Oh, thank you very much.
Yes, it works and is much quicker than the earlier version of the recipe.
You are right that the earlier version picked up a lot of junk. I assumed that it was just part of the process and could not be eliminated. The revisions that you kindly made have removed a lot of that junk but, interestingly, along with the articles it now picks up some other stuff which is rather junk-ish
But that doesn't stop me from being able to read the articles and I understand completely that it is almost impossible to understand a Japanese web site without understanding the language. So thanks again for your efforts they are very much appreciated.
I had a look at the recipe via the link you sent and I'm afraid it is quite alien to me so I'm not able to add anything of value in terms of cleaning it up further.
Thanks a lot. You've cheered-up my day!
