CNKI Parse Search Results

RC browser tool: navigate with browser action=open url="..."; run the JS in each step via browser action=act kind=evaluate fn="<the async function shown>" (the whole function body goes into fn). Never pass a profile — RC uses its default managed Chrome (CDP 18800).

Extract structured paper data from the current CNKI search results page.

Prerequisites

The current Chrome page must be a CNKI search results page (URL contains kns.cnki.net and page shows "条结果").

Steps

1. Verify we are on a results page

Use browser action=snapshot mode=efficient. Verify the page contains "条结果". If not, inform the user that no search results page is currently open.

Check for captcha ("拖动下方拼图完成验证") - if found, notify user to solve it manually.

2. Extract results via JavaScript

Use browser action=act kind=evaluate with this function:

() => {
  const rows = document.querySelectorAll('.result-table-list tbody tr');
  const checkboxes = document.querySelectorAll('.result-table-list tbody input.cbItem');
  const results = Array.from(rows).map((row, index) => {
    const nameCell = row.querySelector('td.name');
    const titleLink = nameCell?.querySelector('a.fz14');
    const authorCell = row.querySelector('td.author');
    const sourceCell = row.querySelector('td.source');
    const dateCell = row.querySelector('td.date');
    const dataCell = row.querySelector('td.data');
    const quoteCell = row.querySelector('td.quote');
    const downloadCell = row.querySelector('td.download');
    const isOnlineFirst = !!nameCell?.querySelector('.marktip');

    return {
      number: index + 1,
      title: titleLink?.innerText?.trim() || '',
      url: titleLink?.href || '',
      exportId: checkboxes[index]?.value || '',
      authors: Array.from(authorCell?.querySelectorAll('a.KnowledgeNetLink') || []).map(a => a.innerText?.trim()),
      journal: sourceCell?.querySelector('a')?.innerText?.trim() || '',
      date: dateCell?.innerText?.trim() || '',
      database: dataCell?.innerText?.trim() || '',
      citations: quoteCell?.innerText?.trim() || '',
      downloads: downloadCell?.innerText?.trim() || '',
      isOnlineFirst: isOnlineFirst
    };
  });

  const totalText = document.querySelector('.pagerTitleCell')?.innerText || '';
  const totalMatch = totalText.match(/([\d,]+)/);
  const pageInfo = document.querySelector('.countPageMark')?.innerText || '';

  return {
    papers: results,
    totalCount: totalMatch ? totalMatch[1] : 'unknown',
    pageInfo: pageInfo
  };
}

3. Present results

Format as a numbered list:

CNKI search results ({totalCount} total, page {pageInfo}):

1. {title} {isOnlineFirst ? "[网络首发]" : ""}
   Authors: {authors joined by "; "}
   Journal: {journal} | Date: {date} | Type: {database}
   Citations: {citations} | Downloads: {downloads}
   URL: {url}

2. ...

4. Fallback: snapshot-based parsing

If JavaScript returns empty (DOM structure changed), use browser action=snapshot mode=efficient and parse the accessibility tree manually:

Look for the repeating pattern:

• checkbox → StaticText (number) → link with URL containing kcms2/article/abstract (title) → links with URL containing kcms2/author/detail (authors) → link with URL containing navi.cnki.net/knavi/detail (journal) → StaticText (date) → StaticText (database type)
