XMLParser.js

A simple javascript XML parser I made to process some xml files, such as:

Basic xml files (configuration files, etc.)
GPX files with GPS data

It has not been thoroughly tested so don't expect to be able to parse too complex xml files. Also, there is a lot of room for improvement (performance and memory wise).

Usage

As a node.js module

Add the following line at the end of the XMLParse.js file to export the XML parser:

module.exports = new XMLParser();

Given the following books.xml file (source: http://msdn.microsoft.com/en-us/library/ms762271(v=vs.85).aspx):

<?xml version="1.0"?>
<catalog>
   <book id="bk101">
      <author>Gambardella, Matthew</author>
      <title>XML Developer's Guide</title>
      <genre>Computer</genre>
      <price>44.95</price>
      <publish_date>2000-10-01</publish_date>

      with XML.</description>

   </book>
   <book id="bk103">
      <author>Corets, Eva</author>
      <title>Maeve Ascendant</title>
      <genre>Fantasy</genre>
      <price>5.95</price>
      <publish_date>2000-11-17</publish_date>
      <description>After the collapse of a nanotechnology 
      society in England, the young survivors lay the 
      foundation for a new society.</description>
   </book>
   <!-- and so on -->
</catalog>

Include the module in your node.js file, read the book.xml file and pass the text to the parser's load function:

var fs = require('fs');
var parser = require('XMLParser');

fs.readFile('/home/user/downloads/books.xml', 'utf8', function (err, data) {

    if (err) {
        return console.log(err);
    }

    var dom = parser.load(data);

    dom.getElementsByTagName("book").forEach(function(book) {

        var line = "",
            title = book.getElementsByTagName("title"),
            author = book.getElementsByTagName("author"),
            genre = book.getElementsByTagName("genre");

        line += title[0].innerText + "; " + author[0].innerText + "; " + genre[0].innerText;
        console.log(line);

    });

});
// Outputs:
//
// XML Developer's Guide; Gambardella, Matthew; Computer
// Midnight Rain; Ralls, Kim; Fantasy
// Maeve Ascendant; Corets, Eva; Fantasy
// Oberon's Legacy; Corets, Eva; Fantasy
// The Sundered Grail; Corets, Eva; Fantasy

As a standalone library

Include the file in your html page:

<script type="text/javascript" src="XMLParser.js"></script>

Then use it in your javascript section:

var parser = new XMLParser();

var xmlString = "<book><title>A Game Of Thrones</title><author>George R. R. Martin</author></book>";

var dom = parser.load(xmlString);

dom.getElementsByTagName("book").forEach(function(book) {

    console.log(book.getElementsByTagName("title")[0].innerText);
    // Outputs: A Game Of Thrones

    console.log(book.getElementsByTagName("author")[0].innerText);
    // Outputs: George R. R. Martin

});

Note: consider using a minified version.
