Hello, 

I have to analize a text document and want to get all lines like:

>F<a string>F<another string>F<another string>F<                      # 
(where F is a floating point number between the two characters >< )

but only, if all four floating numbers are identical!


Example for a text:

text>text<text
>5.3<abc>5.3<d>5.3<ef>5.3<
>4.2<abc>3.0<d>4.2<ef>4.2<

Here, only the second line is needed.



Some ideas?

Thanks,
Walter
