Dear List,
Is it possible to use an XSL variable in a regular expression when using the
"matches" function in an XSL transformation?
Say I have
<xsl:variable name="Prefix" as="xs:string" select="'PR'"/>
Then I want to use $Prefix in my regular expression like I might use XSL
variables elsewhere:
matches(normalize-space(text()[1]), '^(optional beginning text)*$Prefix:
[a-zA-Z ]*')
$ is a special character in regular expressions. I haven't found examples of
variables in regular expressions in my internet searching.
I'd like to match text that starts with 'PR', such as "PR1234: Some problem to
report".
I'd also like to match text that may have some other initial characters, then
the 'PR' prefix and more text, such as "optional beginning text PR9876: Another
problem".
I could put the literal 'PR' in the regular expression, but I was hoping to
factor that out for use in a few other regular expressions, and have only one
place to edit if the prefix string changed.
Thanks for suggestions, or letting me know this can't be done.
Sincerely,
Mike Cook
