python：解析 XML 字段

Question

使用下面的 Python3 脚本，我能够解析 XML 记录并将其转换为列表，（通过从中提取值字段）。

请帮助改进它以使用 XML 记录中的名称“：”值打印。

例如：假设下面一块

<field name="RecordType" value="RESGJG"/>
<field name="RecordTypeHEC" value="PY"/>

得到输出

RESGJG, PY

需要的输出：

RecordType:RESGJG, RecordTypeHEC:PY

我的输入文件：dummy.xml（##请注意它有两条记录##每条记录都以record source="AJS/SHD"开头）

<?xml version="1.0" encoding="UTF-8"?>
<records>
<record source="AJS/SHD" type="call">
<group name="General">
<field name="RecordType" value="RESGJG"/>

我已经尝试过下面的脚本来解析 XML 字段并以列表格式打印。

import sys
import operator
from functools import reduce
from xml.etree.ElementTree import ElementTree

tree = ElementTree()
tree.parse("dummy.xml")
root = tree.getroot()
data = []
groups = root.findall('.//group')
for group in groups:
    data.append([f.attrib['value'] for f in group.findall('./field')])
    q = reduce(operator.concat, data)
    s = ", ".join(q)
print(s)

输出为

RESGJG, PY, rock.dsjjgds.cm, 7937973, 20171049979, 201704059739793, 973979i, normal, dshhkdhs, sdidydakyd2133@10.10.10.1, NotPresent, sip:+47668384, sip:+08779379972, sip:+07073873772@10.0.0.1, sip:+878379739, sip:+937973962, blshahd, ctr, part, 7973, 67367672, 797397, MESGJG, DY, rock.dsjjgds.cm, 7937973, 20171049979, 201704059739793, 973979i, normal, dshhkdhs, sdidydakyd2133@10.10.10.1, NotPresent, sip:+47668384, sip:+08779379972, sip:+07073873772@10.0.0.1, sip:+878379739, sip:+937973962, blshahd, ctr, part, 7973, 67367672, 797397

需要的输出：

RecordType:RESGJG, RecordTypeHEC:PY, NodeID:rock.dsjjgds.cm, SequenceNumber:7937973, StartDate:20171049979, EndDate:201704059739793, CallDuration:973979i, CauseForRecordClosing:normal, ICID:dshhkdhs, CallID:sdidydakyd2133@10.10.10.1, User-Agent:NotPresent, Request-URI:sip:+47668384, CalledPartyNumber:sip:+08779379972, CallingPartyNumber:sip:+07073873772@10.0.0.1, To:sip:+878379739, From:sip:+937973962, VPN_NAME_B:blshahd, VPN_Group_B:ctr, B_ExtType:part, B_ISDN:7973, B_SIP:67367672, B_PABXID:797397,

请帮帮我

Answer 1

您的代码仅获取 value 属性，它完全忽略了 name。

另外，使用reduce 有点矫枉过正。

groups = root.findall('.//group')
for group in groups:
    print(', '.join('{}: {}'.format(field.attrib['name'], field.attrib['value']) for field in group.findall('./field')))
    print()

将输出：

RecordType: RESGJG, RecordTypeHEC: PY, NodeID: rock.dsjjgds.cm, SequenceNumber: 7937973, StartDate: 20171049979, EndDate: 201704059739793, CallDuration: 973979i, CauseForRecordClosing: normal
