org.seimicrawler.xpath.core.axis中AxisSelector的使用

实现AxisSelector的org.seimicrawler.xpath.core.axis中的类

限定符和类型	类和说明
class	AncestorOrSelfSelector the ancestor-or-self axis contains the context node and the ancestors of the context node; thus, the ancestor axis will always include the root node
class	AncestorSelector the ancestor axis contains the ancestors of the context node; the ancestors of the context node consist of the parent of context node and the parent's parent and so on; thus, the ancestor axis will always include the root node, unless the context node is the root node
class	AttributeSelector the attribute axis contains the attributes of the context node; the axis will be empty unless the context node is an element
class	ChildSelector the child axis contains the children of the context node
class	DescendantOrSelfSelector the descendant-or-self axis contains the context node and the descendants of the context node
class	DescendantSelector the descendant axis contains the descendants of the context node; a descendant is a child or a child of a child and so on; thus the descendant axis never contains attribute or namespace nodes
class	FollowingSelector the following axis contains all nodes in the same document as the context node that are after the context node in document order, excluding any descendants and excluding attribute nodes and namespace nodes
class	FollowingSiblingOneSelector the following-sibling-one JsoupXpath自定义扩展,比较常用
class	FollowingSiblingSelector the following-sibling axis contains all the following siblings of the context node; if the context node is an attribute node or namespace node, the following-sibling axis is empty
class	ParentSelector the parent axis contains the parent of the context node, if there is one https://www.w3.org/TR/1999/REC-xpath-19991116/#NT-AxisSpecifier
class	PrecedingSelector the preceding axis contains all nodes in the same document as the context node that are before the context node in document order, excluding any ancestors and excluding attribute nodes and namespace nodes
class	PrecedingSiblingOneSelector the preceding-sibling-one axis JsoupXpath自定义扩展，用于选取节点的前一个兄弟节点，如果存在的话。
class	PrecedingSiblingSelector the preceding-sibling axis contains all the preceding siblings of the context node; if the context node is an attribute node or namespace node, the preceding-sibling axis is empty
class	SelfSelector the self axis contains just the context node itself
