Re: [xsl] problem with json-to-xml()

["Christophe Marchand cmarchand@xxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

XPath map functions are in a different namespace than other standard 
functions. See https://www.w3.org/TR/xpath-functions-31/#map-functions

So, your XPath expression become : <xsl:value-of 
select="json-to-xml(unparsed-text('json'))/map:map/map:string[@key='id']"/>

Best,
Christophe
