Convert HTML Dom Nodes TagNames into Nested String

Requirements:

A Function coded in JS ECMAScript 5.1 (no jquery) is passed an HTML dom node.

The function needs to iterate through the whole dom structure of that node and all nested childnodes.

Use a counter starting from one with prefix 'n' and build an ordered string containing the nested TagNames and textContent represented by the counter and nested square brackets and return the string.

Text nodes, br and any other empty tagNames have an opening and closing bracket [] in the finished string.

Example:

<div id="start">1111<div>2222<div>3333<div>4444<h3 style="text-align: center;"><span style="font-family: 'Lora',georgia,'times new roman',serif;">Example</span>7777</h3>5555<br><h3 style="text-align: center;">6666<span style="font-family: 'Lora',georgia,'times new roman',serif;">Text</span></h3></div></div></div></div>

[login to view URL](htmlMap([login to view URL]('start')));

(testing purposes use tagName and textContent)

DIV[aaaa[]DIV[bbbb[]DIV[cccc[]DIV[dddd[]H3[SPAN[Example[]]eeee[]]ffff[]BR[]H3[gggg[]SPAN[Text[]]]]]]]

(actual result)

n1[n2[]n3[n4[]n5[n6[]n7[n8[]n9[n10[n11[]]n12[]]n13[]n14[]n15[n16[]n17[n18[]]]]]]]

FYI:

The html used will be varied with many different nested childnode structures, however the html will only use the following tagNames.

tags = ['a', 'br', 'blockquote', 'div', 'em','h1', 'h2', 'h3', 'h4', 'h5', 'h6','hr', 'i', 'img', 'li', 'ol', 's','span', 'strong', 'style', 'table', 'td','text-align', 'title', 'tr', 'txt', 'u', 'ul'];

Note:

In the function, plesae include an if else statement checking for nodeType 1 and nodeType 3, as I will need to expand the code to do additional tasks.

This task is required ASAP

Thanks
