Hi all
I want to walk with Nokogiri through the whole DOM of an HTML document
and want to do some stuff to the elements; then save the whole DOM again
(with the changes applied).
I need something like that:
dom.each do |tag|
if tag.type == "a"
# do some stuff to links!
if tag.type == "p"
# do some stuff to paragraphs
if ...
end
end
Sadly I don''t really know how to do this, I''m not very used to
XPath and
stuff...
Thanks
Josh

But I''m a bit insecure with the conecpt behind Nogokiri - when I iterate over elements of a DOM and apply changes to them, are they altered within this DOM? I suppose so... And how can I save the DOM back to HTML? Thanks a lot for help Josh -- Posted via http://www.ruby-forum.com/.

Why don''t you read the docs, experiment, and/or ask on the Nokogiri discussion forums?> > Thanks a lot for help > JoshBest, -- Marnen Laibow-Koser http://www.marnen.org marnen-sbuyVjPbboAdnm+yROfE0A@public.gmane.org -- Posted via http://www.ruby-forum.com/.
