Using python’s lxml I must read an XML file and print from each “basic” and “expert” tag, the name and email text from it. I’ve done a script that works but I don’t think is the best way of doing this. Is there a better (simpler) way for getting the data of the xml without having to make 2 iterations on it?
Python so far:
from lxml import etree myXML = "data.xml" tree = etree.parse(myXML) root = tree.getroot() for node in root: if node.tag == "basic" or node.tag == "expert": user = [None] * 4 for i, child in enumerate(node): if child.tag == "name": user[0] = i user[1] = child.text if child.tag == "email": user[2] = i user[3] = child.text print user if user[3].startswith('_'): # do some other things with data if email begins with _ ... Will print:
[0, 'f.bar', 1, 'foobar@me.com'] [0, 'm.bob', 3, 'm.bob@email.com'] [0, 'm.bab', 3, 'm.bab@email.com'] XML sample:
<?xml version="1.0"?> <users> <id>11111</id> <checked>True</checked> <version>A12</mode> <basic> <name>f.bar</name> <email>foobar@me.com</email> <forename>Foo</forename> <surname>Bar</surname> </basic> <expert> <name>m.bob</name> <forename>Mak</forename> <surname>Bob</surname> <email>m.bob@email.com</password> </expert> <expert> <name>m.bab</name> <forename>Mak</forename> <surname>Bab</surname> <email>m.bab@email.com</password> </expert> <guru> <name>e.guru</name> <forename>Nick</forename> <email>nick@email.com</password> <surname>Gru</surname> </guru> </users>
