Given an XSL 'If' statement: <xsl:if test="a = 'some value' and b = 'another value'"> If a does not equal 'some value', is the value of b still checked? (As if the first test is false, the only outcome of the and is false.) This is what languages like C# do - I was wondering if the same goes in XSL. Does it depend on the engine/parser...
How do people generally handle conditional statements in MVC frameworks For some of my pages (made under Kohana) I want the user to have more options depending on whether they are logged in or not, and whether the profile is their own profile for example.

I have a parent child table relationship. In the example below Foo has a FooID and a nullable ParentFooID that points to a parent record. The Bar table is always linked to the parent record.

Sometimes, I feel like it is easier to check if all of the conditions are true, but then only handle the "other" situation. I guess I sometimes feel that it is easier to know that something is valid, and assume all other cases are not valid. For example, let's say that we only really care about when there is something wrong: object va...

The code below is based on this recipe. However, the key point of the recipe - that it provides a way to break out of the iteration on an iterator if the iterator is empty - doesn't seem to work here, instead behaving in the following undesired ways: If get_yes_no_answer() == False and there are two or more items left in the iterator, ...
I am running into an issue when trying to apply an :if condition to a validates_associated validation. The if condition works for validates_presence_of, but not for validates_associated, and the form (with two models in it) works correctly, except that the validation still returns an error, regardless of whether the if condition is true ...

In Stroustrup's The C++ Programming Language: Special Edition (3rd Ed), Stroustrup writes that the declaration and initialization of variables in the conditionals of control statements is not only allowed, but encouraged. He writes that he encourages it because it reduces the scope of the variables to only the scope that they are requir...

Hello, I recently upgraded to xampp v1.7.2 which dumped PHP 5.3 on me. Along with that all my httpd.confs and php.ini's got wiped out (I had taken it for granted that this release will be an upgrade like all the earlier xampp releases). Anyway, it took me a while to reconfigure all the services - but now I've run into a funny problem....
