XML 正在解析为 .txt 文件 Python
XML Parsing to .txt file Python
我需要解析此 XML Document 并将日期和时间移动到 %Y-%m-%d %H:%M:%S 格式以及变量 hourly-qpf 和 probability-of-precipitation 到选项卡中的列-分隔的 .txt 文件。
我所做的就是使用以下代码在 XML 文件中读取：
page = urllib2.urlopen('http://forecast.weather.gov/MapClick.php?lat=47.6062&lon=-122.3321&FcstType=digitalDWML')
page_content = page.read()
with open('KBFI.xml', 'w') as fid:
fid.write(page_content)
这之后我就不知所措了。我之前只解析过一个XML文档，和这个看起来完全不一样。

很抱歉之前没有任何东西可以给你们，但我不确定该使用什么模块，因为我只有 minidom 的经验，它似乎不是正确的选择。我一直在摆弄 Element Tree，我想出了这个：
data = []
import xml.etree.ElementTree as ET
tree = ET.parse('KBFI.xml')
root = tree.getroot()
for data in root.findall('data'):
for time-layout in root.findall('time-layout'):
start-valid-time = time-layout.find('start-valid-time')
time = datetime.datetime.strptime(start-valid-time, '%Y-%m-%dT%H:%M:%S')
for parameters in root.findall('parameters'):
for probability-of-precipitation in root.findall('probability-of-precipitation'):
value = probability-of-precipitation.find('value')
for hourly-qpf in root.findall('hourly-qpf'):
value2 = hourly-qpf.find('value')
data = data.append([time,
value,
value2])
with open('KBFI.txt','w') as file:
file.writelines('\t'.join(map(str,i)) + '\n' for i in data)
但是，有一个问题，因为变量是带连字符的，我不知道如何将它们更改为下划线或删除它们。另外，正因为如此，我不知道我的代码是否好用！
您可以使用 python xml 库:
https://docs.python.org/2/library/xml.etree.elementtree.html
import urllib2
import xml.etree.ElementTree as ET
page = urllib2.urlopen('http://forecast.weather.gov/MapClick.php?lat=47.6062&lon=-122.3321&FcstType=digitalDWML')
page_content = page.read()
root = ET.fromstring(page_content)
for _f in root.itertext():
***Do your formatting here***
我建议使用 xmltodict 从 XML 中解析和提取数据，因为它直接且易于使用，因为它将 XML 转换为 Python 与 XML来源。对于那些熟悉 Python 语法的人来说，使用它是很自然的，而且 Python 字典是完全通用的，这意味着它们能够表达异构和嵌套的数据结构。例如，Pickling Tools Library 依赖于 Python 字典实现 Python、C++ 和 Java 数据互操作性，并提供将 XML 转换为字典的工具。 xmltodict 的优点是它的小，快，和一个独立的模块只是为了将 XML 转换为 dict.
作为 xmltodict 用法的示例，以下脚本下载 this XML document 并提取其创建日期以及降水概率和每小时 qpf 值的列表：
import requests
url='http://forecast.weather.gov/MapClick.php?lat=47.6062&lon=-122.3321&FcstType=digitalDWML'
r = requests.get(url)
import xmltodict
result = xmltodict.parse(r.text)
cd = result['dwml']['head']['product']['creation-date']['#text']
print("creation-date =",cd)
pop = result['dwml']['data']['parameters']['probability-of-precipitation']['value']
print("\nprobability-of-precipitation =", pop)
hqpf = result['dwml']['data']['parameters']['hourly-qpf']['value']
print("\nhourly-qpf =", hqpf)
这是 运行 此脚本（20150730 上）的输出：
creation-date = 2015-07-30T08:53:12-07:00
probability-of-precipitation = ['0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '7', '7', '7', '7', '7', '7', '7', '7', '7', '7', '7', '7', '5', '5', '5', '5', '5', '5', '5', '5', '5', '5', '5', '5', '8', '8', '8', '8', '8', '8', '8', '8', '8', '8', '8', '8', '6', '6', '6', '6', '6', '6', '6', '6', '6', '6', '6', '6', '13', '13', '13', '13', '13', '13', '13', '13', '13', '13', '13', '13', '19', '19', '19', '19', '19', '19', '19', '19', '19', '19', '19', '19', '28', '28', '28', '28', '28', '28']
hourly-qpf = ['0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0.0067', '0.0067', '0.0067', '0.0067', '0.0067', '0.0067', '0.0033', '0.0033', '0.0033', '0.0033', '0.0033', '0.0033', '0.0067', '0.0067', '0.0067', '0.0067', '0.0067', '0.0067']
xmltodict 可以与 'pip install xmltodict' 一起安装。它由 Martin Blech 开发，其 GitHub 项目位于 https://github.com/martinblech/xmltodict。
为了访问开始有效时间和结束有效时间，有助于了解它们的数据结构及其位置。由于两者都是包含在相同标签中的一系列值，因此直观上每个系列应该形成一个单独的列表作为键的值，其名称类似于 probability-of-precipitation 和 hourly-qpf。这可以通过打印整个结果字典并检查其中的开始有效时间和结束有效时间的格式来确认，并且可以通过漂亮地打印结果字典（使用 import pprint 然后 运行 pprint.pprint（结果））。对于 this XML document，漂亮的打印其等效字典生成了 2000 多行，但是 start-valid-time 从第 26 行开始并且它的值显然是一个列表：

