I am trying to implement in XSL a *set-intersection* "function" in the form of
a template. It should accepts two sequence parameters and return a sequence parameter.
The application for this function will be to argument values that contain space delimited
lists like this:
XML:
<skill category="database software">oracle pl-sql package functions and stored
procedures</skill>
XSL: (test "database software" for any match in "database sysadm")
<xsl:template match="
exists(
setintersect(
tokenize(skill/@category,' '),
tokenize('database sysadm',' ')
)
)
">
I don't understand why you put exists() into a match attribute. That
attribute is supposed to take a pattern, not an abitrary XPath expression.
As for the expression
exists(setintersect(
tokenize(skill/@category, ' '),
tokenize('database sysadm', ' ')
))
when you test
tokenize(skill/@category, ' ') =
tokenize('database sysadm', ' ')
then that expression gives true if at least one item in the left
sequence is the same as one item in the right sequence so that seems to
check what you want to check with your exists expression.
