查找所有 PHP 短标签
我需要找到所有短 PHP 标签。
它的正则表达式 <\?(?!php) 但我不能在 vim 中使用它。
如何将其“转换”为vim？
I need to find all short PHP tags.
The regex for it <\?(?!php) but I can not use it in vim.
How to "convert" it to vim?

对我来说这个效果很好：
For me this one worked fine:
在 vim 中查找短标签的最佳方法是查找所有出现
且后面没有p的情况：您的正则表达式在 vim 中失败的原因是 < code>/? 查找文字问号，而
\?是量词； vim 中的/<\?将尝试查找 0 或 1 个小于号。这与您在大多数正则表达式引擎中所期望的相反。如果您想匹配紧随其后的换行符的短标记，则不能使用
[^p]，这需要有 something 来匹配不存在的内容t ap。在这种情况下，您可以将“not p or end-of-line”与The best way to find short-tags in vim is to find all occurrences of
<?not followed by ap:The reason your regex is failing in vim is because
/?finds literal question marks, while\?is a quantifier;/<\?in vim will attempt to find 0 or 1 less-than signs. This is backwards from what you might expect in most regular expression engines.If you want to match short tags that are immediately followed by a new line, you cannot use
[^p], which requires there to be something there to match which isn't ap. In this case, you can match "not p or end-of-line" with查找

解释
仅匹配短标签
<\?，后跟空格、制表符或换行符(\t|\n|\s) 并将其存储在$1中。此处提供的所有解决方案都与该行不包含的内容相匹配，而不是我们知道它将保证包含的内容。这允许您的代码格式保持相同，仅在需要时添加文本
php。我们只想匹配短标签，而不应该关心后面的内容（php/xml/= 等）。此查找/替换将匹配内联短标签和单独行上的短标签。
注意：如果您使用 Windows 换行符，
<\?(\t|\r\n|\s)将匹配相同的换行符。Find
Replace
Explanation
Match only short tags
<\?, followed by white-space, tab or newline(\t|\n|\s)and store it in$1All of the solutions provided here match what the line doesn't contain, instead of what we know it will be guaranteed to contain. This allows your code formatting to remain identical, only adding the text
phpwhere needed.We only ever want to match the short tag, and shouldn't care what comes after (php/xml/= etc). This find/replace will match both inline short tags and short tags on a separate line.
Note: If you're using Windows line-breaks,
<\?(\t|\r\n|\s)will match the same.使用（最新版本的）

要匹配
