Sibling Operators
WQL provides the following set of operators to refer to siblings of a specified element. The examples shown in these descriptions refer to the following HTML structure:
The sibling operators are constrained by the current parent. If an operator exceeds the boundaries of the current parent, a null value is produced for that reference.
doc.element[x].@n.property
