Extracting information from (La)TeX source files

Abstract

We present some tools that allow us to parse all or part of (L A )TEX source files and process suitable information. For example, we can use them to extract some metadata of a document. These tools have been developed in the Scheme functional programming language. Using them requires only basic knowledge of functional programming and Scheme. Besides, these tools could be easily implemented using a strongly typed functional programming language, such as Standard ML or Haskell.