这是一个脚本，它提取并打印创建日期作为标量值、列表中的所有开始有效时间值、列表中的所有结束有效时间值、所有降水概率值在列表中和列表中的所有 hourly-qpf 值并打印每个提取列表的长度：
import xmltodict
result = xmltodict.parse(r.text)
cd = result['dwml']['head']['product']['creation-date']['#text']
print("creation-date =",cd)
svt = result['dwml']['data']['time-layout']['start-valid-time']

print("number of start-valid-time entries =", len(svt))

hqpf = result['dwml']['data']['parameters']['hourly-qpf']['value']

我需要解析此 XML Document 并将日期和时间移动到 %Y-%m-%d %H:%M:%S 格式以及变量 hourly-qpf 和 probability-of-precipitation 到选项卡中的列-分隔的 .txt 文件。
我所做的就是使用以下代码在 XML 文件中读取：
page = urllib2.urlopen('http://forecast.weather.gov/MapClick.php?lat=47.6062&lon=-122.3321&FcstType=digitalDWML')
page_content = page.read()
with open('KBFI.xml', 'w') as fid:
fid.write(page_content)
这之后我就不知所措了。我之前只解析过一个XML文档，和这个看起来完全不一样。

很抱歉之前没有任何东西可以给你们，但我不确定该使用什么模块，因为我只有 minidom 的经验，它似乎不是正确的选择。我一直在摆弄 Element Tree，我想出了这个：
data = []
import xml.etree.ElementTree as ET
tree = ET.parse('KBFI.xml')
root = tree.getroot()
for data in root.findall('data'):
for time-layout in root.findall('time-layout'):
start-valid-time = time-layout.find('start-valid-time')
time = datetime.datetime.strptime(start-valid-time, '%Y-%m-%dT%H:%M:%S')
for parameters in root.findall('parameters'):
for probability-of-precipitation in root.findall('probability-of-precipitation'):
value = probability-of-precipitation.find('value')
for hourly-qpf in root.findall('hourly-qpf'):
value2 = hourly-qpf.find('value')
data = data.append([time,
value,
value2])
with open('KBFI.txt','w') as file:
file.writelines('\t'.join(map(str,i)) + '\n' for i in data)
但是，有一个问题，因为变量是带连字符的，我不知道如何将它们更改为下划线或删除它们。另外，正因为如此，我不知道我的代码是否好用！
您可以使用 python xml 库:
https://docs.python.org/2/library/xml.etree.elementtree.html
import urllib2
import xml.etree.ElementTree as ET
page = urllib2.urlopen('http://forecast.weather.gov/MapClick.php?lat=47.6062&lon=-122.3321&FcstType=digitalDWML')
page_content = page.read()
root = ET.fromstring(page_content)
for _f in root.itertext():
***Do your formatting here***
我建议使用 xmltodict 从 XML 中解析和提取数据，因为它直接且易于使用，因为它将 XML 转换为 Python 与 XML来源。对于那些熟悉 Python 语法的人来说，使用它是很自然的，而且 Python 字典是完全通用的，这意味着它们能够表达异构和嵌套的数据结构。例如，Pickling Tools Library 依赖于 Python 字典实现 Python、C++ 和 Java 数据互操作性，并提供将 XML 转换为字典的工具。 xmltodict 的优点是它的小，快，和一个独立的模块只是为了将 XML 转换为 dict.
作为 xmltodict 用法的示例，以下脚本下载 this XML document 并提取其创建日期以及降水概率和每小时 qpf 值的列表：
import requests
