Understanding HTML Markdown Conversion Fundamentals

Basic Conversion Principles

**Core **HTML markdown** conversion concepts:**

### **Structural Element Mapping**

**HTML Headers → Markdown Headers**
```html
<!-- HTML Input -->
<h1>Main Title</h1>
<h2>Section Header</h2>
<h3>Subsection Header</h3>

<!-- Markdown Output -->
# Main Title
## Section Header  
### Subsection Header

HTML Paragraphs → Markdown Paragraphs

<!-- HTML Input -->
<p>This is a paragraph with <strong>bold text</strong> 
and <em>italic text</em> formatting.</p>

<!-- Markdown Output -->
This is a paragraph with **bold text** and *italic text* formatting.

HTML Lists → Markdown Lists

<!-- HTML Input -->
<ul>
  <li>First unordered item</li>
  <li>Second unordered item</li>
</ul>

<ol>
  <li>First ordered item</li>
  <li>Second ordered item</li>
</ol>

<!-- Markdown Output -->
- First unordered item
- Second unordered item

1. First ordered item
2. Second ordered item

### Advanced Conversion Scenarios
```markdown
**Complex **HTML markdown** conversion examples:**

### **Table Conversion**

**HTML Tables → Markdown Tables**
```html
<!-- HTML Input -->
<table>
  <thead>
    <tr>
      <th>Feature</th>
      <th>HTML</th>
      <th>Markdown</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Simplicity</td>
      <td>Complex</td>
      <td>Simple</td>
    </tr>
    <tr>
      <td>Readability</td>
      <td>Verbose</td>
      <td>Clean</td>
    </tr>
  </tbody>
</table>

<!-- Markdown Output -->
| Feature | HTML | Markdown |
|---------|------|----------|
| Simplicity | Complex | Simple |
| Readability | Verbose | Clean |

Code Block Conversion

HTML Code → Markdown Code Blocks

<!-- HTML Input -->
<pre><code class="language-javascript">
function convertHtmlToMarkdown(html) {
  return html.replace(/<h1>(.*?)<\/h1>/g, '# $1');
}
</code></pre>

<!-- Markdown Output -->
```javascript
function convertHtmlToMarkdown(html) {
  return html.replace(/<h1>(.*?)<\/h1>/g, '# $1');
}

### **Link and Image Conversion**

**HTML Links/Images → Markdown Format**
```html
<!-- HTML Input -->
<a href="https://example.com" title="Example Site">Visit Example</a>
<img src="image.jpg" alt="Description" title="Image Title">

<!-- Markdown Output -->
[Visit Example](https://example.com "Example Site")
![Description](image.jpg "Image Title")

## Platform-Specific Conversion Strategies

### WordPress to Markdown Migration
```markdown
**WordPress **HTML markdown** migration workflow:**

### **Content Export and Preparation**

**WordPress Export Process**
1. **Export WordPress content** using WP Admin → Tools → Export
2. **Parse XML export file** to extract post content
3. **Clean HTML content** removing WordPress-specific elements
4. **Convert to markdown** using automated tools
5. **Validate output** and fix conversion issues

**WordPress-Specific Conversion Script**
```php
<?php
// WordPress HTML markdown conversion script
function convert_wp_post_to_markdown($post_content) {
    // Remove WordPress shortcodes
    $content = strip_shortcodes($post_content);
    
    // Convert WordPress HTML to clean HTML
    $content = wp_kses($content, array(
        'h1' => array(), 'h2' => array(), 'h3' => array(),
        'p' => array(), 'strong' => array(), 'em' => array(),
        'ul' => array(), 'ol' => array(), 'li' => array(),
        'a' => array('href' => array(), 'title' => array()),
        'img' => array('src' => array(), 'alt' => array())
    ));
    
    // Use Pandoc for final conversion
    $temp_file = tempnam(sys_get_temp_dir(), 'wp_content');
    file_put_contents($temp_file, $content);
    
    $markdown = shell_exec("pandoc $temp_file -t gfm");
    unlink($temp_file);
    
    return $markdown;
}

// Process all posts
$posts = get_posts(array('numberposts' => -1));
foreach ($posts as $post) {
    $markdown = convert_wp_post_to_markdown($post->post_content);
    // Save markdown file
    file_put_contents("posts/{$post->post_name}.md", $markdown);
}
?>

Image and Media Handling

Media Migration Strategy

• Download images from WordPress media library
• Update image paths in converted markdown
• Optimize image formats for static site deployment
• Implement responsive images where applicable

# Download WordPress images
wget -r -np -nH --cut-dirs=3 -A jpg,jpeg,png,gif \
     https://yoursite.com/wp-content/uploads/

# Update image paths in markdown files
find . -name "*.md" -exec sed -i \
     's|https://yoursite.com/wp-content/uploads/|/images/|g' {} \;

### GitHub Wiki to Markdown
```markdown
**GitHub Wiki **HTML markdown** conversion:**

