我有一个每天需要修改的xml文件。为bash或xmlstarlet写的非常简单的东西.....或任何简单的东西。下面的字符串只是需要更改的千个通道之一。因此，它必须解析每一行并将site_id复制到xmltv_id。谢谢您的帮助。
它创建了这个。.
1 import numpy as np
2
3 class State:
4 state = np.zeros(8)
5 fitness=0
6 normalizedFitness=0
7
8 def __init__(self, state):
9 self.state = state
10 self.fitness = hash(self)
11
12 #the hash is used to find the fitness
13 #the fitness is defined by the number of non attacking queens
14 def __hash__(self):
15 count = 0
16 attackingQueens = [False,False,False,False,False,False,False,False]
17 for i in range(0,7):
18 x1 = i+1
19 y1 = self.state[i]
20 for j in range(i+1,8):
21 x2 = j+1
22 y2 = self.state[j]
23 if y1==y2 or abs((x1-x2))==abs((y1-y2)):
24 attackingQueens[i]=True
25 attackingQueens[j]=True
26 for attacking in attackingQueens:
27 if not attacking:
28 count+=1
29 self.fitness=count
30 return count
我需要将site_id值复制到xmltv_id值。
channel update="i" site="merge-xmltv" site_id="citytoronto.ca" xmltv_id="CITY TV (Toronto ON) (CAN)">CITY TV (Toronto ON) (CAN)
答案 0 :(得分：0)
这有效
sed -i 's/site_id="([^"])" xmltv_id="[^"]"/site_id="\1" xmltv_id="\1"/g' WebGrab++.config.xml
