xesearch – A string finder for XeTeX
The package finds strings (e.g. (parts of) words or phrases) and manipulates them (apply any macro), thus turning each word or phrase into a possible command.
It is written in plain XeTeX and should thus work with any format (it is known to work with LaTeX and ConTeXt).
The main application for the moment is XeIndex, an automatic index for XeLaTeX, but examples are given of simple use to check spelling, count words, and highlight syntax of programming languages.
