Extracting reStructuredText References with Emacs Regexes

This post demonstrates how to extract reference targets from a reStructuredText file using Emacs regular expressions and ELisp functions. The author first defines a regex to match references, then uses the `re-search-forward` function to find matches and `match-string-no-properties` to extract the matched reference target. Finally, an ELisp function is written to automatically extract all references, with a complete code example provided.
