How to response XML with node.js express?

Question

I want to response this using node.js and express:

<set id="1" state="0" name="wd"/>

I tried:

xml = require('xml');

res.set('Content-Type', 'text/xml');
res.send(xml('<set id="1" state="0" name="wd"/>'));

But in Wireshark i see that my response looks:

&lt;set id=&quot;1&quot; state=&quot;0&quot; name=&quot;wd&quot;/&gt;

How to send my xml correctly?

xml package converts JS objects to xml (and you are passing a stringified xml). Not what you need. You need to parse the string containing xml to get actual xml data using libxmljs.

I would try this:

const libxmljs = require("libxmljs");


let stringifiedXml = '<set id="1" state="0" name="wd"/>';
let xmlDoc = libxmljs.parseXml(stringifiedXml);

res.set('Content-Type', 'text/xml');
res.send(xmlDoc);

When i tried to console.log(xmlDoc) i got Document{errors:[]}. What can i miss?

I think that console.log(xmlDoc) doesnt support xml data. Maybe you can try console.dirxml(xmlDoc) nodejs.org/api/console.html#console_console_dirxml_data

Try removing xml() function. If you set Content-type, the server would send response as xml.

In ExpressJs Simply add the content-type and send a valid XML document as the xmlContent

response.type('application/xml')
response.send(xmlContent)
