[xsl] xsl:for-each in Corresp Tag

["Byomokesh Sahoo sahoo.byomokesh@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hi,

I am facing difficulty to get required output in different structure of
<corres>. Find the below three types of tagging structure.

Not getting exact output if apply <xsl:for-each> on below three type of
scenario.

XML

<corresp><label>Correspondence to</label> Anne Marie Darling, <institution
content-type="department">Department of Epidemiology</institution>,
<institution>Boston University</institution>, <addr-line
content-type="street">715 Albany Street</addr-line>,
<country>USA</country>; <email>amdarlin@xxxxxx</email></corresp>

<corresp><label>Correspondence to</label> Anne Marie Darling, <institution
content-type="department">Department of Epidemiology</institution>,
<addr-line content-type="postal-code">02118</addr-line>,
<country>USA</country>; </corresp>

<corresp>Joanne Lawrence, Association of British Neurologists, Ormond
House, 27 Boswell Street, London WC1N 3JZ, UK; <email>
joanne.lawrence@xxxxxxxxxx</email></corresp>

My XSLT
<xsl:template match="corresp">
<xsl:element name="corresp">
<xsl:for-each select="label">
<xsl:element name="x">
<xsl:value-of select="."/>
</xsl:element>
<xsl:text>, </xsl:text>
</xsl:for-each>
<institution>
<xsl:for-each select="institution">
<xsl:choose>
<xsl:when test="@content-type='department'">

<xsl:element name="department">
<xsl:apply-templates select="node()" mode="copy-no-namespaces"/>
</xsl:element>
<xsl:text>, </xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:element name="institution-name">
<xsl:value-of select="."/>
</xsl:element>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</institution>
<xsl:text>, </xsl:text>

<xsl:for-each select="addr-line">
<xsl:choose>
<xsl:when test="@content-type='street'">
<xsl:element name="street">

</xsl:element>
<xsl:text>, </xsl:text>
</xsl:when>
</xsl:choose>
</xsl:for-each>
<xsl:for-each select="country">
<xsl:element name="country">
<xsl:value-of select="."/>

<xsl:text>; </xsl:text>
</xsl:for-each>
<xsl:for-each select="email">
<xsl:element name="email">

</xsl:element>
</xsl:for-each>
</xsl:element>
</xsl:template>
