Snobol4【1】 语言实战：HTML【2】 表格转 CSV【3】 文件实战
Snobol4 是一种古老的编程语言【4】，最初由美国贝尔实验室的David J. Farber等人于1962年设计。它以其简洁的语法和强大的字符串处理【5】能力而闻名。尽管在现代编程中Snobol4并不常见，但它在处理文本和字符串方面仍然有其独特的优势。本文将围绕Snobol4语言，通过一个实战案例——HTML表格转CSV文件，来展示Snobol4在文本处理方面的能力。
HTML表格转CSV文件背景
在Web开发【6】中，HTML表格是展示数据的一种常见方式。当需要将数据导入到其他应用程序或进行进一步处理时，将HTML表格转换为CSV（逗号分隔值）格式是一个常见的需求。CSV格式简单、易于阅读和编辑，是数据交换【7】的常用格式。
Snobol4 简介
Snobol4是一种高级编程语言，特别适合于文本处理。它具有以下特点：
- 简洁的语法：Snobol4的语法相对简单，易于学习和使用。
- 强大的字符串处理能力：Snobol4提供了丰富的字符串处理函数，可以轻松处理文本数据。
- 高效的运行速度：Snobol4的编译器【8】可以将源代码转换为高效的机器代码。
实战案例：HTML表格转CSV文件
1. HTML表格结构
我们需要一个HTML表格的示例：
html
姓名
年龄
职业
张三
30
程序员
李四
25
设计师
2. Snobol4代码实现
以下是一个使用Snobol4将上述HTML表格转换为CSV文件的示例代码：
```snobol
:INFILE 'input.html'
:OUTFILE 'output.csv'
