It loops through the child items in entry, looking for one with a
'key' value of 'Track ID'.  If it finds one, it sets found=True and
loops one more time, returning the text of the *next* child element.

It depends on the 'key' element being directly followed by the 'integer'
element within entry.

what the heck this code is doing?

[Basant Dagar]

#See below code:

def lookup(d, keyval):
found = False
for child in d:
if found : return child.text
if child.tag == 'key' and child.text == keyval :
found = True
return None

trackID = lookup(entry, 'Track ID')

 
Below is the main part of input xml file data, it passes to lookup function:

Track ID369

what I don't get is. How in the world it returns value 369 for the variable 
'trackID'??
