How to parse through the HTML and get the values.

[kst]

Hi ,
I have a javascript in which i am able to get the HTML view of the datagrid(which has 4 row and 4 column),
It shows the each and every textbox and columns in table format,
I used the

var len1=obj.parentElement.parentElement.parentElement .parentElement.innerHTML;
alert("first:"+len1);

to see that HTML view,
Here obj is got from the event in ASP.Net,

I want to know how can i get the value from the HTML page,
When i used the firstElement or nextElement with the parent Element,
the error is that "null or not an object",

What type of command i should use to parse through the HTML,


Thanks

hi ...

you may use:

document.getElementById(id) - for getting a ref to an element (node)
node.nextSibling - gives you the 'right' neighbor
node.previousSibling - gives you the 'left' neighbor
node.parentNode - gives you the parent
node.firstChild - the first child node
node.lastChild - the last child node
...

have a look for dom-scripting, -navigating ... good link is here:
