我的代码受Search and replace a line in a file in Python
启发from tempfile import mkstemp
from shutil import move
from os import remove, close
def replace(file_path, pattern, subst):
#Create temp file
fh, abs_path = mkstemp()
with open(abs_path,'w') as new_file:
with open(file_path) as old_file:
for line in old_file:
new_file.write(line.replace(pattern, subst))
close(fh)
#Remove original file
remove(file_path)
#Move new file
move(abs_path, file_path)
replace("c:\\temp\\stack_add_ext_input.xml","<Bins","<ext:Bins")
replace("c:\\temp\\stack_add_ext_input.xml","/Bins>","/ext:Bins>")
#wont work with this method
#replace("c:\\temp\\stack_add_ext_input.xml","<Bin","<ext:Bin")
#replace("c:\\temp\\stack_add_ext_input.xml","/Bin>","/ext:Bin>")
#wont work with this method
replace("c:\\temp\\stack_add_ext_input.xml","<Plays","<ext:Plays")
replace("c:\\temp\\stack_add_ext_input.xml","/Plays>","/ext:Plays>")
然而，这不会起作用，因为我有Bins，Bin＆gt;，Plays，Play标签 有更简单的方法吗？ 我尝试在python中使用XML相关的包但我无法轻松地使用现有的package.method找到一种方法...
我正在考虑实现状态机以在读取文件行时跟踪状态。 但它似乎有点过分....
