public static bool IsDescendantOf(this INode node, INode parent)

Checks if the node is an descendant of the given parent.

public static bool IsEndPoint(this INode node)

Checks if the provided node is an endpoint, i.e., does not host any other node.

public static bool IsEndPoint(this NodeType type)

Checks if the provided NodeType is an endpoint, i.e., does not host any other node.

public static bool IsFollowedByDoctype(this INode child)

Checks if the given child is followed by a document type.

public static bool IsFollowing(this INode after, INode before)
