    (Hey, is dead.)

    Do you have any benchmarks for your XPath implementation?

    At the moment, not so good. The style of the compiled code is “good for optimizer”, but the optimizator isn’t written (yet).

    The worst, unhonest case. Generative XPath on top of a few layers vs native libxml2 XPath: 30 times slower.

    Bad case: “//a[b]” vs manually written (a variant of this): 20 times slower.

    Normal: vs SXPath: 2 times slower.

    But I expect that after even trivial optimizations, I’ll beat libxml2.

    Under construction.
