So it must be escaped as \{. So the regular expression you want is (\w|\{[^{}]*\})+ which is written in the regex attribute as regex="(\w|\{{[^{{}}]*\}})+" It might be less painful to do: <xsl:variable name="regex">(\w|\{[^{}]*\})+</xsl:variable> <xsl:analyze-string regex="{$regex}"> though sadly, I suspect that will prevent Saxon precompiling the regular expression :-( Better idea: use chevrons instead of curlies.
