Re: [xsl] Regex in @select Escaping Puzzle

Thanks--Martin's solution seems like the easiest to work with and it works for 
me. I didn't even consider putting the expression into a variable to avoid the 
worst of the double escaping heck.

Cheers,

E.

    And to be safe in XSLT 3 in any context you probably want

    <xsl:param name="pattern"
    as="xs:string"
    expand-text="no">\{\{image_[^}]+\}\}([^{]+)\{\{/image\}\}</xsl:param>


    otherwise the use of expand-text="yes" higher up the tree causes the
    same problem you run in with using the regular expression in the attribute.
