[jQuery] how to search/replace text nodes?

[jQuery] how to search/replace text nodes?


I want to iterate over all text content in my document in order to
replace certain text with other. It isn't safe for me to just work
with the $().html() if the entire document because I might
accidentally match and replace some of the non-textual content, eg
values of attributes. I've been unable to use the obvious approach of
filtering on nodeType=3 in order to get just the text nodes. I am not
sure if it is related to this reported issue:
http://www.nabble.com/Bug:-1.3_b1-selector--nodeType%3D3--not-working-td21286366s27240.html
Can anyone explain whether there is a way to accomplish what I want to
do?
Thanks
