utf8的问题

X-Bio

我有一个问题:
我有一个文件是UTF8格式的,我想将其中的所有UTF8编码的换行符去掉怎么写正则表达式?
比如:

Integrins play a central role in mediating lymphocyte
adhesion to a number of surfaces. LFA-1 interacts with ICAMs
1-3 that are typically expressed on other immune system cells.
ICAM-4 also interacts with LFA-1, and is known to be
expressed on telencepahlic neurons.<p><p>VCAM-1 regulates
lymphocyte adhesion to activated endothelial cells via Very

他们其实是一行,因为含有UTF8换行符,所以在Excel中换行了.

我使用:
=~ m/\w+/g
可以过滤掉换行符,但是效率太低?

怎么可以通过 ~s///g: 操作去除所有的换行符?


谢谢大家.

先说一下，UTF8的换行符与ASCII的是兼容的

我使用 ~s/\n//g; 处理过,不过不行.

想看看你的那个文件

你是怎样那个文件处理的？
perl -i~ -pe "s/\n//g" 文件名
这样吗？

里面含有 &#xD; 应该是UTF8的换行符吧.

我通过DOM 获取了comment的所有字符换,接下来是想将这种换行符去除.

在控制符可见模式下发现CR,原来不是UTF8的问题,是回车换行惹得祸害;

~s/\r|\n//g;

这样就可以解决我的问题了,我一直以为是UTF8编码的问题.
