使用 Markdown 功能

本主题讨论如何使用 Aspose.Words 实现 Markdown 功能。 Markdown 是一种格式化纯文本的简单方法，可以轻松地将其转换为 HTML。 Aspose.Words 支持以下 Markdown 功能：

• 标题
• 块引用
• 水平规则
• 大胆强调
• 斜体强调

Markdown特征实现大多遵循Aspose.Words API中的CommonMark规范，所有特征都表示为相应的样式或直接格式化。意思就是

• 粗体和斜体表示为 Font.bold 和 Font.Italic。
• 标题是具有标题 1 - 标题 6 样式的段落。
• 引用是样式名称中带有"引用"的段落。
• HorizontalRule 是具有 HorizontalRule 形状的段落。

将 Markdown 转换为 Aspose.Words Document Object Model (DOM) 存在细微差别，如 将 Markdown 翻译为 Document Object Model (DOM) 文章中所述。

带强调的 Markdown 文档

本节向您演示如何生成 markdown 文档，重点如下：

Markdown treats asterisks (*) and underscores (_) as indicators of emphasis.
You can write **bold** or *italic* text. 
You can also write ***BoldItalic*** text.

以下代码片段可用于生成上面给出的 markdown 文档。

# For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-Python-via-.NET
doc = aw.Document()
builder = aw.DocumentBuilder(doc)

builder.writeln("Markdown treats asterisks (*) and underscores (_) as indicators of emphasis.")
builder.write("You can write ")

builder.font.bold = True
builder.write("bold")

builder.font.bold = False
builder.write(" or ")

builder.font.italic = True
builder.write("italic")

builder.font.italic = False
builder.writeln(" text. ")

builder.write("You can also write ")
builder.font.bold = True

builder.font.italic = True
builder.write("BoldItalic")

builder.font.bold = False
builder.font.italic = False
builder.write("text.")

builder.document.save(docs_base.artifacts_dir + "WorkingWithMarkdown.emphases.md")

带标题的 Markdown 文档

本节向您演示如何生成带有以下标题的 markdown 文档：

The following produces headings:
# Heading1
## Heading2
### Heading3
#### Heading4
##### Heading5
###### Heading6
# **Bold Heading1**

以下代码片段可用于生成上面给出的 markdown 文档。

# For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-Python-via-.NET
doc = aw.Document()
builder = aw.DocumentBuilder(doc)

# By default Heading styles in Word may have bold and italic formatting.
# If we do not want the text to be emphasized, set these properties explicitly to false.
builder.font.bold = False
builder.font.italic = False

builder.writeln("The following produces headings:")
builder.paragraph_format.style = doc.styles.get_by_name("Heading 1")
builder.writeln("Heading1")
builder.paragraph_format.style = doc.styles.get_by_name("Heading 2")
builder.writeln("Heading2")
builder.paragraph_format.style = doc.styles.get_by_name("Heading 3")
builder.writeln("Heading3")
builder.paragraph_format.style = doc.styles.get_by_name("Heading 4")
builder.writeln("Heading4")
builder.paragraph_format.style = doc.styles.get_by_name("Heading 5")
builder.writeln("Heading5")
builder.paragraph_format.style = doc.styles.get_by_name("Heading 6")
builder.writeln("Heading6")

# Note that the emphases are also allowed inside Headings.
builder.font.bold = True
builder.paragraph_format.style = doc.styles.get_by_name("Heading 1")
builder.writeln("Bold Heading1")

doc.save(docs_base.artifacts_dir + "WorkingWithMarkdown.headings.md")

带有大引号的 Markdown 文档

本节向您演示如何生成带有块引号的 markdown 文档，如下所示：

We support blockquotes in Markdown:
>*Lorem*
>*ipsum*
>The quotes can be of any level and can be nested:
>>>Quote level 3
>>>
>>>>Nested quote level 4
>
>*Back to first level*
>### Headings are allowed inside Quotes
>

