Regex Ruby：解析一个简单的标记文件（具有相似但不相等的结构）并将内容填充到对象'；s属性,regex,ruby,parsing,markdown,Regex,Ruby,Parsing,Markdown,我有一个满是降价文件的文件夹。我想将它们中的每一个读入以下Ruby对象： File: h1: "This is the title" description: "This is some description.\n\nAnd even more description." content: "## This is an h2...etc. etc." File: h1: nil description: nil

我有一个满是降价文件的文件夹。我想将它们中的每一个读入以下Ruby对象：

File:
  h1: "This is the title"
  description: "This is some description.\n\nAnd even more description."
  content: "## This is an h2...etc. etc."

File:
  h1: nil
  description: nil
  content: "## This is an h2...More bla bla."

File:
  h1: "This is the title"
  description: nil
  content: "## This is an h2...Bla bla.

File:
  h1: nil
  description: This is a description...Some more description.
  content: "## This is an h2...Bla bla.

类文件
属性访问器：标题、描述、内容
结束

标记文件通常如下所示：

# This is the title

This is some description.

And even more description.

## This is an h2

Bla bla.

## This is another h2

More bla bla.

### This is even an h3

Again, more bla bla.

## Again, an h2

etc. etc.

这将导致以下Ruby对象：

File:
  h1: "This is the title"
  description: "This is some description.\n\nAnd even more description."
  content: "## This is an h2...etc. etc."

File:
  h1: nil
  description: nil
  content: "## This is an h2...More bla bla."

File:
  h1: "This is the title"
  description: nil
  content: "## This is an h2...Bla bla.

File:
  h1: nil
  description: This is a description...Some more description.
  content: "## This is an h2...Bla bla.

为了将文件的内容分配给Ruby对象的定义，我可以简单地使用一个正则表达式，它将提取

title

（第一个H1）、

description

（H1和下面的H2之间的文本）和

content

（所有其他内容）

但文件并不总是像这样：

# This is the title

This is some description.

And even more description.

## This is an h2

Bla bla.

## This is another h2

More bla bla.

### This is even an h3

Again, more bla bla.

## Again, an h2

etc. etc.

有时，没有H1
- （如果是，文件名将用于
```
标题
```
  ）
有时，没有描述
有时，没有内容

这些异常可以组合出现，即没有H1和说明的文件：

## This is an h2

Bla bla.

## This is another h2

More bla bla.

# This is the title

## This is an h2

Bla bla.

This is a description.

Some more description.

## This is an h2

Bla bla.

这将导致以下Ruby对象：

File:
  h1: "This is the title"
  description: "This is some description.\n\nAnd even more description."
  content: "## This is an h2...etc. etc."

File:
  h1: nil
  description: nil
  content: "## This is an h2...More bla bla."

File:
  h1: "This is the title"
  description: nil
  content: "## This is an h2...Bla bla.

File:
  h1: nil
  description: This is a description...Some more description.
  content: "## This is an h2...Bla bla.

或包含H1但没有说明的文件：

## This is an h2

Bla bla.

## This is another h2

More bla bla.

# This is the title

## This is an h2

Bla bla.

This is a description.

Some more description.

## This is an h2

Bla bla.

这将导致以下Ruby对象：

File:
  h1: "This is the title"
  description: "This is some description.\n\nAnd even more description."
  content: "## This is an h2...etc. etc."

File:
  h1: nil
  description: nil
  content: "## This is an h2...More bla bla."

File:
  h1: "This is the title"
  description: nil
  content: "## This is an h2...Bla bla.

File:
  h1: nil
  description: This is a description...Some more description.
  content: "## This is an h2...Bla bla.

或没有H1但有描述的文件：

## This is an h2

Bla bla.

## This is another h2

More bla bla.

# This is the title

## This is an h2

Bla bla.

This is a description.

Some more description.

## This is an h2

Bla bla.

这将导致以下Ruby对象：

File:
  h1: "This is the title"
  description: "This is some description.\n\nAnd even more description."
  content: "## This is an h2...etc. etc."

File:
  h1: nil
  description: nil
  content: "## This is an h2...More bla bla."

File:
  h1: "This is the title"
  description: nil
  content: "## This is an h2...Bla bla.

File:
  h1: nil
  description: This is a description...Some more description.
  content: "## This is an h2...Bla bla.

我想知道我是否可以使用一个奇特的正则表达式（我不是这方面的专家），或者我是否应该尝试以某种方式将其拆分为几个过程步骤。我在这里问了一个类似的问题：，但是除了上面描述的异常，我无法使用Ruby使正则表达式正常运行

任何解决这个问题的想法都是非常受欢迎的。多谢各位

PS：我还考虑过使用标记解析器解析标记，然后使用Nokogiri或其他允许我解析结果的东西。但对于这样一个基本上很简单的需求来说，这感觉开销太大了。

举个例子：

examples=[]
示例所有这些不同的示例都让我有点困惑，输入可能是什么样子的。这些示例的预期输出是什么？可能还想重新思考一下您的类名，我可以自由地在您的帖子中添加更多描述性细节：在每个示例之后，现在都有一个关于相应Ruby对象外观的描述。我真的不明白你想在do中实现什么。。。结束
block，但应该有类似于File.new的内容（h1:h1，description:description，content:content）
。也许你可以相应地修改代码？谢谢。哦，在我的回答中为你的问题添加了细节，你说得对，我应该把这些细节加入到问题中。我现在就移动它们。更新了答案以符合规格。亲爱的，我们现在非常接近了。我刚刚添加了另一个我忘记的例子：或者一个没有H1的文件，但是有一个描述。如果你能更新你的正则表达式，那么我想我们完成了！✅
