我在Windows和*nix平台上遇到了额外换行的问题。

file = open('UTF16file.xml', 'rb')
html = file.read().decode('utf-16')
file.close()

regexp = re.compile(self.originalurl, re.S)
(html, changes) = regexp.subn(self.newurl, html)

file = open('UTF16file-regexed.xml', 'w+')
file.write(html.encode('utf-16'))
file.close()

在我的Mac上运行这段代码没问题——我得到的文件没有多余的换行。不过到目前为止我尝试过:

  1. 把正则表达式编码成utf-16,而不是解码文件——在Windows和OSX上都出错。

  2. 用'w+'模式写文件,而不是'wb'模式——在Windows上出错。

有什么想法吗?

>>> f.close()
>>> exit()

C:\Documents and Settings\Nick>notepad u16.txt

看起来像这样:

here is allmy text n stuff.

(不过当我从记事本复制粘贴到Firefox时,它实际上加了换行符)……但是这个:

C:\Documents and Settings\Nick>
    "C:\Program Files\Windows NT\Accessories\wordpad.exe" u16.txt

看起来像这样:

here 
is all
my text n stuff.
