Not catching error on handler?

[marcelourbanolima]

Hi, I'm not expert in javascript/node so I'm probably doing something wrong but, could someone please help and tell me why the error is not being caught in .on('endElement', f1) when f1 contains errors?

'use strict';

const XmlStream = require('xml-stream')
const fs        = require('fs')

let s1 = fs.ReadStream('node_modules/xml-stream/examples/collect-preserve.xml')

let x1 = new XmlStream(s1)

x1.on('error', () => {console.log('Error never caught')})
x1.collect('subitem')
x1.on('endElement: item', f1)


function f1(xmlItem) {
  console.log('enter function')
//  console.log(undefined.split()) // error never caught
  console.log(xmlItem)
  console.log('leave function')
}

/* expected output:
enter function
{ subitem: [ 'one', 'two', 'three' ], '$text': '1 2 3' }
leave function
enter function
{ subitem: [ 'four', { letter: 'B', '$text': 'five' } ],
  '$text': '4 5' }
leave function

received output:
enter function
*/

Seems like on will swallow all errors. I had to wrap my entire on handler in a try/catch just to see errors.
