python 解析xml檔案

et.parser 用法

python3 xml解析模組xml.etree.elementtree簡介

刪除重複xml節點

import xml.etree.elementtree as et----------匯入xml模組

root = et.parse('gho.xml')------------------分析指定xml檔案

tree = root.getroot()-----------------------獲取第一標籤

data = tree.find('data')--------------------查詢第一標籤中'data'標籤

for obs in data:----------------------------歷遍'data'中的所有標籤

for item in obs:------------------------歷遍'data'中的'obs'標籤下的所有標籤

key = item.attrib()-----------------提取key值引數

print(list(key))--------------------輸出key值 

如何讀取屬性及節點內容。

怎樣將data中的 id,name及其值取出來？

問題解釋

兩種方式：

1.先取得node

string strid = node.getattributes().getnameditem("id").getnodevalue();

string strname = node.getattributes().getnameditem("name").getnodevalue();

2.先取得element

string strid = element.getattribute("id");

string strname = element.getattribute("name");

小練習

#!/usr/bin/env python

import sys
import xml.etree.elementtree as et
tree = et.parse('abcdefg.xml')
root = tree.getroot()
iter_elem = root.findall('.//*')
print(len(iter_elem))
#elem = root.find('')
#print iter_elem
for element in iter_elem:
if element is none:
continue
if element.text is none:
continue
print("hello")
context=	
src_elem = element.find("source")
if src_elem is none:
continue
print( "attri :%s"%src_elem.attrib)
print("tag :%s"%src_elem.tag)		
#for item in src_elem:
#    key = item.text()
#    print list(key)
del duplicatd node:

import xml.etree.elementtree as et

path = 'in.xml'
tree = et.parse(path)
root = tree.getroot()
prev = none
def elements_equal(e1, e2):
if type(e1) != type(e2):
return false
if e1.tag != e1.tag: return false
if e1.text != e2.text: return false
if e1.tail != e2.tail: return false
if e1.attrib != e2.attrib: return false
if len(e1) != len(e2): return false
return all([elements_equal(c1, c2) for c1, c2 in zip(e1, e2)])
for page in root:                     # iterate over pages
elems_to_remove = 
for elem in page:
if elements_equal(elem, prev):
print("found duplicate: %s" % elem.text)   # equal function works well
continue
prev = elem
for elem_to_remove in elems_to_remove:
page.remove(elem_to_remove)
tree.write("out.xml")
