General IE question

[Champak]

Two question on getting information from a website.

1/ Is it faster to go straight for an index number when of getting tags/tables/collections than doing a loop style like:

For $oElement In $oElements
     If something = something Then
          do something
     EndIf
Next

2/ Is it smarter to do the loop style because the website my change up the layout?

Thanks

1. Indexing is faster if you know in advance what indexes you need to visit, so you don't have to waste time enumerating values that you do nothing with.

2. If the site changes, you may have to stick with the loop.

XPath would be more convenient than enumeration, but I don't think IE supports XPath natively.
