml file. I need to be able to generate a csv file based on below. However the catch is if its the same effective moment and there are multiple sequence attributes it should generate just one line of output, however if the effective moment (just date part) is different then it should generate a line each based on the effective moment. I have trying to play with xslt but have been struggling so far. Any help provided will be appreciated.

Assuming that:
- you can use XSLT 2.0,
- the output should contain separate row for each
Effective_Moment(date part), for each employee,
you can do the task the following way:
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:transform version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:peci="urn:com.w/peci" xpath-default-namespace="urn:com.w/peci">
<xsl:output method="text" encoding="UTF-8"/>
<xsl:template match="Workers_Effective_Stack">
<xsl:for-each-group select="Worker/Effective_Change" group-by=
"concat(../Worker_Summary/Employee_ID, substring(Effective_Moment,1,10))">
<xsl:value-of select="../Worker_Summary/Employee_ID"/>
<xsl:text>,</xsl:text>
<xsl:value-of select="substring(Effective_Moment, 1, 10)"/>
<xsl:text>,</xsl:text>
<xsl:value-of select="Worker_Status/Status"/>
<xsl:text>
</xsl:text>
</xsl:for-each-group>
</xsl:template>
</xsl:transform>
Caution: Your source XML has one unbalanced peci:Worker opening tag, I deleted them.
Note: It is possible to perform grouping solely by the effective date, but I think is not what you want. If your input contained a number of effective changes for different employees, but on the same effective date, then the output would have contained only one record from this group. This is why I performed grouping using a composite key, including also the employee ID.
