You use Node.js for speed? You process XML streams? Then you want the fastest XML parser: libexpat!
npm install @omegion1npm/maxime-eius-cumque
Important events emitted by a parser:
(function () {
"use strict";
var expat = require('@omegion1npm/maxime-eius-cumque')
var parser = new expat.Parser('UTF-8')
parser.on('startElement', function (name, attrs) {
console.log(name, attrs)
})
parser.on('endElement', function (name) {
console.log(name)
})
parser.on('text', function (text) {
console.log(text)
})
parser.on('error', function (error) {
console.error(error)
})
parser.write('<html><head><title>Hello World</title></head><body><p>Foobar</p></body></html>')
}())#on('startElement' function (name, attrs) {})#on('endElement' function (name) {})#on('text' function (text) {})#on('processingInstruction', function (target, data) {})#on('comment', function (s) {})#on('xmlDecl', function (version, encoding, standalone) {})#on('startCdata', function () {})#on('endCdata', function () {})#on('entityDecl', function (entityName, isParameterEntity, value, base, systemId, publicId, notationName) {})#on('error', function (e) {})-
#stop()pauses -

We don't emit an error event because libexpat doesn't use a callback
either. Instead, check that parse() returns true. A descriptive
string can be obtained via getError() to provide user feedback.
Alternatively, use the Parser like a node Stream. write() will emit
error events.
A word about special parsing of xmlns: this is not necessary in a bare SAX parser like this, given that the DOM replacement you are using (if any) is not relevant to the parser.
