npm install node-xml-slicer

Quick start

Following simple snippet parses given XML string using node-expat parser and transforms it using 2 separate Slicers. You can combine as many Slicers as you want, extracting different parts of XML in one go.

var expat = require('node-expat');
var Slicer = require('node-xml-slicer');

var parser = expat.createParser();

var rootSlicer = new Slicer(parser);
var itemSlicer = new Slicer(parser, '/root/items/item');

parser.write('<root><items><item id="1">value 1</item><item>value 2</item></items></root>');

console.log('%j', rootSlicer.result);
console.log();
console.log('%j', itemSlicer.result);

Output of this code would be:

{
    "root": {
        "items": {
            "item": [
                {
                    "#": "value 1",
                    "id":"1"
                },
                "value 2"
            ]
        }
    }
}

{
    "item": [
        {
            "#": "value 1",
            "id":"1"
        },
        "value 2"
    ]
}
