Re: Calling context node E4X functions inside filter expression.

Hi,

You can achieve similar results by defining a custom filter function. Something like:

function filter(list, predicate) {

    var result = new XMLList();

    var k = 0;

    for (var i = 0; i < list.length(); i++) {

        if (predicate(list[i])) {

           result[k++] = list[i];

        }

    }

    return result;

}

And then calling it:

  var filteredList = filter(e4xList.item, function(x){return x.childIndex() < 3;});

Not as elegant as the one-line filter, but works.

Hope this helps,
