How to retrofit an XSL template to transform xml2Json?

Question

JSON

Hello! I have an xml to json conversion template.
There is 1 problem: you need to modernize it so that all xml tags during the "pass" to json become lowercase (only tag names, the values ​​themselves must be in the original).
Link to xsl
I don't understand xsl well. If someone is in the subject, save.
For example like this:
XML:

<Widget>
<VALUE>Dfdfdf</VALUE>
</wiDget>

Json:
"widget" : {"value" : "Dfdfdf" }
As you can see from the example, the tag names have changed to lowercase, but the case has been preserved in the value.

Answer 1

Add to the beginning of the template:

<xsl:variable name="smallcase" select="'abcdefghijklmnopqrstuvwxyz'" />
<xsl:variable name="uppercase" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'" />

In the places where the node name is received, add a call to the translate() function:

...
<xsl:variable name="nName" select="translate(name(.), $uppercase, $smallcase)"/>
...

XSL 2.0 provides the lower-case() function for this purpose.
