Re: [Boost-users] Regex assign raising exceptions

I think I got past it now.

 

Had to change the alternation operator in the middle from 

(|-)

to

(?:)|-

 

Cheers,

Josh

Subject: [Boost-users] Regex assign raising exceptions

 

Hi everyone,

I am having some issues with the boost::regex assign method.

 

I have been following an example on the boost site for a search and
replace.

However I seem to be getting an Empty Expression exception when
assigning my expression to my boost:regex object. 

 

boost::regex exp; 

const char* expression_string = "([[:space:]](|-)[[:digit:]]+)f;"; 

exp.assign(expression_string); 

 

Any ideas?

I have tried a few different syntax option types at the end without
success.

 

Thanks

Josh
