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")

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. I'm
using XSLT 2.0 and Saxon PE-9.6.0.7.
Here's an example of the text content:
<text>In the be{opthyphen}gin{opthyphen}ning</text>
I need to match all occurrences (none nested) of an open and close curly
brace with the text that occurs in-between.
I started with this successful regex in a non-XSLT context:
{[a-z]+}
Then because the analyze-string @regex is an AVT I double the curly braces:
{{[a-z]+}}
thus:
<xsl:analyze-string select="$content" regex="{{[a-z]+}}" >
That produces the compile error "Syntax error at char 0 in regular
expression. 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). All help is appreciated.
