Question

The following code works perfectly.

@doc = open(link) { |f| Hpricot(f) }

But I want to use the following code, which doesn’t seem to play well with the Hpricot block (e.g. @doc is a TempFile object, not a Hpricot document object)

@doc = resolve_link(link) { |f| Hpricot(f) }

def resolve_link(link)
  begin
    return open(link)
  rescue
    logger.debug("#{$!} for link #{link}")
    raise Exceptions::ErrorResolvingLink.new("Cannot resolve link #{link}.")
  end
end

Any idea how I can get the second version of the code to work?

You’re calling resolve_link with a block but you’re not passing that block down to open. Try this instead:

def resolve_link(link, &block)
  begin
    return open(link, &block)
