Thanks for all your answers.
R is correct with his assumptions - sorry for the confusion.

So let me post it again, easier

I have a beginning of a (longer) string who is like:
mystr =  '<mimetype="text/html"><content><![CDATA['
or like
mystr =  '<mimetype="text/html" ><content><![CDATA['
or like
mystr =  '<mimetype="text/html" >
          NewLine <content><![CDATA['

I want to have the end-position of the mimetype tag (position as
mystr.find('>') returns, so I can use the number for a loop)
However, I can't use just the '>' because the character > could also
be in the string of mimetype (I know, actually not in mimetype, but
let's assume it).
So that is why the filter shall be bulletproof and check for '">' -
with possible spaces between both characters.

I don't know yet how to solve this issue - any recommendations?
