Adding parent xml node to json using xslt version 1.0 - json

Question

I need to add parent xml to json content using xslt version 1.0. I have tried multiple ways to get this but no luck.
**Input Content:**
------------------
{
"EmployerRegistrationReq": {
"EmployerRegistrationReq": {
"EmployerRegistrationHeader": {
"CorporateID": "SIT0001",
"CorpReferenceNumber": 48499964
}
}
}
}
**Expected Output:**
--------------------
<Library>
{
"EmployerRegistrationReq": {
"EmployerRegistrationReq": {
"EmployerRegistrationHeader": {
"CorporateID": "SIT0001",
"CorpReferenceNumber": 48499964
}
}
}
}
</Library>
Can anyone help me here:

Answer 1

In XSLT 1.0, this will be simple textual manipulation. You won't be able to treat your JSON as a structured item, at least, not without some additional libraries.
If your only problem is to take a "string" value, here a string that can be a serialization of a JSON value, and to make it the text() node child of an element <Library> then the problem is simply one of passing your JSON String text as a parameter to an XSLT 1.0 transformation and then use this stylesheet:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:param name="jsonString" />
<xsl:template match="/" >
<Library><xsl:value-of select="$jsonString" /></Library>
</xsl:template>
</xsl:stylesheet>

You can use an external entity, I think:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE root [
<!ENTITY json SYSTEM "json-sample1.json">
]>
<root>&json;</root>
Caveat: use of DTDs/entities might be restricted/disabled these days due to security default settings.
