Extraction Anchor

With extraction anchor we mean that part of the extraction command that is used to find the information to extract. Since the information is always inside a HTML element, the extraction anchor defines this HTML somehow.

Example:

If we have this web element:

   <span class="price">US$ 899.00</span>

Assume we want to extract the price. So in this case the bold part is the extraction anchor. It never changes, even if the information (here: US$ 899) changes.
