XSLT to convert XML to JSON Array - arrays

Question

I am currently using SAP CPI to achieve this conversion. I have tried the regular XML to JSON converter available but was not able to achieve this requirement. I then set out to try and see if XSLT can help.
I am trying to convert the following XML payload:
<root>
<ClientID>1</ClientID>
<PackageID>650</PackageID>
<SBUID>2187</SBUID>

As you can see, there is an array created for every part of the data. How can I achieve this with XSLT?
Whatever code i have tried with so far, the converted JSON has not had any arrays barring cases where there are multiple records under a root.
I have tried variations of the following code:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ns0="http://use your namespace">
<xsl:output method="text"/>
<xsl:template match="/ns0:Account_Resp">{
<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="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 `enter code here`match="#*">"<xsl:value-of select="name()"/>" : "<xsl:value-of select="."/>",
</xsl:template>
</xsl:stylesheet>
And received the following output - in which you can see that for single payloads, an array is not getting created:

Really need some help on this.
Thanks

Answer 1

In order to determine which XML elements can occur with cardinality 0..*, you look only at the actual cardinality in the payload by testing whether count(*[name()=$childName]) > 1. By this, you miss the fact that the <EducationList> is allowed to contain more than one <Education> (even if it contains only one in this particular payload instance).
A clean solution would require you to look at the XML schema (in the WSDL document, probably). But in this case, the following heuristics might suffice: If an element name ends with List, it contains children with cardinality 0..*. Therefore, replace the test count(*[name()=$childName]) > 1 with
substring(name(), string-length(name()) - 3, 4) = 'List'

Answer 2

With the YAML processor mikefarah/yq, you can convert XML to JSON and make some custom adoptions to the conversion:
yq --input-format xml --output-format json '
with(.root;
.AddressHistory.Address |= select(type == "!!map") |= [.] |
.EducationList.Education |= select(type == "!!map") |= [.] |
.EmploymentList.Employment |= select(type == "!!map") |= [.] |
.AddressReferencesList.ListofReferences |= select(type == "!!map") |= [.] |
.PVWDetails.AddressList.Address |= select(type == "!!map") |= [.]
)
' input.xml
For given paths the update operator |= wraps an object (select(type == "!!map")) into an array ([.]).
Add all elements that should be an array to the code.
With kislyuk/xq, you can solve it this way:
ARRAY_PATHS='
[
"root.AddressHistory.Address",
"root.EducationList.Education",
"root.EmploymentList.Employment",
"root.AddressReferencesList.ListofReferences",
"root.PVWDetails.AddressList.Address"
]
'
xq --argjson paths "$ARRAY_PATHS" '
. as $input
| reduce ($paths
| map(split(".") # split given paths by "."
| . as $p
| select($input | getpath($p) | type == "object")))[] # process only objects at the given paths (ignore arrays)
as $path
(.; setpath($path; [getpath($path)])) # wrap objects at the given paths in an array
' input.xml
All given paths are checked if the value is an object: select($input | getpath($p) | type == "object").
Objects are wrapped into an array setpath($path; [getpath($path)]).
This solution is more generic and failsafe, if a given path is missing in the input.
Output (both versions)

Answer 3

The standard xml-to-json XSLT 3.0 function can meet your requirement. The complexity lies in establishing the transform rules for when to use JSON maps and arrays.
I inferred the transform rules from the supplied input XML and output JSON. These rules may need adjustment to cover cases not tested by your sample. Here's the main xsl:template instruction:
<xsl:template match="*[*]" mode="outer">
<xsl:param name="key" as="xs:string?"/>
<xsl:variable name="distinctChildNames" as="xs:string*" select="*!name() => distinct-values()"/>
<xsl:choose>
<xsl:when test="count($distinctChildNames) gt 1 and exists($key)">
<array>
<xsl:sequence select="fn:keyAttribute(name())"/>
<map>
<xsl:apply-templates select="*" mode="outer">
<xsl:with-param name="key" select="name()"/>
</xsl:apply-templates>
</map>
</array>
</xsl:when>
<xsl:when test="count(*) gt 1 and count($distinctChildNames) eq 1">
<map>
<xsl:sequence select="fn:keyAttribute(name())"/>
<array key="{name(*[1])}">
<xsl:for-each select="*">
<map>
<xsl:apply-templates select="*" mode="outer"/>
</map>
</xsl:for-each>
</array>
</map>
</xsl:when>
<xsl:otherwise>
<map>
<xsl:sequence select="fn:keyAttribute(name())"/>
<xsl:apply-templates select="*" mode="outer">
<xsl:with-param name="key" select="name()"/>
</xsl:apply-templates>
</map>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
The JSON output:

There are minor differences in the result:
The '/' character is escaped to \/ in the JSON output
JSON properties transformed from empty XML elements: the XSLT here always keeps the property and sets the value to an empty string
