For example The address line is like this: melkweg 51a.
This means I have to map this like this: street = melkweg, number = 51,
extension = a
Are there such wildcards, and/or is there a better way to do this?
Hi Pankaj,
Yes, there's a better way. As a matter of fact, this happens to be a
specialized field of science. Depending on your needs, there are
numerous ways to resolve this. Since you appear to live in Holland and
the address exists in Amsterdam, consider the following address lines:
1) Melkweg 51 A
2) Plein 40-45 123-IV
3) 1ste J vd Heijdenstraat 12-hs
ad 1) this is a common extension
ad 2) street is "Plein 40-45", nr is "123", suffix (floor) is "IV"
ad 3) suffix 'hs' means 'huis' means ground floor in Holland. Note the
number in the streetname.
Perhaps you'd thought of all this already. International addresses pose
even more challenges: the French and the English place their
streetnumbers as ordinals as start of the address line. I hope you won't
have to deal with non-western characters or hebrew digits.... Hopefully
nobody entered the postal code or city name on the same line ;-)
(that's why postal companies offer products to normalize the addresses
to some well-known format. But beware, they offer about 95% matches, the
rest will still dropout)
Now, for a solution with XSLT 1, it will be quite a challenge. I think
you will have to pass the address line multiple times through the
translate-filter that was proposed by Michael.
When you can resort to XSLT 2 or a filter before processing (like with
client-side, you may be able to use javascript + regular expression to
filter, on server side, you may use java/.net/perl/php + regular
expression to filter your data), the regular expression may look like
this (needs tweaking):
^(.*) ([0-9]+)([ -]?([a-zA-Z]))?$
$1 contains streetname
$2 contains number
$4 contains suffix (use $4 if you want it to include space or hyphen)
The regex will work for the above three examples (spaces are important
in the regex).
