嘿朋友我正在使用Python库生成XML数据,如下所示
def multiwan_info_save(request):
data = {}
init = "init"
try:
form = Addmultiwanform(request.POST)
except:
pass
if form.is_valid():
from_sv = form.save(commit=False)
obj_get = False
try:
obj_get = MultiWAN.objects.get(isp_name=from_sv.isp_name)
except:
obj_get = False
nameservr = request.POST.getlist('nameserver_mw')
for nm in nameservr:
nameserver1, is_new = NameServer.objects.get_or_create(name=nm)
from_sv.nameserver = nameserver1
from_sv.save()
# main(init)
top = Element('ispinfo')
# comment = Comment('Generated for PyMOTW')
#top.append(comment)
all_connection = MultiWAN.objects.all()
for conn in all_connection:
child = SubElement(top, 'connection number ='+str(conn.id)+'name='+conn.isp_name+'desc='+conn.description )
subchild_ip = SubElement(child,'ip_address')
subchild_subnt = SubElement(child,'subnet')
subchild_gtwy = SubElement(child,'gateway')
subchild_nm1 = SubElement(child,'probe_server1')
subchild_nm2 = SubElement(child,'probe_server2')
subchild_interface = SubElement(child,'interface')
subchild_weight = SubElement(child,'weight')
subchild_ip.text = str(conn.ip_address)
subchild_subnt.text = str(conn.subnet)
subchild_gtwy.text = str(conn.gateway)
subchild_nm1.text = str(conn.nameserver.name)
# subchild_nm2.text = conn.
subchild_weight.text = str(conn.weight)
subchild_interface.text = str(conn.interface)
print "trying to print _____________________________"
print tostring(top)
print "let seeeeeeeeeeeeeeeeee +++++++++++++++++++++++++"
但我得到的输出如下
<ispinfo><connection number =5name=Airtelllldesc=Largets TRelecome ><ip_address>192.168.1.23</ip_address><subnet>192.168.1.23</subnet><gateway>192.168.1.23</gateway><probe_server1>192.168.99.1</probe_server1><probe_server2 /><interface>eth0</interface><weight>160</weight></connection number =5name=Airtelllldesc=Largets TRelecome ><connection number =6name=Uninordesc=Uninor><ip_address>192.166.55.23</ip_address><subnet>192.166.55.23</subnet><gateway>192.168.1.23</gateway><probe_server1>192.168.99.1</probe_server1><probe_server2 /><interface>eth0</interface><weight>160</weight></connection number =6name=Uninordesc=Uninor><connection number =7name=Airteldesc=Largets TRelecome ><ip_address>192.168.1.23</ip_address><subnet>192.168.1.23</subnet><gateway>192.168.1.23</gateway><probe_server1>192.168.99.1</probe_server1><probe_server2 /><interface>eth0</interface><weight>160</weight></connection number =7name=Airteldesc=Largets TRelecome ></ispinfo>
我只想知道如何以适当的XML格式编写此XML?

更新以包括创建和打印XML树的模拟
您的代码生成了无效的连接标记,如下所示:
<connection number =5name=Airtelllldesc=Largets TRelecome ></connection number =5name=Airteldesc=Largets TRelecome >
当它们看起来像这样时(我省略了它们之间的子元素。你的代码正确地生成了这些元素):
<connection number="5" name="Airtellll" desc="Largets TRelecome" ></connection>
如果你有有效的XML,这段代码会整齐地打印出来:
from lxml import etree
xml = '''<ispinfo><connection number="5" name="Airtellll" desc="Largets TRelecome" ><ip_address>192.168.1.23</ip_address><subnet>192.168.1.23</subnet><gateway>192.168.1.23</gateway><probe_server1>192.168.99.1</probe_server1><probe_server2 /><interface>eth0</interface><weight>160</weight></connection></ispinfo>'''
xml = etree.XML(xml)
print etree.tostring(xml, pretty_print = True)
小模拟如下:
from lxml import etree
# Some dummy text
conn_id = 5
conn_name = "Airtelll"
conn_desc = "Largets TRelecome"
ip = "192.168.1.23"
# Building the XML tree
# Note how attributes and text are added, using the Element methods
# and not by concatenating strings as in your question
root = etree.Element("ispinfo")
child = etree.SubElement(root, 'connection',
number = str(conn_id),
name = conn_name,
desc = conn_desc)
subchild_ip = etree.SubElement(child, 'ip_address')
subchild_ip.text = ip
# and pretty-printing it
print etree.tostring(root, pretty_print=True)
这将产生:
<ispinfo>
<connection desc="Largets TRelecome" number="5" name="Airtelll">
<ip_address>192.168.1.23</ip_address>
</connection>
</ispinfo>

单行正确,从某种意义上说,XML解析器会理解它。
要对sys.stdout
进行漂亮打印,请使用dump
的{{1}}方法。
要对流进行漂亮打印,请使用Element
的{{1}}方法。
