comparePoint method
The Range.comparePoint() method returns -1,
0, or 1 depending on whether the referenceNode is
before, the same as, or after the Range.
If the reference node is a Node of type Text,
Comment, or CDATASection, then offset is the number of
characters from the start of reference node. For other Node
types, offset is the number of child nodes between the start of the
reference
node.
Implementation
external int comparePoint(
Node node,
int offset,
);
