[Corpora-List] XML parsers vs regex

[Mark A. Greenwood]

hmm, not sure that's sensible. In this example you might end up with
extracting a date of "weekafter" if you removed the line breaks.

The moral of the story is ... if you have XML use an XML parser to
extract the data. Yes it might take slightly longer to start with, but
the time spent will be re-paid by not having to worry about weird edge
cases and formatting issues,
