Match node in JSON input - xslt

Question

I have the following code, which I am using to transform a JSON file to another JSON.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:exsl="http://exslt.org/common" xmlns:fcn="http://www.re.com/2018/local-functions" xmlns:fn="http://www.w3.org/2005/xpath-functions" xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs fn fcn exsl" version="3.0">
<xsl:param as="xs:string" name="json">[{
"results": [
{
"id": "5b33c2e8-8ab2-4314-82bf-e41a007c076f",
"profileId": "0f53bfe5-4ef3-4424-9ad2-ad8181007e22"
}
],
"_embedded": {
},
"paging": {
"pageNumber": 1,
"pageSize": 10,
"totalCount": 4
}
}]</xsl:param>
<xsl:output indent="yes" method="text" />
<xsl:template match="/" name="xsl:initial-template">
<xsl:variable name="input-as-xml" select="json-to-xml($json)" />
<xsl:variable name="transformed-xml">
<array xmlns="http://www.w3.org/2005/xpath-functions">
<xsl:for-each select="fn:array[#key = 'results']/*">
<map>
<xsl:if test="*[#key = 'id'] != ''">
<string key="id">
<xsl:value-of select="fn:string[#key = 'id']" />
</string>
</xsl:if>
</map>
</xsl:for-each>
</array>
</xsl:variable>
<xsl:value-of select="xml-to-json($transformed-xml, map {'indent': true()})" />
</xsl:template>
</xsl:stylesheet>
I am trying to match the results object, but when I apply the stylesheet, I am getting an empty JSON output.
Some help with matching the results object correctly would be appreciated.
The input-as-xml:
<?xml version="1.0" encoding="UTF-8"?>
<array xmlns="http://www.w3.org/2005/xpath-functions">
<map>
<array key="results">
<map>
<string key="id">5b33c2e8-8ab2-4314-82bf-e41a007c076f</string>
<string key="profileId">0f53bfe5-4ef3-4424-9ad2-ad8181007e22</string>
</map>
</array>
<map key="_embedded"/>
<map key="paging">
<number key="pageNumber">1</number>
<number key="pageSize">10</number>
<number key="totalCount">4</number>
</map>
</map>
</array>

Answer 1

For starters, I think the xsl:for-each should be something like <xsl:for-each select="$input-as-xml/fn:array[#key = 'results']/*">, so you're selecting within the right context.
But I don't think that's quite enough: The XML that comes from the conversion will contain an <fn:array> whose first child will be an <fn:map> which will have an entry of the form <fn:array key="results">, so you need to select deeper into the structure.
It's probably a good idea to print out the value of $input-as-xml (in indented form) for ease of diagnostics.
