问题 I'm attempting to use the lxml module to parse HTML files, but am struggling to get it to work with some UTF-8 encoded data. I'm using Python 2.7 on Windows.

But if I parse the file with lxml,

The problem function is; def collecttemplateurls(templatedir, urlslist): """ Uses BeautifulSoup to

问题 In my program, I need to make use of an ElementTree object in various functions in my program. More specifically, I am doing this: tree = etree.parse('somefile.xml') I am passing this tree around in my program.

Or is my approach ok? 回答1: In Python, (eliding complexities, making an analogy for your C++
