processor signature not working for me

[myfygx]

I wrote something like this:

function parseNumberProcessor(value, key) {
console.log("My NODE: "+ key + " My value: "+ value);
let isNumberNode = true;
if ('account' === key) {
isNumberNode = false;
}
if ((!isNaN(value))&&(isNumberNode)) {
value = value % 1 === 0 ? parseInt(value, 10) : parseFloat(value);
}
return value;
}

const xml = '0012345123.45';
xml2js.parseString(xml, {
valueProcessors: [parseNumberProcessor]}, function(err, result) {
console.log(result);
}
);

And the console out put is:
My NODE: undefined My value: 0012345
My NODE: undefined My value: 123.45
{ account: { accountNumber: [ 12345 ], balance: [ 123.45 ] } }

Seems valueProcessors could not accept the signature for value and key. But in the test, I see there is a similar test passed, not sure how could I handle that

Seems xml is not displayed correctly, it's the same as in the test
0012345123.45

I am having same issue, trying to pass
{
attrValueProcessors: [myFunc]
}

where
function myFunc(val, key) {
console.log(key);
return val;
}

key is undefined..

Same for me

Can you post a minimal, working example?

[npopov-d3]

Thank you,

var parseString = require('xml2js').parseString;
var xml = "<root attr='zzz'>Hello xml2js!</root>";

function foo(val, name) {
console.log("called with", val);
console.log("but the name is", name);`
if (name === 'attr') {
console.log('eurika!');
}
return val;
}
parseString(xml, {
attrValueProcessors: [foo]
}, function (err, result) {
console.dir(result);
});

produces:
node try.js
called with zzz
but the name is undefined
{ root: { _: 'Hello xml2js!', '$': { attr: 'foo' } } }

environment
node 6.9.2
package.json:
...
"dependencies": {
"xml2js": "^0.4.17"
}

Any updates on this? I have the same issue. It seems like the key is not passed.

According to the docs in readme this should work, but does not for me.

The attrValueProcessors and valueProcessors options accept an Array of functions with the following signature:

function (value, name) {
  //`name` will be the node name or attribute name
  //do something with `value`, (optionally) dependent on the node/attr name
  return value
}

I'm having the same issue. Using this signature for the valueProcessors function, value has the correct value but name is always undefined.
function (value, name) { return value }

I can't reproduce this problem with xml2js 0.4.19. I guess it has been fixed.

Content of test.js:

const xml2js = require('xml2js');

let xml, js;

xml = "<root attr='zzz'>Hello xml2js!</root>";

function foo(val, name) {
  console.log("called with", val);
  console.log("but the name is", name);
  if (name === 'attr') {
    console.log('eurika!');
  }
  return val;
}

xml2js.parseString(xml, {
    attrValueProcessors: [foo],
  }, function (err, result) {
    console.dir(result);
});

Output of node test.js:

called with zzz
but the name is attr
eurika!
{ root: { _: 'Hello xml2js!', '$': { attr: 'zzz' } } }

I think this issue can be closed.
