traverse to the element label

traverse to the element label

Attributes

def label(value: String): Iterator[E]

filter by the element label Note: do not use as the first step in a traversal, e.g. traversalSource.all.label(value). Use traversalSource.label instead, it is much faster TODO: make the above an automatic optimisation
