Hi,

Is there a .NET compliant, yet stream-based regex-implementation available

The regex implementation in System.Text.RegularExpression is very useful and I use it regularly.

However, more often than not (e.g. today) I find myself reading an entire file or buffering a chunk of streamed data, just to capture some comparably small pieces of information.

If there was an Regex implementation based on Stream/TextReader, using events to convey group captures, I could reduce the memory needed for the buffering as well as the time and I/O to read data beyond my area of interest.

Searching the community I found no mention of such a thing.

I understand that backtracking and the like would still require buffering or pose restrictions on either the usable Stream or available regex language elements.

However, I would find a SAX-like regex implementation incredibly useful.

Would anybody disagree
