Re: Re: [xsl] Need an XPath expression which returns all xs:pattern elements containing a regex that permits an unbounded number of characters

You didn't supply an example expression like that in your initial query.
There's an awful lot of permutations of unbounded expressions. You could use
more groups and "or" bars? Good luck!

Hello Edward,



>>> matches(@value, '[a-zA-Z]+(\*|\+|\{\d(,.\})?)')



That assumes the regexes are all of this form:



<xs:pattern value="A*"/>



However, there are other forms that permit an unbounded number of characters,
such as:



<xs:pattern value="[0-9]{3}D*[ABC]"/>



That regex permits an unbounded number of D symbols.



I need an XPath expression that can detect an unbounded number of characters,
regardless of the complexity of the regex.
