XML to JSON (Webhooks slack) - json

Question

I would like to convert an XML to JSON using xslt transformation.The purpose is to POST into my slack channel using Incoming Webhooks.
XML File :
<?xml version="1.0" encoding="UTF-8" ?>
<Asset version="1.0">
<Process>
<Date>2017-01-24 14:47:35</Date>
<Status>Success</Status
> <Profile>TEST</Profile>
<Station>DESKTOP</Station>
<User>Système</User>
<Application>APP</Application>
</Process>
<Source>
</Source>
<Target>
<Name>Hello.mp4</Name>
</Target>
</Asset>
I tried this :
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xsl:output method="txt" omit-xml-declaration="yes" encoding="UTF-8"/>
<xsl:template match="/">
{
"text":"<xsl:value-of select="Asset/Process/Profile"/>",
"text":"<xsl:value-of select="Asset/Process/Date"/>",
"text":"<xsl:value-of select="Asset/Target/Name"/>",
"text":"<xsl:value-of select="Asset/Process/Status"/>",
}
</xsl:template>
</xsl:stylesheet>
But i've got this error : 500 - missing_text_or_fallback_or_attachments
Do you have any idea ?

Here is the XSLT which produces the desired JSON String:
XSLT 2.0
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xsl:output method="text" omit-xml-declaration="yes" encoding="UTF-8"/>
<xsl:template match="/">
<xsl:text>{ "text": "</xsl:text>
<xsl:for-each select="Asset/Process/*">
<xsl:choose>
<xsl:when test="position()=1">
<xsl:value-of select="concat(local-name(),': ',.,'\n')"/>
</xsl:when>
<xsl:when test="position()=last()">
<xsl:value-of select="concat(' ',local-name(),': ',.)"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="concat(' ',local-name(),': ',.,'\n')"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
<xsl:text>"}</xsl:text>
</xsl:template>
</xsl:stylesheet>
