I'm voting to close this question as off-topic because this site is not a debugging service.

comment Understanding a code for exploring XML tree
As for how the recursion is built-in, definitions such as f[x_, y_] := {f[x], f[y]}, for example, are clearly recursive and, therefore, induce recursion in the Mathematica kernel when f is called with two arguments. The kernel keeps evaluating an expression it is working on until it reaches a fixed-point.

comment Understanding a code for exploring XML tree
You should not write code with a structure you do not understand. That way lies madness. You should not just read the excellent tutorial on Transforming XML, you should work with its examples in your own Mathematica notebook. Then, perhaps, you will acquire enlightenment.

comment Evaluation speed of apparently equivalent functions
I would be surprised if [x_Integer] := x were not the fastest of the examples you give, for the simple reason that it requires the least effort to determine whether the actual argument passed matches the argument pattern.

comment Discrepancy in the series expansion of $\log(z/(z-1))$ in Mathematica 5
The OP's result is not local to V5. In V10.1 Series gives the same result.

comment How can I perfect this game for Wolfram Demonstration publication?
I'm voting to close this question as off-topic because it is too localized; i.e, it applies only to the local situation and needs of its poster and answers will not benefit others.
