| 元素定位 | Element.getElementsByClass(String className) | 根据 class 属性获取子元素集合，等价于select(".className") |
| 文本处理 | Element.text() | 获取元素内的纯文本内容（剔除所有 HTML 标签），包含所有子元素的文本 |
| 文本处理 | Element.ownText() | 仅获取当前元素自身的纯文本（不包含子元素的文本） |
| 文本处理 | Element.text(String text) | 设置元素的纯文本内容（覆盖原有内容，自动转义特殊字符如 <、>） |
| HTML 处理 | Element.html() | 获取元素内的 HTML 内容（包含子元素的标签） |
| HTML 处理 | Element.html(String html) | 设置元素的 HTML 内容（覆盖原有内容，不转义标签，直接渲染） |
| HTML 处理 | Element.outerHtml() | 获取当前元素及其内部所有内容的完整 HTML（包含自身标签） |
| 属性操作 | Element.attr(String key) | 获取元素指定属性的值，如attr("href")获取链接地址 |
| 属性操作 | Element.attr(String key, String value) | 设置元素指定属性的值，如attr("src", "new.jpg") |
| 属性操作 | Element.hasAttr(String key) | 判断元素是否包含指定属性（返回 boolean） |
| 属性操作 | Element.removeAttr(String key) | 移除元素的指定属性 |
| 元素遍历 | Element.parent() | 获取当前元素的父元素 |
| 元素遍历 | Element.children() | 获取当前元素的所有直接子元素（返回 Elements） |
| 元素遍历 | Element.siblingElements() | 获取当前元素的所有同级元素（排除自身） |
| 元素遍历 | Element.nextElementSibling() | 获取当前元素的下一个同级元素 |
| 元素遍历 | Element.previousElementSibling() | 获取当前元素的上一个同级元素 |
| 表单处理 | Element.val() | 获取表单元素（input/select/textarea）的 value 值 |
| 表单处理 | Element.val(String value) | 设置表单元素的 value 值 |
| 文档信息 | Document.title() | 获取 HTML 文档的标签内容</td></tr><tr><td align="left">文档信息</td><td align="center">Document.title(String title)</td><td align="left">设置 HTML 文档的<title>标签内容</td></tr><tr><td align="left">输出格式化</td><td align="center">Document.outputSettings()</td><td align="left">获取输出设置对象，可配置 HTML 缩进、字符编码、是否格式化等</td></tr><tr><td align="left">输出格式化</td><td align="center">Element.toString()</td><td align="left">将元素转换为格式化后的 HTML 字符串</td></tr></tbody></table> </article>
