Struct NodeRef 

pub struct NodeRef<'a> { /* private fields */ }

节点的引用。可以复制，比较时比的是节点身份。

Implementations

impl<'a> NodeRef<'a>

pub fn id(&self) -> NodeId

pub fn document(&self) -> &'a Html<'a>

pub fn parent(&self) -> Option<NodeRef<'a>>

pub fn first_child(&self) -> Option<NodeRef<'a>>

pub fn last_child(&self) -> Option<NodeRef<'a>>

pub fn next_sibling(&self) -> Option<NodeRef<'a>>

pub fn prev_sibling(&self) -> Option<NodeRef<'a>>

pub fn children(&self) -> Children<'a>

pub fn descendants(&self) -> Descendants<'a>

自身加所有后代，先序（文档顺序）。

pub fn ancestors(&self) -> Ancestors<'a>

父节点、祖父节点……直到根，不含自身。

后代（不含自身）里匹配选择器的元素，按文档顺序；:scope 匹配自身。

impl NodeRef<'_>

pub fn html(&self) -> String

节点自身及其子树的 HTML（元素的 outer HTML）。

pub fn inner_html(&self) -> String

子节点的 HTML（元素的 inner HTML）。
