I have a date element:
example
<DATE>11/01/2006</DATE>
By induction from the examples below, I guess this is 1st November? I'll try
to exercise the necessary mental gymnastics.
I'm trying to write an XPath 2.0 Regex to winnow some of the
more obvious date format errors. I have tried for about a
half-hour, and I admit to being stumped.
Here is the relevant part of the template:
<xsl:when
test="matches(DATE,'[0-1][0-2]/[0-3][0-9]/2006')"><bad-date
/></xsl:when>
These dates passed the test:
<DATE>07/18/2006</DATE>
<DATE>07/12/2006</DATE>
<DATE>09/25/2006</DATE>
I assume that "passing" means they didn't match the regex, and therefore
didn't output "<bad-date/>"? More gymnastics...
While these failed:
<DATE>10/24/2006</DATE>
<DATE>10/18/2006</DATE>
<DATE>10/10/2006</DATE>
<DATE>10/02/2006</DATE>
<DATE>01/19/2006</DATE>
It appears any value with a "1" in either the first or second
position is failing.
No, any value with a digit other than [0-2] in the second position is
"passing". Which is what you asked for.
If the first two digits are supposed to be MM, that is, in the range 00 -
12, then the second digit can range from 0-9. If you want a precise test,
write
(0[1-9]|1[0-2])
