Re: [xsl] Could not use matches in Regular Expression (XSLT 2.0)

[Jack Bush <netbeansfan@xxxxxxxxxxxx>]

Hi Wolfgang,
 
I am trying to match digits between 420000 to 420016 or 49####
with the following regular expression:
 
   
matches(.,'^(4200[0-1][0-6]{6}|49\d{6})$')
   
matches(.,'^(4200[0|1][0-6]{2}|49\d{4})$')
 
However, XSLT transformation
failed with the following error:
    Exception in thread "main"
java.lang.NullPointerException when the data is 420001.
 
One thing I am still
not clear is what is the total number of quantifier {} when the initial
matching numbers have already been provided? So in the case of value 420001,
should the quantifier be {6} (include total number of digits starting from the
1st 4 (4200) already supplied? Or does it only need to quantify the remaining
{2} variation?
 
The last matching for 49#### is simple since there are no
specific patterns required for the last four digits. As a result, the
'^49\d{6}$' but again, I am not sure whether the quantifier should be {6} or
{2} for the same reason already mentioned.
 
Thanks,
Jack

This could be a single pattern:
   
'^(4\d{6}|6\d{5})$'

There is
no '&' (in this sense) in patterns, and it doesn't make
sense: A string cannot
match both distinct, full range (i.e., from
^/start to $/end) at the same
time. What is the spec, verbally?

The pattern must be a string, so enclose it in apostrophes. (Also,

one opening bracket missing.) To have an exact match, use '^'

anchor at the beginning and the end. You may simplify using
