#  Get the content of the "species" node for the 1st animal:

result = xml.chilkatPath("animal|species|*")
#  Output should be "pot belly pig"
print result

#  Get the content of the "type" node for the 2nd animal:
#  Indexing begins at 0.  Therefore, the 2nd direct child having
#  the tag "animal" is at index 1
result = xml.chilkatPath("animal[1]|type|*")
#  Output should be "House Pig"
print result

#  Find the pig having the name "Nigel" and display the
#  birth date.  To do this, we'll navigate to the node having
#  tag="name" with the exact content "Nigel", then navigate up,
#  and finally navigate back down to the "birth" node:
result = xml.chilkatPath("/C/name,Nigel|..|birth|*")
#  Output should be "June, 1991"
print result

#  Navigate to the 1st animal's picture and print the filename,
#  description, and caption.
#  The "$" updates the caller's internal pointer to reference
#  the node that is the result of evaluating the path.
#  An empty string is returned for success, and a NULL/nil/0
#  pointer (reference) is returned on failure.

#  Display the contents of the file/description/caption child nodes
print "Picture Info:"
print xml.getChildContent("file")
print xml.getChildContent("description")
print xml.getChildContent("caption")

#  Return back to the root of the XML document:
xml.GetRoot2()

#  Display the value of the "spay-neuter" attribute of the 1st animal:
print "----"
