使用std::find_if提取序列容器的子串

 1 NodeList OrgTreeParser::findChildsById(const std::string &id)
 2 {
 3     NodeList list;
 4     
 5     auto iter = std::find_if(std::begin(m_list), std::end(m_list),
 6         [&](const OrgTreeNode & item) -> bool {
 7         return item.parent_id.compare(id) == 0;
 8     }
 9     );
10     while (iter != m_list.end())
11     {
12         OrgTreeNode node;
13         node.id = iter->id;
14         node.parent_id = iter->parent_id;
15         node.level_id = iter->level_id;
16         node.name = iter->name;
17         node.addr = iter->addr;
18         node.description = iter->description;
19         list.push_back(node);
20 
21         iter = std::find_if(std::next(iter), std::end(m_list),
22             [&](const OrgTreeNode & item) -> bool {
23             return item.parent_id.compare(id) == 0;
24         }
25         );
26     }
27     
28     return list;
29 }
