Is there any wildcards?

[Henrik Andersson <henrik@xxxxxxxxxxxx>]

Hi!
I wonder if there exists anything in XSL with the function of a
"wildcard"?


For example in the following line...

<xsl:value-of select="substring-before("1999 APRIL 23","APRIL")"/>

Is it possible to put in something instead of "APRIL" as a second
argument to the substring-function?


Like in perl:
"anything"	-	.*
"any digit"	-	\d
"any two digits"-	\d{2}
etc.


Thank you!

/Henrik
