XML to JSON, preserve whitespace option

[cokosharp]

Hello, I couldn't find any option to preserve whitespace for doc.end or convert functions, so I thought I'd try here.

In my xmlString, there's a property containing only whitespace values.
XML:
<ValueWithBlankSpaces> </ValueWithBlankSpaces>

When I convert it to JSON using doc.end() or convert(), the value becomes an empty object.
const doc = create(xmlString);
const jsonString = doc.end({ format: "json" });

JSON:
"ValueWithBlankSpaces": {}

Is there an option I can use to preserve the whitespace(s)?
