我有一个xml文件。 看起来像,
<root>
<Group>
<ChapterNo>1</ChapterNo>
<ChapterName>A</ChapterName>
<Line>1</Line>
<Content>zfsdfsdf</Content>
<Synonyms>fdgd</Synonyms>
<Translation>assdfsdfsdf</Translation>
</Group>
<Group>
<ChapterNo>1</ChapterNo>
<ChapterName>A</ChapterName>
<Line>2</Line>
<Content>ertreter</Content>
<Synonyms>retreter</Synonyms>
<Translation>erterte</Translation>
</Group>
<Group>
<ChapterNo>2</ChapterNo>
<ChapterName>B</ChapterName>
<Line>1</Line>
<Content>sadsafs</Content>
<Synonyms>sdfsdfsd</Synonyms>
<Translation>sdfsdfsd</Translation>
</Group>
<Group>
<ChapterNo>2</ChapterNo>
<ChapterName>B</ChapterName>
<Line>2</Line>
<Content>retete</Content>
<Synonyms>retertret</Synonyms>
<Translation>retertert</Translation>
</Group>
</root>
我试过这种方式.......
root = ElementTree.parse('data.xml').getroot()
ChapterNo = root.find('ChapterNo').text
ChapterName = root.find('ChapterName').text
GitaLine = root.find('Line').text
Content = root.find('Content').text
Synonyms = root.find('Synonyms').text
Translation = root.find('Translation').text
但它显示错误
ChapterNo=root.find('ChapterNo').text
AttributeError: 'NoneType' object has no attribute 'text'`
现在我想让所有ChapterNo,ChapterName等分别使用元素树,我想将这些dats插入数据库....任何人都可以帮助我吗?

要解析简单的两级数据结构并为每个组组装一个dict,您需要做的就是:
>>> # what you did to get `root`
>>> from pprint import pprint as pp
>>> for group in root:
... d = {}
... for elem in group:
... d[elem.tag] = elem.text
... pp(d) # or whack it ito a database
...
{'ChapterName': 'A',
'ChapterNo': '1',
'Content': 'zfsdfsdf',
'Line': '1',
'Synonyms': 'fdgd',
'Translation': 'assdfsdfsdf'}
{'ChapterName': 'A',
'ChapterNo': '1',
'Content': 'ertreter',
'Line': '2',
'Synonyms': 'retreter',
'Translation': 'erterte'}
{'ChapterName': 'B',
'ChapterNo': '2',
'Content': 'sadsafs',
'Line': '1',
'Synonyms': 'sdfsdfsd',
'Translation': 'sdfsdfsd'}
{'ChapterName': 'B',
'ChapterNo': '2',
'Content': 'retete',
'Line': '2',
'Synonyms': 'retertret',
'Translation': 'retertert'}
>>>
看,马,没有x路!

ChapterNo
不是root
的直接孩子,因此root.find('ChapterNo')
无效。您需要使用xpath语法来查找数据。
此外,有多次出现ChapterNo,ChapterName等,因此您应该使用findall
并迭代结果以获取每个文本。
chapter_nos = [e.text for e in root.findall('.//ChapterNo')]
等等。

这是一个使用sqlalchemy
定义一个对象的小例子,该对象将在sqlite数据库中提取和存储数据。
from sqlalchemy import create_engine, Unicode, Integer, Column, UnicodeText
from sqlalchemy.orm import create_session
from sqlalchemy.ext.declarative import declarative_base
engine = create_engine('sqlite:///chapters.sqlite', echo=True)
Base = declarative_base(bind=engine)
class ChapterLine(Base):
__tablename__ = 'chapterlines'
chapter_no = Column(Integer, primary_key=True)
chapter_name = Column(Unicode(200))
line = Column(Integer, primary_key=True)
content = Column(UnicodeText)
synonyms = Column(UnicodeText)
translation = Column(UnicodeText)
@classmethod
def from_xmlgroup(cls, element):
l = cls()
l.chapter_no = int(element.find('ChapterNo').text)
l.chapter_name = element.find('ChapterName').text
l.line = int(element.find('Line').text)
l.content = element.find('Content').text
l.synonyms = element.find('Synonyms').text
l.translation = element.find('Translation').text
return l
Base.metadata.create_all() # creates the table
以下是如何使用它:
from xml.etree import ElementTree as etree
session = create_session(bind=engine, autocommit=False)
doc = etree.parse('myfile.xml').getroot()
for group in doc.findall('Group'):
l = ChapterLine.from_xmlgroup(group)
session.add(l)
session.commit()
我已经在xml数据中测试了这段代码,它可以很好地工作,将所有内容插入到数据库中。
