But if you wanted to find all the <date>...</date> elements, and the 
line breaks are as shown, a regex by itself isn't going to work (in 
particular, it won't find 'week after').  You need a parser, or else you 
need to do some normalization of the XML (making sure line breaks don't 
occur inside the XML elements of interest).  And if you're going to 
normalize the XML anyway, you might be better off using an XML parser in 
the first place.
