主要观点总结
这是一个关于吉林新闻联播的内容摘要提取的示例。该代码通过JavaScript实现，包含对页面元素的描述、关键词高亮、内容格式化等功能。它首先通过检查网页上的元素，提取与特定关键词相关的信息，并对其进行高亮显示。同时，也处理了与网页内容相关的描述信息，并根据不同的页面类型（如视频、文本、图片等）进行不同的处理。最后，这些信息被组织成JSON格式，可用于后续的报告或数据分析。
关键观点总结
关键观点1: 关键词提取与高亮
通过JavaScript代码，提取与特定关键词相关的信息，并对其进行高亮显示。
关键观点2: 内容格式化
根据页面类型（视频、文本、图片等）对内容进行格式化，以适应不同的展示需求。
关键观点3: JSON格式输出
将提取的信息组织成JSON格式，便于后续的数据处理和分析。
