CNSA Article Extractor

Extracts full article content from the China National Space Administration (CNSA) website at www.cnsa.gov.cn.

Overview

The CNSA website uses a specific HTML structure for news articles that generic extractors often fail to parse correctly. This skill handles the specific page structure with classes like:

• .wz_title - Article title
• .wz_rq - Publish date (发布时间)
• .wz_ly - Source (来源)
• .wz_conten - Main article content

Functions

fetch_article

Fetches and parses a single CNSA news article.

Parameters:

• url (required): Full URL to the CNSA article page

Returns:

{
  "url": "https://www.cnsa.gov.cn/n6758823/n6758838/c10726362/content.html",
  "title": "神舟二十号飞船安全顺利返回东风着陆场",
  "publish_date": "2026-01-19",
  "source": "中国载人航天工程网",
  "content": "北京时间2026年1月19日9时34分，神舟二十号飞船返回舱在东风着陆场成功着陆...",
  "keywords": "国家航天局",
  "description": null
}

Error Responses:

• NOT_FOUND: Article page returns 404
• HTTP_ERROR: Failed to fetch page (includes status code)
• TIMEOUT: Request timed out
• REQUEST_ERROR: Network or connection error
• PARSE_ERROR: Failed to parse HTML content
• MISSING_PARAM: Required URL parameter missing
• INVALID_URL: URL format invalid

Example Usage

result = await execute({
    'function': 'fetch_article',
    'url': 'https://www.cnsa.gov.cn/n6758823/n6758838/c10726362/content.html'
})

if 'error' not in result:
    print(f"Title: {result['title']}")
    print(f"Date: {result['publish_date']}")
    print(f"Source: {result['source']}")
    print(f"Content: {result['content'][:200]}...")

Technical Details

• Uses httpx for HTTP requests with browser-like headers
• Parses HTML with BeautifulSoup4
• Extracts content from paragraphs styled with text-indent for proper formatting
• Deduplicates paragraph content
• Removes UI elements (font size controls, print buttons)
• Returns clean, structured article data

Content Structure Notes

CNSA articles typically follow this structure:

<div class="wz">
  <div class="wz_title">Article Title</div>
  <div class="wz_rqly">
    <span class="wz_rq">发布时间：2026-01-19</span>
    <span class="wz_ly">来源：Source Name</span>
  </div>
  <div class="wz_conten">
    <!-- Paragraphs with text-indent style -->
    <div style="text-indent: 2em; ...">First paragraph...</div>
    <div style="text-indent: 2em; ...">Second paragraph...</div>
  </div>
</div>

The extractor handles this specific structure to reliably extract all article components.
