Html 我想解析SEC文件并创建类别或每个'；项目'/文本部分。我该如何考虑这样做？,html,regex,node.js,parsing,Html,Regex,Node.js,Parsing,我假设我有一个所需SEC文件的数据库（最初是表格10s）。大多数文件都是HTML标签；它们看起来像这样： <DOCUMENT> <TYPE>10-K <SEQUENCE>1 <FILENAME>d445434d10k.htm <DESCRIPTION>FORM 10-K <TEXT> <HTML><HEAD> <TITLE>Form 10-K</TITLE> </HEAD

我假设我有一个所需SEC文件的数据库（最初是表格10s）。大多数文件都是HTML标签；它们看起来像这样：

…并且能够将每个部分调用到自定义视图中（制作自定义和压缩版本；只说项目1.业务和细分信息），摆脱样板文件。我的模型将具有此文档中的类型、文件名和某些其他元数据

您将如何通过解析来以我想要的方式存储文档？根据段落的主题，将每个段落存储在一个单独的部分将是非常棒的

最后，它们中的大多数并不完全相同，但有许多共同之处。最后，这个问题不是关于XBRL或任何定量数据/表格，纯文本。我用NodeJS来做这个

感谢您的帮助

你在哪里被代码卡住了？如果它不是格式良好的HTML（XHTML），解析将是“有趣的”。Gluckle我已经花了数百个工时解析、提取和解释来自EDGAR的数据，可以向您保证，这不是一项简单的任务。10-K，K/A和10-Q，Q/A文件实际上是围绕自动生成的HTML的SGML包装。正则表达式是（或应该是）你在这类工作中最好的朋友。对于解析/识别/提取公司名称、日期、位置等信息，你需要阅读“命名实体识别”，如果你打算识别/分类业务之间的关系，你需要进行研究“词性标记”以及RDF等知识表示框架。除了@RobRaisch建议的正则表达式（或与之结合），您还可以使用like和贝叶斯逻辑。
