split using boost::is_any_of confuses over delimeter ",," and ","

Question

I currently have a string that has the following structure ``` xxx,xxx,xxxxxxx,,xxxxxx,xxxx ``` Now I am using the following code ``` std::vector< std::string > vct; boost::split( vct, str, boost::is_any_of(",,") ); ``` Now the boost splits up the string once it finds "," and not ",," which I dont want. Is there any way that I could explicitly specify that it should split only if it finds ",," and not ","

Accepted Answer

`is_any_of(",,")` will match anything that's specified in the list. In this case either `,` or `,`

What you are looking for is along the line of

```
boost::algorithm::split_regex( vct, str, regex( ",," ) ) ;
```

split using boost::is_any_of confuses over delimeter ",," and ","
