XML Parser for JavaScript - xml2array()
xml2array() parses the given XML document and return the data in an associative array.
See Demo.
Useage
xjx.load("file.xml",function(xmlDoc) {
var arr = xml2array(xmlDoc);
// Do what you want with 'arr'
});xjx Or Xml aJaX is a small library I wrote to load external XML files using the XMLHTTPRequest method. Based on the jx Ajax library. You don't have to use this library to parse the XML file - just load the XML file using the method you are most comfortable with and then call the xml2array function with the XML object as the argument.
Code
The code is given in the xml2array.js file. It is a bit ugly - but it gets the job done. This file also includes the code for the xjx library and the dump function(Javascript equivalent of PHP's print_r function).
The code is somewhat big(100 lines of code) so I am not putting it in this page - just have a look at the js file for the code.
Problems
There are some problems with the script - but this just the first release so it is to be expected.
I have only tested the script in the following browsers. Please let me know how the script worked in other browser's.
- Firefox 1.5 in Linux
- Firefox 1.5 in Windows
- IE 6 in Windows
- Mozilla in Linux
Another problem is that the scripts runs into trouble when such details like XML version(<?xml version="1.0"?>) or stylesheet information(<?xml-stylesheet type="text/xsl" href="softwares.xsl" ?>) or some other extra infomation like <!DOCTYPE programs SYSTEM "softwares.dtd"> is there in the XML file. I am hopping this will not be much of a problem as this script is aimed for use with Ajax responses in XML format - so we can safely assume that there will not be any 'stylesheet' information in it ;-). If you find any solution for this problem, please let me know - my email is moc.liamg@avynnib
Actionscript
I was hoping that I could get this script to work in Actionscript. I don't 'know' actionscript per se - I know javascript and assume that I could code in Actionscript as they have very similar syntax. Unfortunately, the script fails in Actionscript - some problem with the whitespace Regular Expression. If any of you know actionscript, please take a look at the script and if you could get it working in Flash, drop me a line at moc.liamg@avynnib.
License
This script is released in the GPL license.

Any ideas?
I got a problem when I call xml2array function for the second time ( I tried to convert the same 'xml content' for the second time , but it resulted in two different associative arrays .I checked in IE 6 , IE 7, mozilla 1.5, mozilla 2.x browsers) because of the
global variable " parent_count "
It's declared globally
as..
var parent_count = new Object;
So , I changed the above line as
var parent_count ;
//Process the xml data
function XML2ARRAY(xmlDoc)
{
parent_count = new Object;
var arr= xml2array(xmlDoc);
delete parent_count;
return arr;
}
Now, my problem got solved .....
And Thanx for the code ..
There is a problem with the code you have provided - it will not maintain the functionality of this function in large/complex xml files. I have made a small change to your code - you can see it at the updated page of xml2array()
By the way, I have moved this page to my new site - all the updates will be made there.
<mainbla>
<bla_1>asdf</bla_1>
<bla_2>asdf</bla_2>
<amount>3</amount>
</mainbla>
javascript:
var blaArray = xml2array(theXmlAbove);
alert( blaArray["mainbla"]["amount"] );
what I get is:
NOTHING!!
