xml-to-json-promise is based on the xml2js package (which itself is based on sax-js). I use xml2js and promisify it myself, but the trick is the options.tagNameProcessors. Read about them in the docs
Use it like this:
const prefixMatch = new RegExp(/(?!xmlns)^.*:/)
function stripPrefix(str) {
return str.replace(prefixMatch, '');
}
convert.xmlDataToJSON(xml, {
tagNameProcessors: [stripPrefix]
// other options too
})
This is included in xml2js package and could be required like so:
const {stripPrefix} = require('xml2js/lib/processors')
Anyway, there ya go! Tag names are processed to rename the key (removing any prior prefix).
