Relative boundary selector

Overview​

This auxiliary selector cannot be used as a standalone selector, or as the first step of the parsing pipeline.

It restricts the area on the page where the data to be extracted is located. Unlike the Boundary selector, the restriction will be applied depending on the objects returned by the preceding selector.

For instance, if the Relative boundary selector is added after the Boundary selector to extract the value: $624
