Hi,

What's the right expression to find exponent and argument in:
sin²(B/2 - C/2) ?

I need to change it to: sin(B/2 - C/2)^2

I've tried with "(sin|cos|tan|cot|sec|csc)^(\d)+\(*\)" but
this string is not compiled with Wild2RegEx()

Also, I tried with "(sin|cos|tan|cot|sec|csc)^(\d)+(*)".
This is compiled by with Wild2RegEx() but element in HB_RegExAll()
loses the right ")"

Thanks a lot in advance
Cesar Lozada

Please remember that ( and ) and * symbols are meta-characters, and need to be escaped.

Additionally the * symbol IS NOT have the meaning "whatever" string.

Please think about this:
- include your variable expressions in SPAN tags (or other similar) and use a CLASS or ID attribute for that tag, in order to identify it
- when you want to change the SPAN's content, just extract the data string, and pass in another data string

Best regards.
