Yeah maybe not the best idea, XPath has a pretty different use case than CSS. But it does seem a shame that more complex "nth-child" selectors do not just use something more flexible/programmable like xpath. As it stands CSS keeps adding one-off selectors such as nth-child, only-child, only-of-type. Such is the feature creep of web standards as they are, a continual addition of one-off APIs for specific use cases rather than a robust orthogonal programming platform that people can build anything on top of, like WebCrypto instead of adding integers.
