如何忽略字符串中的http链接并返回其他所有内容？

Question

我正在尝试解析一些HTML内容，这是HTML内容：

<font color="green"> *TITLE* </font> Some Event Name 1:15pm-5:00pm <font color="gold">Stream 5</font><p>
<font color="green"> *TITLE* </font> Some: Event Name 1:30pm-5:00pm <font color="gold">Stream 4</font><p>
<font color="green"> *TITLE* </font> Some, Event Name 1 with num 1:30pm-7:30pm <font color="gold">CHANNEL TWO 2 STREAM http://http://domain.com/path/to/page-2-online.html</font><p>
<font color="green"> *TITLE* </font> Event two 2.45pm-4.45pm <font color="gold">Stream 16</font><p>
<font color="green"> *TITLE* </font> Event THREE summary 2.45pm-4.45pm <font color="gold">Stream 2</font><p>
<font color="green"> *TITLE* </font> Event with a lot of summary 4:00pm-6:00pm <font color="gold">CHANNEL THREE 3 STREAM http://domain.com/path/to/page-3-online.html</font><p>

所以要解析这个并获得“事件名称”，“事件时间”和“流号”，我这样做：

preg_match_all('/<\/font>\s*([^<]+)\s+(\d+.\d+\s*\w{2}\s*-\s*\d+.\d+\s*\w{2}).*?tream\s*(.*?)\s*<\/font><p>/', $data, $matches);

并且它正确地返回所有内容，但是也返回了带有http链接的流号，这是我不想要的。我只想要这个名字（对于某些人而言）＆amp;仅限数字。

需要的数据：

5
4
CHANNEL TWO 2 STREAM
16
2
CHANNEL THREE 3 STREAM

目前它返回：

5
4
-online.html
16
2
-online.html

有人可以帮忙吗？在正则表达式中不是专业人士，过去2天一直在尝试。在此先感谢!!!

Answer 1

但是，如果你想要它在正则表达式，然后根据你的数据，你需要这个

preg_match_all('/(?:<\/font> )((?:[^0-9]+(?:[0-9](?!\.|:|[0-9]))?(?:[0-9]{2}(?!\.|:))?)*)([^<]+) <[^>]+>(?:Stream )?([^h<]+)/', $data, $matches);

这会将名称放在$matches[1]，$matches[2]中的时间和$matches[3]中的频道

---

正则表达式的解释：

1. (?:<\/font> )搜索（并忽略）首先关闭新行上的字体标记，包括空格
2. ((?:[^0-9]+(?:[0-9](?!\.|:|[0-9]))?(?:[0-9]{2}(?!\.|:))?)*)抓住所有不是一两个数字的东西，除非所说的数字后跟一个点或冒号（使用负向前瞻），根据需要重复并分组为一个
3. ([^<]+)抓住所有内容到下一个“＆lt;”，但不是尾随空格
4. <[^>]+>忽略每一个标记，直到下一个“＆gt;”并忽略“＆gt;”以及
5. (?:Stream )?如果第一个字是“流”，则忽略它
6. ([^h<]+)抓住所有内容，直到小写“h”或“＆lt;”

描述

此表达式将：

• 找到所有具有“gold”类
的字体标签
• 如果是第一个单词
，请跳过单词Stream
• 捕捉有趣的文字
• 当它到达http：//链接时停止捕获

<font(?=\s|>)(?=(?:[^>=|&)]*|='[^']*'|="[^"]*"|=[^'"][^\s>]*)*?\scolor=['"]?gold['"]?)(?:[^>=|&)]|='(?:[^']|\\')*'|="(?:[^"]|\\")*"|=[^'"][^\s>]*)*>(?:Stream\s*)?\K(?:(?!\s*https?:|<\/font>).)*

描述

此表达式将：

• 夺取标题
• 捕获活动名称
• 捕获活动时间
• 找到所有有color = gold
的字体标签
• 跳过单词Stream（如果存在）
• 捕捉有趣的文字
• 当它到达http：//链接时停止捕获
• 从比赛周围修剪讨厌的白色空间
• 总体而言，表达式允许字体标记属性出现在字体标记内的任何位置。表达式将避免一些非常困难的边缘情况
