Re: [boost] [regex] number of back references

Hi

is there any plan to support more than 9 back references in the regex library?

You can have as many marked sub-expressions as you want, and refer to them in the match_results structure once you have a match. What you can't do at present is have a true back-reference say \12 in your expression. This is basically a problem with the regex syntax, so if you know of a good syntax extension that's already in use then it would trivial to support this. John.
