Обсуждение: HowTo divide streetname from house-nr ?
Hi, how could I divide streetnames from housenumbers ? I have to deal with input like this: Parkstreet 42 Parkstr. 42 Casle Avenue 42 Casle Str. 42-47 Casle Str. 54 - 55 probaply even Casle Str. 42-47 a Perhaps one could cut ap the 1st numeric char and regard everything left of it as the street name and the rest as house number. OK, this would fail with "42, Parkstreet" but those aren't to frequent. How would I do this?

There are papers written on the subject of addressing, address analysis, addressing in databases, etc. How would you handle the address: Person's Name RD3 Clemo Rd Whangarei ? "RD3" is "Rural Delivery Area 3". The posties deliver within the area by named recipient. This is a real address scheme. The world is full of weird and wacky addressing. IMO, unless you're willing to confine your schema to only handling addresses of a particular area you know about, don't try to normalize address. Even then, I wouldn't try to normalize addresses with text processing, I'd ask the user to do it during form entry or not do it at all. If you're trying to find duplicate addresses, matching addreses, etc, then IMO you're better off using existing tools that do this with free-form addresses using national phone databases, postcode databases, etc. -- Craig Ringer Tech-related writing at http://soapyfrogs.blogspot.com/

<br /> The only chance I see is to combine the information about the localization with the address pattern. <br /><br />regards<br /><br /> Andreas<br /><br /><br /><br /><br /> On 09/23/2010 09:12 AM, negora wrote: <blockquote cite="mid:4C9AFDEC.3050601@negora.com"type="cite"></blockquote><font face="Verdana">I guess that it's impossible to lookfor a solution which works on every </font>existing case, specially if you're handling addresses from several countries.However, if you've certain control over the user inputs, maybe you could try replacing certain parts employingsome kind of regular expression which removes numbers at the beginning/end of the string.<br /><br /> On 23/09/1003:25, Andreas wrote: <blockquote cite="mid:4C9AAC85.1000001@gmx.net" type="cite"> Hi, <br /><br /> how could I dividestreetnames from housenumbers ? <br /><br /> I have to deal with input like this: <br /><br /> Parkstreet 42 <br />Parkstr. 42 <br /> Casle Avenue 42 <br /> Casle Str. 42-47 <br /> Casle Str. 54 - 55 <br /><br /> probaply even <br />Casle Str. 42-47 a <br /><br /> Perhaps one could cut ap the 1st numeric char and regard everything left of it as the streetname and the rest as house number. <br /> OK, this would fail with "42, Parkstreet" but those aren't to frequent. <br/><br /> How would I do this? <br /><br /></blockquote><br />