url='http://forecast.weather.gov/MapClick.php?lat=47.6062&lon=-122.3321&FcstType=digitalDWML'
r = requests.get(url)
import xmltodict
result = xmltodict.parse(r.text)
cd = result['dwml']['head']['product']['creation-date']['#text']
print("creation-date =",cd)
pop = result['dwml']['data']['parameters']['probability-of-precipitation']['value']
print("\nprobability-of-precipitation =", pop)
hqpf = result['dwml']['data']['parameters']['hourly-qpf']['value']
print("\nhourly-qpf =", hqpf)
这是 运行 此脚本（20150730 上）的输出：
creation-date = 2015-07-30T08:53:12-07:00
probability-of-precipitation = ['0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '1', '7', '7', '7', '7', '7', '7', '7', '7', '7', '7', '7', '7', '5', '5', '5', '5', '5', '5', '5', '5', '5', '5', '5', '5', '8', '8', '8', '8', '8', '8', '8', '8', '8', '8', '8', '8', '6', '6', '6', '6', '6', '6', '6', '6', '6', '6', '6', '6', '13', '13', '13', '13', '13', '13', '13', '13', '13', '13', '13', '13', '19', '19', '19', '19', '19', '19', '19', '19', '19', '19', '19', '19', '28', '28', '28', '28', '28', '28']

xmltodict 可以与 'pip install xmltodict' 一起安装。它由 Martin Blech 开发，其 GitHub 项目位于 https://github.com/martinblech/xmltodict。
为了访问开始有效时间和结束有效时间，有助于了解它们的数据结构及其位置。由于两者都是包含在相同标签中的一系列值，因此直观上每个系列应该形成一个单独的列表作为键的值，其名称类似于 probability-of-precipitation 和 hourly-qpf。这可以通过打印整个结果字典并检查其中的开始有效时间和结束有效时间的格式来确认，并且可以通过漂亮地打印结果字典（使用 import pprint 然后 运行 pprint.pprint（结果））。对于 this XML document，漂亮的打印其等效字典生成了 2000 多行，但是 start-valid-time 从第 26 行开始并且它的值显然是一个列表：

这是一个脚本，它提取并打印创建日期作为标量值、列表中的所有开始有效时间值、列表中的所有结束有效时间值、所有降水概率值在列表中和列表中的所有 hourly-qpf 值并打印每个提取列表的长度：
import xmltodict
result = xmltodict.parse(r.text)
cd = result['dwml']['head']['product']['creation-date']['#text']
print("creation-date =",cd)
svt = result['dwml']['data']['time-layout']['start-valid-time']
print("\nstart-valid-time =", svt)
print("number of start-valid-time entries =", len(svt))
evt = result['dwml']['data']['time-layout']['end-valid-time']
print("\nend-valid-time =", evt)
print("number of end-valid-time entries =", len(evt))
pop = result['dwml']['data']['parameters']['probability-of-precipitation']['value']
print("\nprobability-of-precipitation =", pop)
print("number of probability-of-precipitation entries =", len(pop))
hqpf = result['dwml']['data']['parameters']['hourly-qpf']['value']
print("\nhourly-qpf =", hqpf)
print("number of hourly-qpf entries =", len(hqpf))
这是 运行 此脚本（20150731 上）的输出：
