Subject: how to move on to next url if current one is a dud

hmm wasnt too sure how to make the subject both concise and
understandable at the same time so my apologies if i was vague.

I searched under "ignore missing" but didnt come up wiht anything.
Perhaps someone can help me.

Im using open-uri to fetch the html from various ebay webpages.
Basically the results for certain categories. I have all the relevant
urls tucked into an array of hashes eg. Computers =>
www.ebay.blah.blah.blah

I then cycle through the array feeding open uri the urls and doing my
biz on the html one by one.

However sometimes there are no products for a certain category for that
given day (im focussing on products located in japan so the number of
results is drastically reduced) so when open uri complains like this

ebay.rb:71:in `read': No such file or directory -
http://research.ebay.co.uk/ws/
search/GetSaleAnalysis?sojs=0&salic=104&sacqyop=9&sacqy=1000&sacat=13851&ftrv=17
&fis=2&fts=-1&fn=4&frts=0&sc=AvgSoldPrice&showdiag=0&soexpand=1&soraw=0
(Errno::
ENOENT)

Im fine with it complaining but it stops the programme. How do i make it
simply skip/ignore such urls and move on to the next one in the hash?

any help greatly appreciated.
