Output multiple elements as a JSON array in XSLT - json

Question

I have an XSL Code as shown below.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes" omit-xml-declaration="yes" />
<xsl:variable name="inlineAddressArray">
<addrline>Home1</addrline>
<addrline>Home2</addrline>
<addrline>Home3</addrline>
</xsl:variable>
<xsl:variable xmlns:exsl="http://exslt.org/common" name="data" select="exsl:node-set($inlineAddreddArray)" />
<addressLines>
<xsl:value-of select="$data/addrline" />
</addressLines>
</xsl:stylesheet>
My expected JSON output should be:
"addressLines":"[Home1,Home2,Home3]"
Output that I'm getting
"addressLines": "Home1Home2Home3"
Basically it is just concatenating every element as a single element.
But, I should get three elements separately as shown above.
Can anyone please help me on this? Don't mind if it's a silly query. I'm very new to XSLT :)

No need for Newtonsoft.Json.JsonConvert.SerializeXmlNode() .
Given this xml:
<inlineAddressArray>
<addrline>Home1</addrline>
<addrline>Home2</addrline>
<addrline>Home3</addrline>
</inlineAddressArray>
Using this xslt 2.0:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:output method="text" encoding="UTF-8" />
<xsl:template match="inlineAddressArray">
<xsl:text>"addressLines":"[</xsl:text>
<xsl:value-of select="addrline" separator=","/>
<xsl:text>]"</xsl:text>
</xsl:template>
</xsl:stylesheet>
or using xslt 1.0
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text" encoding="UTF-8" />
<xsl:template match="inlineAddressArray">
<xsl:text>"addressLines":"[</xsl:text>
<xsl:apply-templates select="addrline"/>
<xsl:text>]"</xsl:text>
</xsl:template>
<xsl:template match="addrline">
<xsl:value-of select="."/>
<xsl:if test="not(position()=last())">
<xsl:text>,</xsl:text>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
results in this :
"addressLines":"[Home1,Home2,Home3]"
UPDATE
if you also want to deal with empty addrline like i.e.
<inlineAddressArray>
<addrline>Home1</addrline>
<addrline>Home2</addrline>
<addrline></addrline>
</inlineAddressArray>
Your xslt 1.0 could look like this:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text" encoding="UTF-8" />
<xsl:template match="inlineAddressArray">
<xsl:text>"addressLines":"[</xsl:text>
<xsl:apply-templates select="addrline"/>
<xsl:text>]"</xsl:text>
</xsl:template>
<xsl:template match="addrline">
<xsl:value-of select="."/>
<xsl:if test=" following-sibling::addrline[(normalize-space(.))]">
<xsl:text>,</xsl:text>
</xsl:if>
</xsl:template>
<xsl:template match="addrline[not(normalize-space(.))]"/>
</xsl:stylesheet>
