我需要读取一个plist文件并搜索一个字符串,然后在下一行添加一行新文本。我无法想象这样做会花费很多。然而,plist是二进制格式,所以不确定如何处理它。

#Convert plist to XML
os.system('plutil -convert xml1 com.apple.iChat.Jabber.plist')
AutoDiscovery = "<integer>0<integer>"
import fileinput
for line in fileinput.FileInput("com.apple.iChat.Jabber.plist",inplace=1):
line = line.replace("<key>AutoDiscoverHostAndPort</key>",AutoDiscovery)
print line,
#Concert plist to binary file
os.system('plutil -convert binary1 com.apple.iChat.Jabber.plist')

您希望首先将其转换为xml格式:
plutil -convert xml file.plist
其余的应该相当容易。
编辑:
newFile = open('file.copy', 'w+')
for line in open('file'):
if (line.find('string_to_find') >= 0):
# do something with "line"
newFile.write(line)
newFile.close()
EDIT2:
# convert plist from binary to xml
plist = plistlib.readPlist('your.plist')
plist['key'] = 0
plistlib.writePlist('your.plist')
# convert plist from xml to binary

使用plistlib
来满足您的所有plist文件需求。无需转换。
