创建新文档类型页面，包含名称字段、“Table available”复选框、描述字段以及“Auto”和“Regex”按钮 — 选择“Regex”，以使用正则表达式对新的文档类型进行分类。

## **添加和移除正则表达式** “Regex”步骤会显示已有的正则表达式模型，每个模型都列出来源和模式，并提供用于创建新正则表达式模型的“Add”按钮。使用每行末尾的操作菜单来管理对应条目。点击“Next”继续配置“Fields & groups”。

Regex 步骤，包含“Add”按钮以及一张列出三个正则表达式模型、来源、模式和操作的表格 — 已有的正则表达式模型及其来源和模式。点击“Add”可创建新模型。

--- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.docbits.com/chinese/guan-li-yu-she-zhi/setup/document-types/regex-manager.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
