How To Use A Transformer

Two things: 1) transformers don't work on DC - you need to replace the DC power supply with an AC supply, and 2) for some reason you've placed a dead short between the primary and secondary of the transformer. Nothing works if you short it out.

I see, I assumed it did work with DC because I opened up a xenon flash lamp device (Canon MR-14EX - for flash photography) with a +6V DC power supply (4xAA batteries in series). It has a transformer, providing ~300V (I assumed DC) to the xenon tubes.

Would the +6V DC have to be converted to +6V AC, in order to step up through the transformer? How might that conversion be achieved?

As you summized, the dc would first be converted to, AC then boosted. http://everycircuit.com/circuit/4650345819275264

Sure, but how is DC converted to AC in the first place? It's probably a pretty basic principle, I just haven't learned about it yet.

In general, an oscillator produces AC from DC. There are many forms of oscillator.

Interesting.
