pub fn set_attr(&mut self, key: &str, val: &str)
pub fn remove_attr(&mut self, key: &str)
Sourcepub fn remove_id(&mut self)
pub fn remove_id(&mut self)
Convenience: remove the id attribute (safe wrapper for tests parity with JS removeAttribute(‘id’))
Sourcepub fn set_id(&mut self, id: &str)
pub fn set_id(&mut self, id: &str)
Convenience: set id attribute (safe wrapper to avoid direct raw mutation in tests)
pub fn attributes(&mut self) -> HashMap<String, String>
pub fn raw_attributes(&mut self) -> HashMap<String, String>
Sourcepub fn raw_attrs_str(&self) -> &str
pub fn raw_attrs_str(&self) -> &str

Sourcepub fn insert_adjacent_html(
&mut self,
position: &str,
html: &str,
) -> Result<(), String>
pub fn insert_adjacent_html( &mut self, position: &str, html: &str, ) -> Result<(), String>
解析片段为节点列表（不包裹额外 root），使用默认 Options insertAdjacentHTML(position, html) 支持: beforebegin | afterbegin | beforeend | afterend beforebegin/afterend 会插入到父节点 children 中（若无父则忽略）
Sourcepub fn replace_with(&mut self, html_fragment: &str)
pub fn replace_with(&mut self, html_fragment: &str)
replaceWith(html_fragment) 用片段替换自身
pub fn replace_with_items(&mut self, items: &[NodeOrStr<'_>])
pub fn text(&self) -> String
Sourcepub fn inner_text(&self) -> String
pub fn inner_text(&self) -> String
对应 JS innerText: 返回未解码聚合文本 (即 rawText)
Sourcepub fn text_content(&self) -> String
pub fn text_content(&self) -> String
对应 JS textContent getter: 返回解码后的文本
Sourcepub fn set_text_content(&mut self, val: &str)
pub fn set_text_content(&mut self, val: &str)
对应 JS textContent setter: 先对传入进行实体编码，再替换子节点为单一文本节点

Sourcepub fn set_content(&mut self, content: &str)
pub fn set_content(&mut self, content: &str)

pub fn new( tag: Option<String>, raw_attrs: String, attrs: Vec<(String, String)>, is_void: bool, void_add_slash: bool, ) -> Self
pub fn is_root(&self) -> bool
pub fn name(&self) -> &str
Sourcepub fn set_tag_name(&mut self, new_name: &str)
pub fn set_tag_name(&mut self, new_name: &str)
JS HTMLElement.tagName setter 行为：赋值后序列化使用小写（JS 内部存 rawTagName 小写，tagName getter 返回大写）。 为贴近 JS，我们内部沿用小写存储，外部序列化 already 调用 self.name()（即原样）。

&'a self,
root: &'a HTMLElement,
selector: &str,
) -> bool
pub fn matches_selector<'a>( &'a self, root: &'a HTMLElement, selector: &str, ) -> bool

pub fn remove_whitespace(&mut self)
Sourcepub fn trim_right(&mut self, pattern: &Regex)
pub fn trim_right(&mut self, pattern: &Regex)
模拟 JS HTMLElement.trimRight(pattern): 从右侧开始找到第一个匹配 TextNode 截断后续节点。

pub fn get_element_by_id<'a>(&'a self, id: &str) -> Option<&'a HTMLElement>
pub fn get_element_by_id_mut<'a>( &'a mut self, id: &str, ) -> Option<&'a mut HTMLElement>

pub fn clone_shallow(&self) -> HTMLElement
浅拷贝（不包含子节点）

JS appendChild(TextNode) 等价：直接加入文本节点

Sourcepub fn set_content_node(&mut self, node: Node)
