problems to convert single xml element to Json Array using XSLT
Question
I am using below generic xslt to convert xml into json, but few values are missing under first array attributes. Expectation is to use make ns1:Value as JSON array even if we get single xml element Here I have mentioned sample xml and json messages. XSLT code:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:template match="/">{
<xsl:apply-templates select="*"/>}
</xsl:template>
<!-- Object or Element Property-->
<xsl:template match="*">
"<xsl:value-of select="name()"/>" : <xsl:call-template name="Properties"/>
</xsl:template>
<!-- Array Element -->
<xsl:template match="*" mode="ArrayElement">
<xsl:call-template name="Properties"/>
</xsl:template>
<!-- Object Properties -->
<xsl:template name="Properties">
<xsl:variable name="childName" select="name(*[1])"/>
<xsl:choose>
<xsl:when test="not(*|@*)">"<xsl:value-of select="."/>"</xsl:when>
<xsl:when test="$childName = 'ns1:Value' or count(*[name()=$childName]) > 1">{ "<xsl:value-of select="$childName"/>" :[<xsl:apply-templates select="*" mode="ArrayElement"/>] }</xsl:when>
<xsl:otherwise>{
<xsl:apply-templates select="@*"/>
<xsl:apply-templates select="*"/>
}</xsl:otherwise>
</xsl:choose>
<xsl:if test="following-sibling::*">,</xsl:if>
</xsl:template>
<!-- Attribute Property -->
<xsl:template match="@*">"<xsl:value-of select="name()"/>" : "<xsl:value-of select="."/>",
</xsl:template>
</xsl:stylesheet>
Sample XML:
<?xml version="1.0" encoding="UTF-8"?>

EDIT
Some years ago I made a xml2json with xslt 1.0. This handles also escaping specials json-chars and other bonuses.
I adjusted it a little to your needs. Enjoy:
