Snobol4 语言 实战 Markdown 表格单元格提取实战

Snobol4^【1】 语言实战：Markdown 表格^【2】单元格^【4】提取实战

Snobol4 是一种古老的编程语言，最初由贝尔实验室在1962年开发，主要用于文本处理。尽管它已经不再流行，但Snobol4在文本处理领域仍有一定的应用价值。本文将围绕Snobol4语言，通过一个实战案例^【5】——Markdown表格单元格提取，来探讨Snobol4在文本处理中的实际应用。

Snobol4 简介

Snobol4 是 Snobol（StriNg Oriented and symBOlic Language）语言的第四个版本。它是一种高级编程语言，具有强大的字符串处理^【6】能力。Snobol4 的语法简洁，易于理解，特别适合于文本处理任务。

Snobol4 的主要特点包括：

- 强大的字符串处理能力
- 简洁的语法
- 高效的运行速度
- 支持正则表达式^【7】

Markdown 表格简介

Markdown 是一种轻量级标记语言，常用于格式化文本。Markdown 表格是一种简单的表格表示方法，通常用于展示数据。Markdown 表格的基本结构如下：


| 表头1 | 表头2 | 表头3 |
| --- | --- | --- |
| 单元格1 | 单元格2 | 单元格3 |
| 单元格4 | 单元格5 | 单元格6 |


实战案例：Markdown^【3】 表格单元格提取

在这个实战案例中，我们将使用 Snobol4 语言编写一个程序^【8】，用于从 Markdown 表格中提取单元格内容。

步骤 1：定义输入^【9】

我们需要定义一个包含 Markdown 表格的字符串。以下是一个示例：

markdown
| 表头1 | 表头2 | 表头3 |
| --- | --- | --- |
| 单元格1 | 单元格2 | 单元格3 |
| 单元格4 | 单元格5 | 单元格6 |


步骤 2：编写 Snobol4 程序

接下来，我们将编写一个 Snobol4 程序来提取表格中的单元格内容。以下是一个简单的 Snobol4 程序示例：
