如何获得标题和完整的课程价值？ [英] How do I get the title and complete class value?

问题描述

我有两个查询

1）< div class = ab title =我的标题>
如何获得标题和完整的班级价值？ （ a始终是固定类，而不是 b。第二类可以是任何东西，也可以具有两个以上的类。）

1) <div class="a b" title="my title"> How do I get the title and complete class value ? ('a' always be a fixed class but not 'b'. Second class can be anything and also possiblity to have more than two classes.)

2）< h1><一个link = dynamic_link class = fix-class>我的内容< / a>< / h1>
获取 a href标签的所有属性（链接，类..），它们仅属于 h1标签

2) <h1><a link="dynamic_link" class="fix-class">my content< /a>< /h1> Get all attributes(link,class..) of 'a href' tag which belongs to only 'h1' tag

请帮帮我，因为我从过去两天开始一直坚持这一观点，无法从Google获得任何解决方案。这是我对stackoverflow的第一个问题。希望我能得到很多帮助。

推荐答案

您应该使用XPath查询HTML或XML 。要使用XPath，您必须将HTML加载到DOMDocument对象中。

You should use XPath to query HTML or XML. To use XPath you have to load you HTML into a DOMDocument object.

/* $doc is an instance of DOMDocument */

$xpath = new DOMXPath( $doc );

$myElemnts = $xpath->query( '//li[contains(concat(" ", normalize-space(@class), " "), " classA ")]' );
