需要一个正则表达式来解析HTML标签 [英] Need a regular expression to parse HTML tags

问题描述

正则表达式不是我的专长，可以在匹配和替换下列方面真正做到：

在HTML文件中，我有很多HTML实例，如下所示：

 < font class = font8>文字文字文字< / font> 
  

字体标签在单个单词或多个单词中可以有不同的内容，可以是空格，也可以是数字。 / p>

我需要找到所有这个实例并替换为：

  < span class =bold>（在那里的文字）< / span> 
  

感谢

PS：HTML是从word生成的，这就是为什么它很糟糕：o）使用解决方案使用 getElementsByTagName（'font'）和 DOMDocument :: loadHTML 方法并遍历基于 - >对于类名称值为，然后 createElement（'span'）和 setAttribute 粗体，做一个 replaceChild 来替换它。

DOM的参考： http://php.net/manual/en/book.dom.php

Regular expressions are not my forte and could really do with assistance on matching and replacing the following:

In a HTML file I have many instances of HTML like this:

<font class=font8>text text text</font>

The font tag can have different content in either single word or multiple word with spaces and maybe numbers.

I need to find all instances of this and replace with:

<span class="bold">(text that was there)</span>

Thanks James

PS: the HTML was generated from word that is why it is so bad :o)

解决方案

Use getElementsByTagName('font') and the DOMDocument::loadHTML method and iterate through the nodelist based in the ->length, then createElement('span') and setAttribute for the class name value of bold, do a replaceChild to replace it.