### **Wiki Content Migration**

**GitHub Wiki Cloning and Conversion**
```bash
# Clone GitHub wiki repository
git clone https://github.com/user/repo.wiki.git

# Convert wiki files to standard markdown
for file in *.md; do
    # Convert GitHub wiki syntax to standard markdown
    sed -i 's/\[\[([^|]*)\|\([^]]*\)\]\]/[\2](\1)/g' "$file"
    
    # Fix internal linking
    sed -i 's/\.md)/)\/)/g' "$file"
done

Wiki-Specific Conversion Considerations

• Internal linking: Convert wiki-style links to markdown
• Page hierarchy: Maintain navigation structure
• Sidebar content: Transform to index or navigation files
• Special pages: Convert _Sidebar, _Footer to appropriate formats

Advanced Wiki Processing

# GitHub wiki to markdown converter
import re
import os
from pathlib import Path

class WikiToMarkdownConverter:
    def __init__(self):
        self.wiki_link_pattern = r'\[\[([^|\]]+)(?:\|([^\]]+))?\]\]'
        
    def convert_wiki_links(self, content):
        """Convert [[Page|Title]] to [Title](Page)"""
        def replace_link(match):
            page = match.group(1)
            title = match.group(2) or page
            return f"[{title}]({page.replace(' ', '-').lower()})"
        
        return re.sub(self.wiki_link_pattern, replace_link, content)
    
    def process_wiki_file(self, input_path, output_path):
        """Process single wiki file"""
        with open(input_path, 'r', encoding='utf-8') as f:
            content = f.read()
        
        # Convert wiki-specific syntax
        content = self.convert_wiki_links(content)
        
        # Add frontmatter for static site generators
        title = Path(input_path).stem.replace('-', ' ').title()
        frontmatter = f"""---
title: "{title}"
---

"""
        content = frontmatter + content
        
        with open(output_path, 'w', encoding='utf-8') as f:
            f.write(content)

# Convert entire wiki
converter = WikiToMarkdownConverter()
for wiki_file in Path('./wiki').glob('*.md'):
    output_file = Path('./docs') / wiki_file.name
    converter.process_wiki_file(wiki_file, output_file)

**Essential **HTML markdown** conversion best practices:**

### **Pre-Conversion Planning**

1. **Content Audit and Classification**
   - **Inventory all content** types and structures
   - **Identify complex elements** requiring special handling
   - **Map conversion priorities** based on content importance
   - **Document custom HTML** elements and their markdown equivalents

2. **Backup and Version Control**
   - **Create complete backups** of original HTML content
   - **Establish Git repository** for conversion tracking
   - **Tag conversion milestones** for rollback capability
   - **Document conversion decisions** for team reference

3. **Tool Selection and Configuration**
   - **Evaluate conversion tools** for specific content types
   - **Configure conversion rules** for consistent output
   - **Test conversion quality** on sample content
   - **Establish validation criteria** for conversion success

### **During Conversion Execution**

1. **Systematic Processing**
   - **Process content in batches** for quality control
   - **Maintain conversion logs** for tracking progress
   - **Validate each batch** before proceeding to next
   - **Handle edge cases** with documented procedures

2. **Quality Assurance**
   - **Compare before/after** content for accuracy
   - **Test internal links** and navigation structures
   - **Verify media files** and references
   - **Check special formatting** and code blocks

3. **Issue Tracking**
   - **Document conversion problems** and solutions
   - **Maintain issue tracker** for systematic resolution
   - **Create conversion reports** for stakeholder review
   - **Establish escalation procedures** for complex issues

**Automated **HTML markdown** conversion workflows:**

### **Custom Conversion Scripts**

**Advanced Pandoc Configuration**
```bash
#!/bin/bash
# Advanced HTML to Markdown conversion script

# Configuration
INPUT_DIR="./html_content"
OUTPUT_DIR="./markdown_content"
TEMP_DIR="./temp_conversion"

# Create directories
mkdir -p "$OUTPUT_DIR" "$TEMP_DIR"

# Process each HTML file
find "$INPUT_DIR" -name "*.html" | while read -r file; do
    echo "Processing: $file"
    
    # Extract filename without extension
    basename=$(basename "$file" .html)
    
    # Pre-process HTML
    python3 scripts/preprocess_html.py "$file" "$TEMP_DIR/$basename.html"
    
    # Convert with Pandoc
    pandoc "$TEMP_DIR/$basename.html" \
        --from html \
        --to gfm \
        --wrap=none \
        --extract-media="$OUTPUT_DIR/images" \
        --output "$OUTPUT_DIR/$basename.md"
    
    # Post-process markdown
    python3 scripts/postprocess_markdown.py "$OUTPUT_DIR/$basename.md"
    
    echo "Completed: $basename.md"
done

# Cleanup
rm -rf "$TEMP_DIR"
echo "Conversion complete!"
