I want to convert:
{
Employer: {
Name: 'Sample',
Age: 23
}
}
To:
<EMPLOYER NAME="Sample" AGE="23"></EMPLOYER>
Is this possible? Or if you can suggest an npm package I would greatly appreciate it.

That's a little bit tricky... how will that converter choose between creating new nodes or setting data as params? I don't think there is something generic for you.Nurio Fernandez– Nurio Fernandez2021-05-06 08:30:21 +00:00Commented May 6, 2021 at 8:30

Yes I am having a really hard time too. The big problem is it comes from a third party api so I have no other choice but to work with it. I think its a very old XML format.Ryan Garde– Ryan Garde2021-05-06 08:36:49 +00:00Commented May 6, 2021 at 8:36

I would google it a little bit before doing something by myself, but if there is no other way, I would use regexp and create a custom serializer/converter for that case.Nurio Fernandez– Nurio Fernandez2021-05-06 08:38:52 +00:00Commented May 6, 2021 at 8:38

Find XML nodes <element><\element>
You can use this regular expression to match the XML nodes
const regex = /['"]?(\w+)['"]?[ ]?:[ ]?{(.[^}]+)}/gms;
Regexp101 Debug link: https://regex101.com/r/71cphG/3
const findNodes = (source) => {
const regexNodes = /['"]?(\w+)['"]?[ ]?:[ ]?{(.[^}]+)}/gms;
let nodes = [];
while (m = regexNodes.exec(str)) {
let nodeName = m[1]
let nodeBody = m[2]
nodes.push({ name: nodeName, body: nodeBody });
}
return nodes;
}
Find XML node params age=20
You can match node params with a regular expression like this:
const regex = /\s+(\w+) ?: ?['"]?(.[^'^"\n]+)['"]?/gms;
Regexp101 Debug link: https://regex101.com/r/upMtcz/1
const generateNode = (nodeName, jsonBody) => {
const regexParams = /\s+(\w+) ?: ?['"]?(.[^'^"\n]+)['"]?/gms;
let result = `<${nodeName}`;
while (matches = regexParams.exec(jsonBody)) {
let param = `${matches[1]}=${matches[2]}`;
result += ` ${param}`;
}
result += `></${nodeName}>`
return result;
}
Print results
const findNodes = (source) => {
const regexNodes = /['"]?(\w+)['"]?[ ]?:[ ]?{(.[^}]+)}/gms;
let nodes = [];
while (m = regexNodes.exec(str)) {
let nodeName = m[1]
let nodeBody = m[2]
nodes.push({ name: nodeName, body: nodeBody });
}
return nodes;
}
const generateNode = (nodeName, jsonBody) => {
const regexParams = /\s+(\w+) ?: ?['"]?(.[^'^"\n]+)['"]?/gms;
let result = `<${nodeName}`;
while (matches = regexParams.exec(jsonBody)) {
let param = `${matches[1]}=${matches[2]}`;
result += ` ${param}`;
}
result += `></${nodeName}>`
return result;
}
const str = `{
"Employer" : {
Name: 'Sample',
Age: 23
},
Employer: {
Name: 'Sample',
Age: 23
},
Employer: {
Name: 'Sample',
Age: 23
}
}`;
findNodes(str)
.map(({ name, body }) => generateNode(name, body))
.forEach(element => console.log(element))1 Comment

I have added a few code examples for you, as I said before, I would google for a better approach if there is any.
