这是我的.txt文件,我想把它转换成类似xml的文件

<celldata>
<time> </time>
<latitude> </latitude>
<longitude> </longitude>

</celldata>

我试图列出所有组件,但没有得到 o/p。我想在列表中存储纬度、经度、gsm 单元 ID、时间的所有值,这将在 xml 文件中添加类似的内容。我写下面的代码。

import re

pa = 'Longitude|Latitude|gsm cell id|Neighboring List- Lac : Cid : RSSI'

with open('cell.txt','rw') as file:
for line in file:
line.strip()
if re.search(pa, line):
lineInfo = line.split(':')
title = lineInfo[0]
value = lineInfo[1]

最佳答案

首先尝试使用以下代码:

#!python3

import re
import xml.etree.ElementTree as ET

rex = re.compile(r'''(?P<title>Longitude
|Latitude
|date&time
|gsm\s+cell\s+id
)
\s*:?\s*
(?P<value>.*)
''', re.VERBOSE)

root = ET.Element('root')
root.text = '\n' # newline before the celldata element

with open('cell.txt') as f:
celldata = ET.SubElement(root, 'celldata')
celldata.text = '\n' # newline before the collected element
celldata.tail = '\n\n' # empty line after the celldata element
for line in f:
# Empty line starts new celldata element (hack style, uggly)
if line.isspace():
celldata = ET.SubElement(root, 'celldata')
celldata.text = '\n'
celldata.tail = '\n\n'

# If the line contains the wanted data, process it.
m = rex.search(line)
if m:
# Fix some problems with the title as it will be used
# as the tag name.
title = m.group('title')
title = title.replace('&', '')
title = title.replace(' ', '')

e = ET.SubElement(celldata, title.lower())
e.text = m.group('value')
e.tail = '\n'

# Display for debugging
ET.dump(root)

# Include the root element to the tree and write the tree
# to the file.
tree = ET.ElementTree(root)
tree.write('cell.xml', encoding='utf-8', xml_declaration=True)

它显示您的示例数据:

<root>
<celldata>
<latitude>23.1100348</latitude>
<longitude>72.5364922</longitude>
<datetime>30:August:2014 05:04:31 PM</datetime>
<gsmcellid>4993</gsmcellid>
</celldata>

<celldata>
<latitude>23.1120549</latitude>
<longitude>72.5397988</longitude>
<datetime>30:August:2014 05:04:34 PM</datetime>
<gsmcellid>4993</gsmcellid>
</celldata>

</root>

通缉邻居列表更新:

#!python3

import re
import xml.etree.ElementTree as ET

rex = re.compile(r'''(?P<title>Longitude
|Latitude
|date&time
|gsm\s+cell\s+id
|Neighboring\s+List-\s+Lac\s+:\s+Cid\s+:\s+RSSI
)
\s*:?\s*
(?P<value>.*)
''', re.VERBOSE)

root = ET.Element('root')
root.text = '\n' # newline before the celldata element

with open('cell.txt') as f:
celldata = ET.SubElement(root, 'celldata')
celldata.text = '\n' # newline before the collected element
celldata.tail = '\n\n' # empty line after the celldata element
for line in f:
# Empty line starts new celldata element (hack style, uggly)
if line.isspace():
celldata = ET.SubElement(root, 'celldata')
celldata.text = '\n'
celldata.tail = '\n\n'
else:
# If the line contains the wanted data, process it.
m = rex.search(line)
if m:
# Fix some problems with the title as it will be used
# as the tag name.
title = m.group('title')
title = title.replace('&', '')
title = title.replace(' ', '')

if line.startswith('Neighboring'):
neighbours = ET.SubElement(celldata, 'neighbours')
neighbours.text = '\n'
neighbours.tail = '\n'
else:
e = ET.SubElement(celldata, title.lower())
e.text = m.group('value')
e.tail = '\n'
else:
# This is the neighbour item. Split it by colon,
# and set the attributes of the item element.
item = ET.SubElement(neighbours, 'item')
item.tail = '\n'

lac, cid, rssi = (a.strip() for a in line.split(':'))
item.attrib['lac'] = lac
item.attrib['cid'] = cid
item.attrib['rssi'] = rssi.split()[0] # dBm removed

# Include the root element to the tree and write the tree
# to the file.
tree = ET.ElementTree(root)
tree.write('cell.xml', encoding='utf-8', xml_declaration=True)

接受邻居之前的空行的更新——也为一般目的更好地实现:

#!python3

import re
import xml.etree.ElementTree as ET

rex = re.compile(r'''(?P<title>Longitude
|Latitude
|date&time
|gsm\s+cell\s+id
|Neighboring\s+List-\s+Lac\s+:\s+Cid\s+:\s+RSSI
)
\s*:?\s*
(?P<value>.*)
''', re.VERBOSE)

root = ET.Element('root')
root.text = '\n' # newline before the celldata element

with open('cell.txt') as f:
celldata = ET.SubElement(root, 'celldata')
celldata.text = '\n' # newline before the collected element
celldata.tail = '\n\n' # empty line after the celldata element
status = 0 # init status of the finite automaton
for line in f:
if status == 0: # lines of the heading expected
# If the line contains the wanted data, process it.
m = rex.search(line)
if m:
# Fix some problems with the title as it will be used
# as the tag name.
title = m.group('title')
title = title.replace('&', '')
title = title.replace(' ', '')

if line.startswith('Neighboring'):
neighbours = ET.SubElement(celldata, 'neighbours')
neighbours.text = '\n'
neighbours.tail = '\n'
status = 1 # empty line and then list of neighbours expected
else:
e = ET.SubElement(celldata, title.lower())
e.text = m.group('value')
e.tail = '\n'
# keep the same status

elif status == 1: # empty line expected
if line.isspace():
status = 2 # list of neighbours must follow
else:
raise RuntimeError('Empty line expected. (status == {})'.format(status))
status = 999 # error status

elif status == 2: # neighbour or the empty line as final separator

if line.isspace():
celldata = ET.SubElement(root, 'celldata')
celldata.text = '\n'
celldata.tail = '\n\n'
status = 0 # go to the initial status
else:
# This is the neighbour item. Split it by colon,
# and set the attributes of the item element.
item = ET.SubElement(neighbours, 'item')
item.tail = '\n'

lac, cid, rssi = (a.strip() for a in line.split(':'))
item.attrib['lac'] = lac
item.attrib['cid'] = cid
item.attrib['rssi'] = rssi.split()[0] # dBm removed
# keep the same status

elif status == 999: # error status -- break the loop
break

else:
raise LogicError('Unexpected status {}.'.format(status))
break

# Display for debugging
ET.dump(root)

# Include the root element to the tree and write the tree
# to the file.
tree = ET.ElementTree(root)
tree.write('cell.xml', encoding='utf-8', xml_declaration=True)

代码实现了所谓的有限自动机,其中status 变量表示其当前状态。您可以使用铅笔和纸将其形象化——在内部绘制带有状态编号的小圆圈(在图论中称为节点)。在这种状态下,您只允许某种输入()。当输入被识别时,您将箭头(图论中的定向边)绘制到另一个状态(可能是相同的状态,作为返回同一节点的循环)。箭头注释为`condition |行动”。

结果一开始可能看起来很复杂;但是,从某种意义上说,您始终可以专注于属于特定状态的代码部分,这很容易。而且,代码可以很容易地修改。然而,有限自动机的功率有限。但它们非常适合解决此类问题。
