正则表达式匹配除< p>之外的所有HTML标记和< / p> [英] Regex to match all HTML tags except <p> and </p>
问题描述
我需要在Perl中使用正则表达式来匹配并删除所有标签。我有以下内容：
I need to match and remove all tags using a regular expression in Perl. I have the following:
<\\??(?!p).+?>
但这仍然与收盘< / p> 标签。任何有关如何与结束标签匹配的提示？
But this still matches with the closing </p> tag. Any hint on how to match with the closing tag as well?
请注意，这是在xhtml上执行的。
Note, this is being performed on xhtml.
I came up with this: △p（= GT; |？\s * GT））\ /?.*?& GT;
x /
< ＃匹配开角尖括号
（？！＃负向前瞻（不匹配并且不消耗）
\ /？＃0或1 /
p＃p
（？=＃Positive lookahead（匹配而不是消费）
>＃> - 无属性
|＃或
\s＃whitespace
。*＃高达
> ;＃关闭尖括号 - 带有属性
）＃关闭正面lookahead
）＃关闭负面lookahead
＃如果我们有这么远，那么我们不匹配
＃ap标签或者关闭p标签
＃带或不带属性
\ /？ ＃可选关闭标记符号（/）
。*？ ＃和任何最多
> ＃第一个结束标记
/
<(?!\/?p(?=>|\s.*>))\/?.*?>
x/
< # Match open angle bracket
(?! # Negative lookahead (Not matching and not consuming)
\/? # 0 or 1 /
p # p
(?= # Positive lookahead (Matching and not consuming)
> # > - No attributes
| # or
\s # whitespace
.* # anything up to
> # close angle brackets - with attributes
) # close positive lookahead
) # close negative lookahead
# if we have got this far then we don't match
# a p tag or closing p tag
# with or without attributes
\/? # optional close tag symbol (/)
.*? # and anything up to
> # first closing tag
/
这将处理带有或不带有属性的p标签，关闭p标签，但会匹配pre和类似标签，有或没有属性。
This will now deal with p tags with or without attributes and the closing p tags, but will match pre and similar tags, with or without attributes.
它不会剥离属性，但我的源数据不会将它们放入。我稍后可能会改变这一点，但现在这已经足够了。
It doesn't strip out attributes, but my source data does not put them in. I may change this later to do this, but this will suffice for now.
