由于这个问题，我一直在拔头发：我正在尝试提取底部代码的Loaction块中包含的文本。我想提取这个：
<h3 class="blue">Location</h3><p class="desc">This elegant luxurious hotel is located in the middle of stunning greenery on a hill, overlooking the sand/ pebble beach of Ixia, which is accessed just over the promenade (around 200 m away). The glamorous building, which is based on architecture from the Middle Ages is stylish and designed in classical, elegant decor. The island's capital of Rhodes Town is located around 4 km from the hotel and Rhodes' airport is roughly 9 km away whilst public transport departs from a stop located just 200 m away.</p>
与
<h3 class="blue">Location<\/h3><p\s(.*)\s.<\/p>
但它不起作用。请有人帮忙。此致

如果您选择的语言有一个解析HTML的库，您应该使用它。正则表达式并不总是最好的工具，但如果您熟悉输入，则可以将它拉下来。
也就是说，你的模式是贪婪的，因此它将超出第一个结束段标记。为了使其不贪婪，您需要使用.*?（注意添加?）。
此外，通常没有必要逃避正斜杠（但我猜您使用的是PHP，基于您的历史记录），使用\s.会导致您的匹配失败，因为文本没有以一个空格后跟一个字符结束。 .是与任何角色匹配的元字符。如果您打算匹配一段时间，则需要将其转义为文字，例如\.。
我更喜欢使用\b来表示字边界，而不是在\s标记之后使用p。最后，除非您想捕获段落文本，否则无需使用捕获组(.*?)。解决所有这些问题让您了解这一点：
<h3 class=\"blue\">Location<\/h3><p\b.*?<\/p>
如果要捕获段落文本，可以采用以下方法：
<h3 class=\"blue\">Location<\/h3><p[^>]*>(.*?)<\/p>
[^>]*匹配任何不大于符号的字符，零次或多次。请注意，这部分模式的好处是它也非贪婪，因为一旦遇到大于符号，匹配就会停止。>匹配大于符号的文字(.*?)捕获内部段落内容的小组答案 1 :(得分：0)
正则表达式的结尾有\s.<\/p>。段落的结尾有ay.</p>。 \s匹配空格字符，但您的输入中有y，匹配失败。

只需删除第一组后的\s即可。在字符串中的任何点之前没有空格。
<h3 class="blue">Location<\/h3><p\s(.*).<\/p>
