wish of those help I am trying to work with XML data from an https.request and display it to a web page in table format. I'm trying to follow this tutorial which describes what I would like to do very well: https://programmerblog.net/parse-xml-using-nodejs/ , if you want to get all css nodes, you can try this

code :

const transform = require('camaro')

const xml = `
<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<ns:listCssResponse xmlns:ns="http://www.cisco.com/AXL/API/11.0">
<return>
<css uuid="{E85C54E1-5737-7516-FFFC-14E97B1D0504}">
<description>description1</description>
<clause>something1</clause>
<name>name1</name>
</css>
<css uuid="{AFFC55A7-CD16-E250-09E8-9A12ABBE0C9E}">
<description>description2</description>
<clause>something2</clause>
<name>name2</name>
</css>
</return>
</ns:listCssResponse>
</soapenv:Body>
</soapenv:Envelope>
`

const json = transform(xml, {
    css: ['//css', {
        uuid: '@uuid',
        name: 'name',
        description: 'description',
        clause: 'clause'
    }]
})

console.log(json.css)

[ { clause: 'something1',
    description: 'description1',
    name: 'name1',
    uuid: '{E85C54E1-5737-7516-FFFC-14E97B1D0504}' },
  { clause: 'something2',
    description: 'description2',
    name: 'name2',
    uuid: '{AFFC55A7-CD16-E250-09E8-9A12ABBE0C9E}' } ]

Any of those help Managed to enable the HTTP persistency which got the issue fixed. Simply I used the www-request node (an alternative enhanced node similar to the core http-request node) and enabled the forever feature on the www-request.

seems to work fine Managed to do it, posting the solution if anyone is interested.
I ended up having to monkey patch the write method as well:

code :

const http = require('http');

const oldHttpRequest = http.request;

http.request = (options, callback) => {
    const requestBodyChunks = [];
    const newCallback = (res) => {
        // Do logging logic here
        console.log('Request body:', requestBodyChunks.join())

        return callback(res);
    }

    const clientRequest = oldHttpRequest(options, newCallback);
    const oldWrite = clientRequest.write.bind(clientRequest);

    clientRequest.write = (data: any) => {
        requestBodyChunks.push(data.toString());
        return oldWrite(data);
    };

    return clientRequest;
};
