Converting XML to CSV using XSLT Formatting Issue - csv

Question

I have the following XML
<Data>
<Employee>
<Name>
<FirstName>John</FirstName>
<LastName>Snow</LastName>
</Name>
<DOB>1990-01-01</DOB>
<Passport>
<Country>United Kingdom</Country>
<ID>12345678</ID>
</Passport>
<Passport>
<Country>United States of America</Country>
<ID>789101112</ID>
</Passport>
</Employee>
</Data>
And I am converting it as seen below:
<xsl:for-each select="Data/Employee">
<xsl:value-of select="Name/FirstName"/>
<xsl:text>,</xsl:text>
<xsl:value-of select="Name/LastName"/>
<xsl:text>,</xsl:text>
<xsl:for-each select="Passport">
<xsl:value-of select="Country"/>
<xsl:text>,</xsl:text>
<xsl:value-of select="ID"/>
<xsl:text>
</xsl:text>
</xsl:for-each>
<xsl:text>,</xsl:text>
<xsl:value-of select="DOB"/>
</xsl:for-each>
The output I am getting is:
John,Snow,United Kingdom,12345678
United States of America,789101112
,1990-01-01
But I require the passport information to be populated below each other and then DOB to be shown on the top line as seen below:
John,Snow,United Kingdom,12345678,1990-01-01
,,United States of America,789101112
Any help would be appreciated

Perhaps like this:
XSLT 2.0
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >
<xsl:output method="text" encoding="UTF-8"/>
<xsl:template match="/Data">
<xsl:for-each select="Employee">
<xsl:for-each select="Passport">
<xsl:choose>
<xsl:when test="position()=1">
<xsl:value-of select="../Name/(FirstName, LastName), Country,ID, ../DOB" separator=","/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="'', '', Country,ID, ''" separator=","/>
</xsl:otherwise>
</xsl:choose>
<xsl:text>
</xsl:text>
</xsl:for-each>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Note that I have added a trailing comma in the place of the "missing" DOB.
