I want to use xml.dom.minidom package to parse this file.
self.dom = xml.dom.minidom.parse(self.file)
self.name = self.dom.getElementsByTagName('dict')
print self.name[10].firstChild.data
This code does not seem to work. Basically what I want is to check the 开发者_运维问答value of the second child of dict and then if it is the track I want get the location of the track.
Is there a way to get the dict node which satisfies my conditions?
How about:
import xml.dom.minidom as minidom
dom = minidom.parse('test.xml')
data={}
for dct in dom.getElementsByTagName('dict'):
keys=dct.getElementsByTagName('key')
# key.nextSibling can be an integer or string or date element, or Text node
# key.nextSibling.firstChild is a Text node or None
vals=[key.nextSibling.firstChild for key in keys]
# drill down to the text inside the keys and vals
keys=[key.firstChild.data for key in keys]
vals=[val.data if val else None for val in vals]
data=dict(zip(keys,vals))
if data['Track ID']=='1208':
print(data['Location'])
break
which yields
file://localhost/D:/My%20Music/English%20songs/01-30_seconds_to_mars-kings_and_queens.mp3
