i think what M_H wanted was to find the second occurance of ">" char
in  mystr.
Now if mystr will always look exactly as show then Jorgen Grahn's re
will work fine. But it looks to me that the poster only showed us a
portion of the string, and as you can see the <mimetype tag is not
closed in mystr, which would break your re, if the string acually
extends further. Split would be fool-proof in all situations. But then
again i had to read the post 5 times before i understood it. It may be
advisable for M_H to repost the question in a clearer manner so that
we can be sure our answers are correct!
