XSLT split address on line break - xslt

Question

I have one XML with an address like this:
<ADDRESS>SHIPPING ADDRESS 1
SHIPPING ADDRESS 2
SHIPPING ADDRESS 3</ADDRESS>
and I need to convert it to:
<ADDRESS1>SHIPPING ADDRESS 1</ADDRESS1>
<ADDRESS2>SHIPPING ADDRESS 2</ADDRESS2>
(ignore third line).
NOTE: I am using XSLT 1.0

Answer 1

If you only want the first two lines, you could do:
<xsl:template match="ADDRESS">
<ADDRESS1>
<xsl:value-of select="substring-before(., '
')" />
</ADDRESS1>
<ADDRESS2>
<xsl:value-of select="substring-before(substring-after(., '
'), '
')" />
</ADDRESS2>
</xsl:template>
This assumes there are at least three lines. Otherwise it gets a bit more complicated. For example, you could use:
<xsl:template match="ADDRESS">
<xsl:variable name="address" select="concat(., '
')" />
<ADDRESS1>
<xsl:value-of select="substring-before($address, '
')" />
</ADDRESS1>
<ADDRESS2>
<xsl:value-of select="substring-before(substring-after($address, '
'), '
')" />
</ADDRESS2>
</xsl:template>
to create two address lines no matter how many lines the source address has.

Answer 2

Here's another answer that works for any number of lines:
<xsl:template match="ADDRESS">
<xsl:call-template name="splitAddress">
<xsl:with-param name="string" select="."/>
</xsl:call-template>
</xsl:template>
<xsl:template name="splitAddress">
<xsl:param name="string"/>
<xsl:param name="AddrNo" select="1"/>
<xsl:choose>
<xsl:when test="$AddrNo = 2">
<xsl:element name="ADDRESS{$AddrNo}">
<xsl:value-of select="substring-before($string, '
')"/>
</xsl:element>
</xsl:when>
<xsl:when test="contains($string, '
')">
<xsl:element name="ADDRESS{$AddrNo}">
<xsl:value-of select="substring-before($string, '
')"/>
</xsl:element>
<xsl:call-template name="splitAddress">
<xsl:with-param name="string" select="substring-after($string, '
')"/>
<xsl:with-param name="AddrNo" select="$AddrNo + 1"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:element name="ADDRESS{$AddrNo}">
<xsl:value-of select="$string"/>
</xsl:element>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
--Edit--
I missed the requirement to stop after the second address line. I've inserted the xsl:when above to end the processing as required: the condition here can be edited as required.