以下代码片段可用于生成上面给出的 markdown 文档。

# For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-Python-via-.NET
doc = aw.Document()
builder = aw.DocumentBuilder(doc)

builder.writeln("We support blockquotes in Markdown:")
    
builder.paragraph_format.style = doc.styles.get_by_name("Quote")
builder.writeln("Lorem")
builder.writeln("ipsum")
    
builder.paragraph_format.style = doc.styles.get_by_name("Normal")
builder.writeln("The quotes can be of any level and can be nested:")
    
quoteLevel3 = doc.styles.add(aw.StyleType.PARAGRAPH, "Quote2")
builder.paragraph_format.style = quoteLevel3
builder.writeln("Quote level 3")
    
quoteLevel4 = doc.styles.add(aw.StyleType.PARAGRAPH, "Quote3")
builder.paragraph_format.style = quoteLevel4
builder.writeln("Nested quote level 4")
    
builder.paragraph_format.style = doc.styles.get_by_name("Quote")
builder.writeln()
builder.writeln("Back to first level")
    
quoteLevel1WithHeading = doc.styles.add(aw.StyleType.PARAGRAPH, "Quote Heading 3")
builder.paragraph_format.style = quoteLevel1WithHeading
builder.write("Headings are allowed inside Quotes")

doc.save(docs_base.artifacts_dir + "WorkingWithMarkdown.block_quotes.md")

带有水平线的 Markdown 文档

本节向您演示如何使用水平规则生成 markdown 文档，如下所示：

We support Horizontal rules (Thematic breaks) in Markdown:
-----

以下代码片段可用于生成上面给出的 markdown 文档。

# For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-Python-via-.NET
builder = aw.DocumentBuilder()

builder.writeln("We support Horizontal rules (Thematic breaks) in Markdown:")
builder.insert_horizontal_rule()

builder.document.save(docs_base.artifacts_dir + "WorkingWithMarkdown.horizontal_rule_example.md")

阅读 Markdown 文档

以下代码片段向您展示了如何阅读 markdown 文档。

# For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-Python-via-.NET
doc = aw.Document(docs_base.my_dir + "Quotes.md")

# Let's remove Heading formatting from a Quote in the very last paragraph.
paragraph = doc.first_section.body.last_paragraph
paragraph.paragraph_format.style = doc.styles.get_by_name("Quote")

doc.save(docs_base.artifacts_dir + "WorkingWithMarkdown.read_markdown_document.md")

指定 Markdown 保存选项

Aspose.Words API 提供 MarkdownSaveOptions 类来在将文档保存为 Markdown 格式时指定附加选项。

以下代码示例演示了如何指定各种 Markdown 保存选项。

# For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-Python-via-.NET
doc = aw.Document()
builder = aw.DocumentBuilder(doc)

builder.writeln("Some text!")

doc.save(docs_base.artifacts_dir + "BaseConversions.docx_to_markdown.md")

导出到 Markdown 时如何对齐表格内的内容

Aspose.Words API 提供 TableContentAlignment 枚举，它定义对齐方向，以便在导出到 Markdown 文档时对齐表格中的内容。以下代码示例演示如何对齐表格内的内容。

# For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-Python-via-.NET
doc = aw.Document()
builder = aw.DocumentBuilder(doc)

builder.insert_cell()
builder.paragraph_format.alignment = aw.ParagraphAlignment.RIGHT
builder.write("Cell1")
builder.insert_cell()
builder.paragraph_format.alignment = aw.ParagraphAlignment.CENTER
builder.write("Cell2")

# Makes all paragraphs inside the table to be aligned.
saveOptions = aw.saving.MarkdownSaveOptions()
    
saveOptions.table_content_alignment = aw.saving.TableContentAlignment.LEFT
    
doc.save(docs_base.artifacts_dir + "WorkingWithMarkdownSaveOptions.left_table_content_alignment.md", saveOptions)

saveOptions.table_content_alignment = aw.saving.TableContentAlignment.RIGHT
doc.save(docs_base.artifacts_dir + "WorkingWithMarkdownSaveOptions.right_table_content_alignment.md", saveOptions)

saveOptions.table_content_alignment = aw.saving.TableContentAlignment.CENTER
doc.save(docs_base.artifacts_dir + "WorkingWithMarkdownSaveOptions.center_table_content_alignment.md", saveOptions)

# The alignment in this case will be taken from the first paragraph in corresponding table column.
saveOptions.table_content_alignment = aw.saving.TableContentAlignment.AUTO
doc.save(docs_base.artifacts_dir + "WorkingWithMarkdownSaveOptions.auto_table_content_alignment.md", saveOptions)
