Re: [xsl] XSLT Regex for Matching Curly Braces

 Thank you all,
I used Gerrit's suggestion <xsl:analyze-string select="." 
regex="\{{([^}}]+)\}}"> and it appears to work exactly as desired. Further 
testing TBA.
Thanks again,
Don

 Agree, if expand-text is available (if one uses XSLT 3.0, for which there is 
almost no reason not to).

If you want to use xsl:analyze-string with XSLT 2.0 (or 3.0), you can put the 
regex in a variable, like so:


  <xsl:variable name="regex" as="xs:string" select="'\{([^}]+)\}'"/>


I think it's even clearer to use

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




This way you avoid complications with single and double quotes as well as curly 
braces: the only characters that now have an XML or XSLT-defined special 
meaning are "&" and "<", and these fortunately don't have special meanings in 
regular expressions.
