如何從目錄加載XML文件請

Question

這段代碼我得到了互聯網上的某個地方，我編輯它。

如何從我的目錄加載XML文件？有沒有辦法做到這一點？

from elementtree import ElementTree as et 
# Load the xml content from a string 
content = et.fromstring("C:\DATA\US_Patent_Data\2012\ipgb20120103_wk01\ipgb20120103.xml") 


# Get the person or use the .findall method to get all 
# people if there's more than person 
applicant = content.find("applicant") 
last_name = applicant.find("addressbook/last-name") 
first_name = applicant.find("addressbook/first-name") 

# Get the persons address 
address = addressbook.find("address") 
street = address.find("street") 
city= address.find("city") 
state = address.find("state") 
postcode = address.find("postcode") 
country = address.find("country") 

# Print output 
print "sequence: " + applicant.attrib.get('sequence') 
print "first name: " + first_name.text 
print "last name: " + last_name.text 
print "street: " + street.text 
print "city: " + city.text 
print "state: " + state.text 
print "postcode: " + postcode.text 
print "country: " + country.text 

我跑這個程序，這就是我得到的。 我複製他們的一部分...

File "C:\Python27\lib\site-packages\elementtree\ElementTree.py", line 1292, in feed 
self._parser.Parse(data, 0)

fromstring功能是用於從字符串讀取XML數據。

對於從文件中讀取xml數據，您應該使用parse。有關使用elementtree解析xml的信息，請參閱docs。

import xml.etree.ElementTree as ET 
tree = ET.parse("C:\DATA\US_Patent_Data\2012\ipgb20120103_wk01\ipgb20120103.xml") 
root = tree.getroot() 

UPD： 好像沒有很好地形成你的XML，因爲它有多個根。嘗試添加一個根元素：

with open('ipgb20120103.xml', 'r') as f: 
    xml_string = "<root>%s</root>" % f.read() 

root = ET.fromstring(xml_string)
