Question

我希望匹配一个HTML代码，直到下一次出现......或结束。

目前我有以下正则表达式：

(<font color=\"#777777\">\.\.\. .+?<\/font>)

只会与之匹配：

1. <font color="#777777">... </font><font color="#000000">lives up to the customer's expectations. The subscriber is </font>
2. <font color="#777777">... You may not want them to be </font>
3. <font color="#777777">... </font><font color="#000000">the web link, and </font>

但我想要：

1. <font color="#777777">... </font><font color="#000000">lives up to the customer's expectations. The subscriber is </font><font color="#777777">obviously thinking about your merchandise </font><font color="#000000">in case they have clicked about the link in your email.</font>
2. <font color="#777777">... You may not want them to be </font><font color="#000000">disappointed by simply clicking </font>
3. <font color="#777777">... </font><font color="#000000">the web link, and </font><font color="#777777">finding </font><font color="#000000">the page to </font><font color="#777777">get other than </font><font color="#000000">what they thought it </font><font color="#777777">will be.. If America makes</font>

这是我要解析的html：

<font color="#777777">... </font><font color="#000000">lives up to the customer's expectations. The subscriber is </font><font color="#777777">obviously thinking about your merchandise  </font><font color="#000000">in case they have clicked about the link in your email.</font><font color="#777777">... You may not want them to be </font><font color="#000000">disappointed by simply clicking </font><font color="#777777">... </font><font color="#000000">the web link, and </font><font color="#777777">finding  </font><font color="#000000">the page to </font><font color="#777777">get other than  </font><font color="#000000">what they thought it </font><font color="#777777">will be.. If America makes</font>

如何匹配所有以...开头的文字以获得上述所需的匹配？

感谢您的帮助！

Answer 1

即使你的问题似乎不一致（我不明白为什么你会得到最后的期望匹配），我认为这就是你所追求的：

((<font color=\"#777777\">\.{3}) .+?(<\/font>(?=\s*\2)|$))

它使用预测来使匹配结束只是之前下一个“...”序列（或输入结束。

Answer 2

问题是关于regexp，但你也可以通过以下方式完成它（Perl语法，但我相信这种函数也存在于其他语言中）：

split(/(?=<font color=\"#777777\">\.\.\.)/, $your_text)

匹配所有内容直到下一场比赛
