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
References the nth sibling after element[x], regardless of type. Compare with doc.element[x].+n.property, below.
Example

doc.td[0].b[0].@1.text

Bold 1
doc.td[0].b[0].@4.text
Null
doc.element[x].@-n.property
References the nth sibling prior to element[x], regardless of type. Compare with doc.element[x].-n.property, below.
