Curly braces are special in AVTs and they are special in regexes. To cope with the specialness in AVTs, double them, To cope with the specialness in regexes, backslash-escape them. So regex = "\{{[a-z]+\}}" should do the trick; or as Martin suggests, remove the AVT problem by using a variable (making sure you have expand-text="no") Michael Kay Saxonica > On 17 Nov 2020, at 12:43, Don Smith dsmith_lockesmith@xxxxxxxxx <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> wrote: > > Once again I find myself at a loss when trying to write a regex in analyze-string that matches on an open/close curly brace combination.

No expression before quantifier". I've tried everything I can think of in terms of using escapes, etc. I've also tried defining the regex as a variable and then referencing it from @regex. But I'm just missing something in the regex itself (I think).
