SYNOPSIS

Node.js:

var fromXML = require("from-xml").fromXML;

<script src="https://rawgit.com/kawanet/from-xml/master/dist/from-xml.min.js"></script>

Run:

var xml = '<xml foo="FOO"><bar><baz>BAZ</baz></bar></xml>';

var data = fromXML(xml);

console.warn(data.xml.bar.baz); // => "BAZ"

console.warn(data.xml["@foo"]); // => "FOO"

    }
  }
}

XML:

<xml>
  <foo/>
  <bar></bar>

</xml>

    "bar": "",
    "qux": {
      "@quux": "QUUX"
    }
  }
}

    "foo": ["BAR", "BAZ", "QUX"]
  }
}

Text Node with Attribute

XML:

<xml>
  <foo bar="BAR">
    BAZ
  </foo>
</xml>

JavaScript:

{
  "xml": {

    {
      "foo": [
        {
          "@bar": "BAR",
          "#": "BAZ"
        }
      ]
    }
  ]
}
