修改HTML内容中特定标记中的特定单词

Question

我正在使用PHP进行SEO项目，并希望突出显示HTML内容中的特定单词。修改需要在特定标记上，即<p>标记，而不是其他标记。标题标签（<h1>，<h2>等） 另外，如果任何HTML标记属性包含要替换的特定单词，我希望不会影响它。

<h1>A **SPECIFIC_WORD** information</h1>
<p><img src="some_image.jpg" title="**SPECIFIC_WORD** some other words" />
Lorem Ipsum is simply dummy text of the printing and typesetting industry.
Lorem Ipsum has been the industry's standard dummy text ever since the
1500s, when an unknown printer took a galley of type and scrambled it to make
a type specimen book. It has survived not only five centuries, but also the leap
into electronic typesetting, remaining <a href="#" title="some other words
**SPECIFIC_WORD** other words">essentially unchanged</a>. It was popularised
in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages,
and more recently **SPECIFIC_WORD** with desktop publishing software like Aldus
PageMaker including versions of Lorem Ipsum.</p>

如您所见，SPECIFIC_WORD出现在很多地方，但我想匹配并修改段落文本中的SPECIFIC_WORD，而不是任何标签属性或标题标签。

Answer 1

使用" **SPECIFIC_WORD** "的正则表达式。不是"**SPECIFIC_WORD**"小心保持空间和在**SPECIFIC_WORD**之后
