Hello,
I use etree.xmlfile and a coroutine to generate XML into a file-like
object that does post-processing on the XML data. Now, if I use the
send() method to produce invalid XML data, the post-processor throws an
exception.
Here, I see a little problem: No matter what exception is thrown by the
post-processor, the send() method always generates a generic IO
exception. Apparently, lxml catches any exception thrown by the
file-like object and produces a generic IO exception in stead. This
means that there is no way to know what exactly went wrong in the
post-processor. That information is lost.
Inside the coroutine, I *do* get the original exception from the
post-processor, but doing the error handling there is kind of ugly.
Is there a better way to solve this problem?
Thanks a lot!
