Обсуждение: Ampersands in the output...
I'm using postgres to return business names via a function. In the function I "xml-ify" the output by taking the name and wrap it with start/end tags, as in "<name>name</name>" (there's a lot more to this and I'm simplifying greatly). However, the problem is that some of the names have "&" in them, like "Joes Bar & Grill", which really should be escaped in XML. Any ideas how to escape those things before they get to the recipient (i.e. my application, IE, Mozilla, etc.)? Is there a built-in function or something I could make use of? I suppose I could write a little more code in my function to look in the field and try to do a string replace or something, but is that the most efficient method? Thanks in advance! :-) Bret
Hi Bret,
That sounds most likely served best at the application layer - for
example, if your application is written in PHP, you can use the PHP
function:
http://us3.php.net/htmlentities
You can also use regular expressions or PHP's str_replace to just
replace all instances of '&' with '&'.
Pretty sure other languages have their own methods as well.

Thanks, Mitch. Yes, you're right, I can definitely do it in the calling servlet, but I was wondering if there's an easy way to do it in Postgres. I'll take care of it in Java, then :-).

There is always pl/php or pl/java, if you really want to put the code in the backend. --- "Schuhmacher, Bret" <Bret.Schuhmacher@Aspect.com> wrote: > Thanks, Mitch.
