Nested patterns is something where gema really excels. Here is a gema script to convert \footnote{{something}} to \footnote{something} :\\footnote\W\{\{<matchbrace>\}\}=\\footnote\{$1\} matchbrace:\{#\}=\{#\} matchbrace:\\<Y1>=\\$1 Save it as footnote.gema and then run gema -f footnote.gema tex-file > output-file It handles these expressions correctly: \footnote{{This $\frac{a}{b^{c+d}}$ is a strange footnote}} \footnote{{This $\frac{a}{b^{c+d}}$ is a strange footnote with multiple {nested {expressions}}}} \footnote{{This $\frac{\left[\frac {a}{b}\right\}}{c}$ is a strange footnote}} It is much easier to write than regular expressions. Unfortunately, gema expressions can be as hard as regular expressions to read.
