Hi there,
Questions here (or on the mailing list) are fine!
What you're asking for is capturing group support, which Hyperscan does not support. Hyperscan will only provide the end-offset of a match, or both the start- and end-offsets if you use the HS_FLAG_SOM_LEFTMOST
flag.
Probably the best way to do what you're trying to do with Hyperscan is to perform some further processing in the match callback when Hyperscan finds a match. Depending on how stylized your patterns are, you could use some sort of string matching (as you've suggested), or a single-regex matcher that supports capturing groups, like PCRE, to extract the sub-match data you need.
