php regex to remove HTML
提问by Me1000
Before we start, strip_tags() doesn't work.
在我们开始之前，strip_tags() 不起作用。
now,
现在，
I've got some data that needs to be parsed, the problem is, I need to get rid of all the HTML that has been formated very strangely. the tags look like this: (notice the spaces)
我有一些数据需要解析，问题是，我需要摆脱所有格式非常奇怪的 HTML。标签看起来像这样：（注意空格）
< p > blah blah blah < / p > < a href= " link.html " > blah blah blah < /a >
All the regexs I've been trying aren't working, and I don't know enough about regex formating to make them work. I don't care about preserving anything inside of the tags, and would prefer to get rid of the text inside a link if I could.
我一直在尝试的所有正则表达式都不起作用，而且我对正则表达式格式的了解不足以使它们工作。我不在乎保留标签内的任何内容，如果可以的话，我宁愿去掉链接内的文本。
Anyone have any idea?
任何人有任何想法？

strip_tags()will work if you use html_entity_decode()on a variable before strip_tags()
strip_tags()如果您html_entity_decode()之前在变量上使用会起作用strip_tags()
<?php
$text = '< p > blah blah blah < / p > < a href= " link.html " > blah blah blah< /a >';
echo strip_tags(html_entity_decode($text));
?>

Solution which isn't fool-proof, but will work for what you posted:
不是万无一失的解决方案，但适用于您发布的内容：
s/<[^>]*>//g

Formatted strangely? That is valid HTML though right? In that case I wouldn't touch it with regular expressions. Examples of how this can go wrong and why it's a bad idea are legion. Instead I'd use HTML Tidyon it to, for example, clean up unnecessary white-space.
格式奇怪？那是有效的 HTML，对吗？在那种情况下，我不会用正则表达式去碰它。这会如何出错以及为什么这是一个坏主意的例子很多。相反，我会在其上使用HTML Tidy，例如，清理不必要的空白。
