An article on how to declare an XML element as NULL using the attribute "xsi:nil". I'm going to use a very short example by providing a blank date of birth value:
- -- What I have:
- <DATE_OF_BIRTH />
- -- What I want:
- <DATE_OF_BIRTH xsi:nil="true" />
- <DATE_OF_BIRTH_EUROPEANFORMAT xsi:nil="true" />
Outputting from SITS:Vision to our staging environment, the application would only output blank values using single tags so we had to find a place to introduce it. On strings this has little worth, but on dates which could be NULL, this was necessary (unless we interpreted dates as strings which we don't want to do):

There are a lot of articles & posts out there that cover the same topic, but as this took me the good part of an hour just to find out, I'm posting it here so I never have to look for it again.
A client changed their website domain address and wanted any person visiting the old domain to be redirected to the new domain.
I warned that a 301 site gets removed from the Google directory and true to form Google have removed it. Not sure why nobody believed me when I raised the alarm but hey-ho.
I'm going to show you how to do this with a .htaccess file:
A note for myself on some code to convert a string of two names into a string made up of the first name and then using the initial of the second name.
- -- What I have
- John Smith
- -- What I want
- John S.
- Fred B.
A quick note on a htaccess rewrite rule I'm liking.
What does it do?
What I type:
Thank You! :c)
