Description

As per Changelog, ignoreNameSpace option in V3 is change to removeNSPrefix in V4. However, this option doesn't seem to work. This is one of the critical options because it changes the output JSON tagnames completely, for an input XML which has namespaces in tag names.

Input

<?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> <soapenv:Header/> <soapenv:Body><Data>Hello</Data></soapenv:Body></soapenv:Envelope>

Code

const { XMLParser } = require("fast-xml-parser");
const fastXmlParser = new XMLParser();
var xmlParserOptions = {
    attrPrefix: "",
    textNodeName: "text",
    ignoreTextNodeAttr: false,
    removeNSPrefix: true,
    textNodeConversion: false
};
var json = fastXmlParser.parse(xmlBody, xmlParserOptions);

Output

{"?xml":"","soapenv:Envelope":{"soapenv:Header":"","soapenv:Body":{ "Data": "Hello" }}}

expected data

{"?xml":"","Envelope":{"Header":"","Body":{ "Data": "Hello" }}}

@prithwirajbose options are supposed to be passed in constructor not the parsing method. Check https://solothought.com/tutorial/fast-xml-parser-4.2-features/ for a few example how the library is supposed to be used.
