can we use xpath with BeautifulSoup?
... Martijn's code no longer works properly (it is 4+ years old by now...), the etree.parse() line prints to the console and doesn't assign the value to the tree variable. That's quite a claim. I certainly can't reproduce that, and it would not make any sense. Are you sure you are using Pyth...

Now, 2017, you can do it easier with the new MSTest V2 Framework:

What are best practices for using SmtpClient, SendAsync and Dispose under .NET 4.0
I'm a bit perplexed on how to manage SmtpClient now that it is disposable, especially if I make calls using SendAsync. Presumably I should not call Dispose until SendAsync completes. But should I ever call it (e.g., using "using"). The scenario is a WCF service which mails out email periodically ...

Static methods in Python?
...umber of arguments, but would also cause an exception to be raised because now n would be representing a Dog instance (i.e., rex) when the function expects n to be numerical.
This is where the decoration comes in:

Apache Spark: The number of cores vs. the number of executors
...son, but we still see a similar drop in performance when we lose threads.
Now for the last bit: why is it the case that we get better performance with more threads, esp. more threads than the number of CPUs?
A good explanation of the difference between parallelism (what we get by dividing up data ...
Windows batch files: .bat vs .cmd?

I understand now. I updated my gist. Apparently, it doesn't (re)set the errorlevel when calling a set var=.. statement. Which is odd, because I assumed that was expected behavior. Arguments could be made for both. I'll stick with .bat fil...
