l3regex – Regular expression facilities for LaTeX
The package provides regular expression testing, extraction of submatches, splitting, and replacement, all acting on token lists. The syntax of regular expressions is mostly a subset of the PCRE syntax (and is very close to Posix), with some additions arising from the fact that TeX manipulates tokens rather than characters.
For performance reasons, only a limited set of features are implemented. Notably, back-references are not supported.
The package is currently distributed as part of the LaTeX3 l3kernel bundle.
