Thank you Martin for the solution. Thank you Dr. Kay for the summary reminder: To cope with the specialness in AVTs, double them, To cope with the specialness in regexes, backslash-escape them. So regex = "\{{[a-z]+\}}" Don On Tuesday, November 17, 2020, 07:43:44 AM CST, Michael Kay mike@xxxxxxxxxxxx <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> wrote: Curly braces are special in AVTs and they are special in regexes.

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. DonXSL-List info and archiveEasyUnsubscribe(by email) XSL-List info and archiveEasyUnsubscribe(by email)
