使用python 独有etree 方式解析

 1 from xml.etree import ElementTree as et
 2
 3 def parseXml(filename=".\\resource\\test.xml"}):
 4     result_list = []
 5     tree = et.parse(filename)
 6     root = tree.getroot()
 7
 8     elements = root.findall("task")
 9     for el in elements:
10         adict = {}
11         attr = el.attrib # attributes of task node
12         adict.update(attr) # attr is a dict, put the key-values of attr into adict
13         matches = el.findall(‘match‘)
14         for m in matches:
15             key = m.attrib.get(‘property‘)
16             value = m.attrib.get(‘value‘)
17             adict[key] = value
18         props = el.findall(‘property‘)
19         for p in props:
20             key =  p.attrib.get(‘name‘)
21             value = p.attrib.get(‘value‘)
22             adict[key] = value
23         if is_target(adict, filter):
24             result_list.append(adict)
25     return result_list

使用 minidom 解析

 1 from xml.dom.minidom import parse
 2
 3 def load_task_list(filename):
 4     xml_dom = parse(filename)
 5     node_tasklist = xml_dom.documentElement
 6
 7     for node_task in node_tasklist.getElementsByTagName(‘task‘):
 8         for (attr_name, attr_value) in node_task.attributes.items():
 9             print attr_name, attr_value # attributes of task node
10         for node in node_task.childNodes:
11             if node.nodeType == node.ELEMENT_NODE:
12                 if node.nodeName == ‘match‘:
13                     prop_name = node.getAttribute(‘property‘)
14                     prop_value = node.getAttribute(‘value‘)
15                     print ‘match: %s:%s‘%(prop_name, prop_value)
16                 elif node.nodeName == ‘property‘:
17                     prop_name = node.getAttribute(‘name‘)
18                     prop_value = node.getAttribute(‘value‘)
19                     print ‘property: %s:%s‘%(prop_name, prop_value)
20
21 load_task_list(r‘.\resource\test.xml‘)
