Exception converting json back to xml

I need to use this module for a project to do some processing on XML --> JSON --> XML.

Checked out the code today and apply it on the xml from here: https://raw.githubusercontent.com/GovReady/govready/master/prototypes/ssg-rhel6-oval.xml

Got error

/Users/jdole/learn/node/node_modules/fast-xml-parser/src/xmlstr2xmlnode.js:48
    xmlData = xmlData.replace(/<!--[\s\S]*?-->/g, "");//Remove  comments
                      ^

TypeError: xmlData.replace is not a function

The code snippet is adopted from your example.

var parser = require('fast-xml-parser');
var he = require('he');
var fs=require("fs");

var options = {
    attributeNamePrefix : "@_",
    attrNodeName: "attr", //default is 'false'
    textNodeName : "#text",
    ignoreAttributes : false,
    ignoreNameSpace : false,
    allowBooleanAttributes : false,
    parseNodeValue : true,
    parseAttributeValue : false,
    trimValues: true,
    cdataTagName: "__cdata", //default is 'false'
    cdataPositionChar: "\\c",
    localeRange: "", //To support non english character in tag/attribute values.
    parseTrueNumberOnly: false,
    attrValueProcessor: a => he.decode(a, {isAttributeValue: true}),//default is a=>a
    tagValueProcessor : a => he.decode(a) //default is a=>a
};
xml=fs.readFileSync("ssg-rhel6-oval.xml", "utf8");

var result1;
var jsonObj = parser.parse(xml,options);
console.log(parser.parse(jsonObj))

Is this a bug in this module?

[Treverix]

The problem he faced was, like mine, that he didn’t convert the file contents to a string.

This causes the error:

xml=fs.readFileSync("ssg-rhel6-oval.xml", "utf8");

And this works:

xml=fs.readFileSync("ssg-rhel6-oval.xml", "utf8").toString();

I’ve just tested your file. everything looks fine to me.

const fs = require("fs");
const path = require("path");
const fileNamePath = path.join(__dirname, "./ssg-rhel6-oval.xml");

const xmlData = fs.readFileSync(fileNamePath).toString();

const jsObj = parser.parse(xmlData);
const j2xParser = new parser.j2xParser();
const result = j2xParser.parse(jsObj);
