trait ClarkElemApi[E <: ClarkElemApi[E]] extends ElemApi[E] with IsNavigableApi[E] with HasENameApi with HasTextApi

Shorthand for ElemApi[E] with IsNavigableApi[E] with HasENameApi with HasTextApi. In other words, the minimal element query API corresponding to James Clark's "labelled element tree" abstraction, which is implemented as yaidom "resolved" elements.

If a yaidom element implementation (whether in yaidom itself or a "yaidom extension") does not mix in the ClarkElemApi trait, it is probably not to be considered "XML". Indeed, in yaidom only the ElemBuilder class does not mix in this trait, and indeed it is not "XML" (lacking any knowledge about expanded names etc.), only a builder of "XML". Hence this trait is very important in yaidom, as the "minimal XML element query API".

Generic code abstracting over yaidom element implementations should either use this trait, or sub-trait ScopedElemApi, depending on the abstraction level.

    Finds the element with the given Path (where this element is the root), if any, wrapped in an Option.

    That is, returns:

    findReverseAncestryOrSelfByPath(path).map(_.last)

    Note that for each non-empty Path, we have:

    Finds the reversed ancestry-or-self of the element with the given Path (where this element is the root), wrapped in an Option.

    Finds the reversed ancestry-or-self of the element with the given Path (where this element is the root), wrapped in an Option. None is returned if no element can be found at the given Path.

    Hence, the resulting element collection, if any, starts with this element and ends with the element at the given Path, relative to this element.

    This method comes in handy for (efficiently) computing base URIs, where the (reverse) ancestry-or-self is needed as input.
