perfomance issues of dynamically removing node from document

[jambalapamba]

Hi

I am removing node from a document depending on the style property and this is taking 7 seconds for checking complete document is there any ideas how can i improve the perfomance. Here is my part of code

foreach (IHTMLElement tempElement in document.all)
{
if (tempElement.st yle.visibility == "hidden" )
{

IHTMLDOMNode node = tempElement as IHTMLDOMNode;
node.parentNode .removeChild(no de);

}
}

the for loop is taking more than 7 seconds for a relatively big document(not huge)
