DOM is not very good for this sort of thing. You could do:
print xml.getElementsByTagName("content")[0].firstChild.data
print xml.getElementsByTagName("content")[1].getElementsByTagName
("b").firstChild.data
But that's silly :-)

Your b element happens to have the same name as one used in HTML, but
that doesn't really make it an HTML tag. In this case, it's clearly an
XML tag.

Use something like the string_value function, listing 5 of the following
article:
http://www.xml.com/pub/a/2003/01/08/py-xml.html
Or use something with XPath support, which makes this easy. Using Amara
( http://www.xml.com/pub/a/2005/01/19/amara.html ), your code would be
from amara import binderytools
doc = binderytools.bind_file("test.xml")
print doc.xml_xpath(u'string(//content[1])')
print doc.xml_xpath(u'string(//content[2])')
Which prints
Hello
Hello
The string XPath function gets all text nodes, even within contained
elements. Notice that XPath uses 1 as the first index, while Python
uses 0.
