## 在列表页面点击 Listly 后选择 **深层提取（Deep Extract）**

在连往详情页面的列表页面中，点击已[安装的 Listly 扩展程序](https://help.listly.io/docs/zh-hans/~/revisions/RHoapisHoSFsPP2DNX4c/getting-started/quick-start-guide/how-to-install-listly)图标。在 Listly 扩展程序中选择 **\[深层提取（Deep Extract）]**。

{% endstep %}

{% step %}

## 收集详情页面网址

选择列表页面中的项目。点击具有相同模式的网址区域时，会出现可自动选择整个该区域的弹出窗口。

* 若想提取的详情页面具有相同模式，请点击 **\[一并选择（Select together）]**。大多数情况下，点击此选项即可一次自动选择所有详情页面。
* 若想提取的区域是不具相同模式的个别独立详情页面，请点击 **\[否（仅此项）]** 按钮。

{% endstep %}

{% step %}

## 选择详情页面打开的间隔

在选择提取区域之前，可以设置访问各个详情页面的间隔。若网页内信息较多，或网络连接不稳定，请将网页访问间隔设置得比默认值 0.5 秒稍长一些。

{% endstep %}

{% step %}

## 选择详情页面区域

收集的网址中第一个详情页面打开后，请在页面中选择想提取的区域。与[部分提取（Extract Part）](https://help.listly.io/docs/zh-hans/~/revisions/RHoapisHoSFsPP2DNX4c/getting-started/extension-features/parts)功能相同，只要用鼠标点击想要的区域即可提取。

选择完所有提取区域后，点击 **\[开始提取]** 按钮。

{% endstep %}

{% step %}

## 确认结果后下载

在结果画面向下滚动，确认收集到您所选数据的标签页。

❶ 像深层提取这样一次提取多个页面时，各页面的提取结果会放在同一个文件夹中。若想将多个页面的数据汇总成单一工作表，该区域必须设置为 **\[整个文件夹（Whole folder）]**。

❷ 通过 **Data Layout** 选项，可以预览数据在 Excel 文件中的排列方式。选择合适的布局后，点击 **\[Excel]** 或 **\[Google Sheets]** 按钮导出数据。

<figure><img src="https://5118966-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FLlkvcuviCyyU871Augk5%2Fuploads%2FLwMXolJLg53HI6b7c7VN%2Fimage.png?alt=media&amp;token=8a334d55-c802-4f6b-a9cd-b770d99e7f7a" alt=""><figcaption></figcaption></figure>

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.listly.io/docs/zh-hans/getting-started/extension-features/shen-ceng-ti-qu-deep-extract.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
