[jQuery] Xpath and length() doesn't seem to work under IE7?

[jQuery] Xpath and length() doesn't seem to work under IE7?


This isn't a problem as such, just something I'm curious about.
Under IE7 I've found that when I use xpath, the length() method
doesn't seem to work, but size() does.
E.g.
$( '//td[@class= "indexL2"]//a').length(); doesn't seem to work, but $
( '//td[@class= "indexL2"]//a').size(); does.
I was just wondering why that is? Is it something to do with the fact
that the xpath has to be converted to regular DOM getters for IE in
the jquery code?
