in thread reset named capture buffer within regex
the purpose is matching sequences (variable length) of tokens out of a larger list (variable length) of tokens with each token carrying a number of additional attributes (e.g. number) that qualifies it as part of a token group, e.g. A1 B1 b1 B1 b2 C2 c2 d3 D3. For example, looking for sequences of B|b that are part of the same (number) group. Results here: 'B1 b1 B1' and 'b2'. Unfortunately, it is no option to slice the sequence by the 'group' (number) attribute and do the token matching on every subgroup, because there are other attributes on the tokens that bridge the groups and are being considered in the overall expression (to complex to show here). The philosophy of the current pattern attempts to match a token sequence, loads the group attribute of the first token in <mybuf> and continues matching using <mybuf> as a target for attributes of upcoming tokens. This works perfectly, however I need the option to break this sequence (reset <mybuf> without actual match) in certain cases.
