DOMDocument 関数を使用して、以下のサンプル HTML コードから 15、Teaching Periods 1 および 2.、Max 150. などのデータを抽出する方法について教えてください。私はそれを回避しようとしましたが、抽出したいテキストの前に複数のタグがあると、抽出したすべてのデータを mysql データベースに保存する必要があるため、すべてのコンテンツを一度に抽出するのが難しくなります。

<B>Module Objective: </B>To introduce students to Internet computer systems, web design, and<BR>client-side programming.<BR><BR>
<B>Module Content: </B>This module provides an introduction to the key concepts of Internet computing. Starting with the fundamentals of computer systems and the Internet, students progress to learn how to design web sites and how to utilize simple client-side programming. Issues related to user interface design and human-computer interfacing (HCI) are covered. Broader issues related to the use of the Internet for Blogging and Social Networks are discussed. The practical element of the module allows students to develop skills necessary for web site design using simple client side programming.<BR><BR>

->nextSibling または xpath を使用してすべての b ノードの後に​​すべてのデータを抽出できると聞きましたが、xpath を使用して必要なすべての関連データを抽出することはできないようです。

あなたはとても親しかった：

$result = array();
foreach($dom->getElementsByTagName('b') as $node){
    $result[preg_replace('/:\s+$/','',$node->textContent)] = trim($node->nextSibling->textContent);
}
var_dump($result);
