如何用BeautifulSoup获取指定节点后的div/p节点并遇h1/2/3停止

Got it, let's tackle this problem step by step. You've already nailed getting that target red-highlighted node with your find call, so now we just need to gather all the following <div> and <p> nodes until we hit an <h1>, <h2>, or <h3>.

Approach for Sibling Nodes (Most Likely Scenario) #

If the blue-marked nodes are siblings that come right after your target node, use this sibling traversal method:

# Your existing target node is stored in the `title` variable
result_nodes = []
current_node = title.next_sibling

while current_node is not None:
    # Skip empty text nodes (like newlines/spaces in raw HTML)
    if current_node.name is None:
        current_node = current_node.next_sibling
        continue
    
    # Stop immediately when we hit any heading tag
    if current_node.name in ['h1', 'h2', 'h3']:
        break
    
    # Add valid div/p nodes to our result list
    if current_node.name in ['div', 'p']:
        result_nodes.append(current_node)
    
    # Move to the next sibling node
    current_node = current_node.next_sibling

How This Works: #

• We start traversing right after your target node using next_sibling
• We filter out blank text nodes (BeautifulSoup treats whitespace/newlines as separate nodes, so we need to skip those to avoid clutter)
• As soon as we encounter an h1/h2/h3, we break the loop to stop collecting further nodes
• Any div or p nodes found before hitting those headings get added to our result list

If Target Nodes Are Direct Children #

If the blue-marked nodes are direct children of your red-highlighted target node instead of siblings, adjust the code to iterate over the target's children:

result_nodes = []
for child in title.children:
    if child.name is None:
        continue
    if child.name in ['h1', 'h2', 'h3']:
        break
    if child.name in ['div', 'p']:
        result_nodes.append(child)

Either implementation will give you exactly the list of nodes you need, stopping as soon as those heading tags are encountered.
