I am trying to convert given json data from one form to another using XSLT 3.0. I am using json-to-xml and xml-to-json functions provides by XSLT 3.0 to convert data from.to json to/from xml .
I am having below json data.
{
"serviceCode":"ATOM",
"action":"SCHEDULE",
"customerId":864,
"instance":"DWHPRD",
"serviceParameters":[
{
"parameterName":"team",
"parameterValue":"EBS"
}
],
"arguments":[
{
"argumentKey":"rfc",
"argumentValue":"3-BW9R3UA"
},
{
"argumentKey":"sid",
"argumentValue":"DWHPRD"
},
{
"argumentKey":"schedule_at",
"argumentValue":"2023-07-02 15:10:00"
},
{
"argumentKey":"update_rfc",
"argumentValue":false
},
{
"argumentKey":"dynamic_args",
"argumentValue":[
{
"argumentKey":"task_name",
"argumentValue":"Exa CPU Bursting Task"
},
{
"argumentKey":"arg_name",
"argumentValue":"$CPU Count",
"parent":{
"argumentKey":"task_name",
"argumentValue":"Exa CPU Bursting Task"
}
},
{
"argumentKey":"arg_value",
"argumentValue":"2",
"parent":{
"argumentKey":"task_name",
"argumentValue":"Exa CPU Bursting Task"
}
},
{
"argumentKey":"task_name",
"argumentValue":"Exa CPU Bursting DB Task"
},
{
"argumentKey":"arg_name",
"argumentValue":"$Target DB CPU Count",
"parent":{
"argumentKey":"task_name",
"argumentValue":"Exa CPU Bursting DB Task"
}
},
{
"argumentKey":"arg_value",
"argumentValue":"3",
"parent":{
"argumentKey":"task_name",
"argumentValue":"Exa CPU Bursting DB Task"
}
}
]
}
]
}
I am trying to convert it to below form using XSLT 3.0
{
"rfc":"3-BW9R3UA",
"sid":"DWHPRD",
"job_id":972,
"schedule_at":"2023-07-02 15:10:00",
"update_rfc":false,
"dynamic_args":[
{
"task_name":"Exa CPU Bursting Task",
"arg_name":"$CPU Count",
"arg_value":"2"
},
{
"task_name":"Exa CPU Bursting DB Task",
"arg_name":"$Target DB CPU Count",
"arg_value":"3"
}
]
}
I came up with below XSLT (incomplete as i am getting error at level 1)
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
version="3.0"
xmlns="http://www.w3.org/2005/xpath-functions"
xpath-default-namespace="http://www.w3.org/2005/xpath-functions"
expand-text="yes">
<xsl:param name="jsonText"/>
<xsl:output method="text"/>
<xsl:template name="init">
<xsl:variable name="input-as-xml" select="json-to-xml($jsonText)"/>
<xsl:variable name="transformed-xml">
<map>
<xsl:for-each select="$input-as-xml//array[@key='arguments']//map">
<string key="{string[@key='argumentKey']}"> <xsl:value-of
select="string[@key='argumentValue']"/></string>
</xsl:for-each>
</map>
</xsl:variable>
<xsl:value-of select="xml-to-json($transformed-xml)"/>
</xsl:template>
</xsl:stylesheet>
Can anyone help me on how i can get desired output json.
It seems you want to skip some stuff but group nested array contents:
<?xml version="1.0" encoding="utf-8"?>

exclude-result-prefixes="#all"
expand-text="yes">

I haven't understood where "job_id":972 comes from and when numbers should be numbers or strings in the output.
