我正在尝试创建一个脚本,该脚本循环创建xml文件,并为两个元素增加值。 (使用netaddr的IP地址,以及递增的tag / member元素,tag01-tag10)
from netaddr import IPNetwork
import xml.dom.minidom
import lxml.etree as etree
import xml.etree.cElementTree as ET
ip = IPNetwork('10.10.10.0/24')
count = 1
tag = range(1,10)
uid = ET.Element("message")
type = ET.SubElement(uid, "type").text = "update"
payload = ET.SubElement(uid, "payload")
register = ET.SubElement(payload, "register")
entry = ET.SubElement(register, "entry", ip="11.11.11.11")
tag = ET.SubElement(entry, "tag")
ET.SubElement(tag, "member").text = "tag1"
tree = ET.ElementTree(uid)
while count <= 10:
elemtag = tree.findall(".//member")
for elemt in elemtag:
elemt.text = 'tag{}'.format(tag)
elemip = tree.findall(".//entry")
for elemi in elemip:
elemi.text = 'ip="{}"'.format(ip)
count += 1
ET.dump(uid)
print(count)
#tree.write("tmp.xml")
#x = etree.parse("tmp.xml")
#print etree.tostring(x, pretty_print=True)
#etree.parse("tmp.xml").write("pretty.xml", encoding="utf-8", pretty_print=True)
#os.system('tool.py -f pretty.xml')
我弄清楚了如何使用ElementTree创建所需的xml,如果我注释掉了循环并编写了生成的xml,它是正确的,看起来不错,并且可以使用消耗它的工具(是的!)。
<message>
<type>update</type>
<payload>
<register>
<entry ip="11.11.11.11">
<tag>
<member>tag1</member>
</tag>
</entry>
</register>
</payload>
</message>
但是,当我添加循环以替换两个元素的值时,我似乎无法正确理解,并且正在破坏树中的标签/元素。
<message>
<type>update</type>
<payload>
<register>
<entry ip="11.11.11.11">ip="10.10.10.0/24"<tag><member>tag<Element 'tag' at
0x7f7b29d66c90></member></tag></entry>
</register>
</payload>
</message>
我一直在尝试不同的方法来替换元素,但是它们最终都以错误的不同排列而告终,而且我似乎无法正确地做到这一点。希望有人可以帮助我弄清楚我所缺少的。预先感谢!
答案 0 :(得分:0)
我们可以通过以下方式更改元素的属性:
tree.find('.//entry').attrib['ip'] = "22.22.22.22"
“ tag1”是
tag = ET.SubElement(entry, "tag")
根据我们将自己的标签对象分配给标签元素的文本,而不是标签编号。
我更新了您的代码。现在,此解决方案在每次“计数”迭代时生成新的XML
from netaddr import IPNetwork
import xml.etree.cElementTree as ET
ip = IPNetwork('10.10.10.0/24')
tag_lst = list(range(1, 11))
count = 1
uid = ET.Element("message")
type = ET.SubElement(uid, "type").text = "update"
payload = ET.SubElement(uid, "payload")
register = ET.SubElement(payload, "register")
entry = ET.SubElement(register, "entry", ip="11.11.11.11")
tag = ET.SubElement(entry, "tag")
ET.SubElement(tag, "member").text = "tag1"
tree = ET.ElementTree(uid)
while count <= 10:
tree.find('.//member').text = "tag"+str(count)
tree.find('.//entry').attrib['ip'] = format(ip[count])
count += 1
ET.dump(uid)
print(count)
XML输出为:
<message><type>update</type><payload><register><entry ip="10.10.10.1"><tag><member>tag1</member></tag></entry></register></payload></message>
<message><type>update</type><payload><register><entry ip="10.10.10.2"><tag><member>tag2</member></tag></entry></register></payload></message>
<message><type>update</type><payload><register><entry ip="10.10.10.3"><tag><member>tag3</member></tag></entry></register></payload></message>
<message><type>update</type><payload><register><entry ip="10.10.10.4"><tag><member>tag4</member></tag></entry></register></payload></message>
<message><type>update</type><payload><register><entry ip="10.10.10.5"><tag><member>tag5</member></tag></entry></register></payload></message>
<message><type>update</type><payload><register><entry ip="10.10.10.6"><tag><member>tag6</member></tag></entry></register></payload></message>
<message><type>update</type><payload><register><entry ip="10.10.10.7"><tag><member>tag7</member></tag></entry></register></payload></message>
<message><type>update</type><payload><register><entry ip="10.10.10.8"><tag><member>tag8</member></tag></entry></register></payload></message>
<message><type>update</type><payload><register><entry ip="10.10.10.9"><tag><member>tag9</member></tag></entry></register></payload></message>
<message><type>update</type><payload><register><entry ip="10.10.10.10"><tag><member>tag10</member></tag></entry></register></payload></message>
