删除标签 - 正则表达式（正则表达式）

I have some HTML and the requirement is to remove only starting <p> tags from the string.

我有一些HTML，并且要求只从字符串中删除起始

标记。

Example:

例：

input: <p style="display:inline; margin: 40pt;"><span style="font:XXXX;"> Text1 Here</span></p><p style="margin: 50pt"><span style="font:XXXX">Text2 Here</span></p> <p style="display:inline; margin: 40pt;"><span style="font:XXXX;"> Text3 Here</span></p>the string goes on like that

desired output: <span style="font:XXXX;"> Text1 Here</span></p><span style="font:XXXX">Text2 Here</span></p><span style="font:XXXX;"> Text3 Here</span></p>

Is it possible using Regex? I have tried some combinations but not working. This is all a single string. Any advice appreciated.

是否可以使用正则表达式？我尝试了一些组合，但没有工作。这只是一个字符串。任何建议表示赞赏

I'm sure you know the warnings about using regex to match html. With these disclaimers, you can do this:

我确定你知道关于使用正则表达式来匹配html的警告。有了这些免责声明，您可以这样做：

Option 1: Leaving the closing </p> tags

选项1：保留结束 标签

This first option leaves the closing </p> tags, but that's what your desired output shows. :) Option 2 will remove them as well.

第一个选项留下结束 标签，但这就是您所需的输出显示的内容。 :)选项2也将删除它们。

PHP

PHP

$replaced = preg_replace('~<p[^>]*>~', '', $yourstring);

JavaScript

JavaScript的

replaced = yourstring.replace(/<p[^>]*>/g, "");

Python

蟒蛇

replaced = re.sub("<p[^>]*>", "", yourstring)

• <p matches the beginning of the tag

• 匹配标记的开头
• The negative character class [^>]* matches any character that is not a closing >
• 否定字符类[^>] *匹配任何不是结束的字符>
• > closes the match
• >结束比赛
• we replace all this with an empty string
• 我们用空字符串替换所有这些

Option 2: Also removing the closing </p> tags

选项2：同时删除结束 标签

PHP

PHP

$replaced = preg_replace('~</?p[^>]*>~', '', $yourstring);

JavaScript

JavaScript的

replaced = yourstring.replace(/<\/?p[^>]*>/g, "");

Python

蟒蛇

replaced = re.sub("</?p[^>]*>", "", yourstring)

This is a PCRE expression:

这是一个PCRE表达式：

/<p( *\w+=("[^"]*"|'[^']'|[^ >]))*>(.*<\/p>)/Ug

Replace each occurrence with $3 or just remove all occurrences of:

用$ 3替换每个匹配项，或者只删除所有出现的：

/<p( *\w+=("[^"]*"|'[^']'|[^ >]))*>/g

If you want to remove the closing tag as well:

如果您还想删除结束标记：

/<p( *\w+=("[^"]*"|'[^']'|[^ >]))*>(.*)<\/p>/Ug
