我试图读取的数据是 xml 格式。xml 声明前有一个空格。我无法编辑这部分，因为它被硬编码到数据源中。我只能从中读取。当在 IE 中输入 url 时，数据就会出现。在 Chrome/Firefox 中输入时，会显示错误，但可以从查看源查看数据。

python有没有办法像IE一样去掉这个空间或者忽略它？

（尝试strip()在很多地方添加）

或者有没有办法默认页面源（我认为 urlopen 已经这样做了）？

这是给出错误的行：

html = urlopen(address).read()

这是错误：

Traceback (most recent call last):

  html = urlopen(address).read()
