Android提供了一套很方便的进行资源（语言）国际化机制，为了更好地支持多语言，很多工程的翻译往往会放到类似crowdin这样的平台上。资源是全了，但是还是会有一些问题。

哪些问题

以下使用一些语言进行举例。其中values为工程默认的资源。

1.某语言的资源和某语言限定区域的资源之间。如values-fr-rCA存在于values-fr相同的字符串，这种表现最为严重。

2.某语言的资源和默认的资源之间。values-fr存在与values相同的字符串，可能原因是由于values-fr存在未翻译字符串导致

为什么要去重

洁癖，容不下半点冗余。

解决思路

1.如果values-fr-rCA存在于values-fr相同的字符串，去除values-fr-rCA中的重复字符串，保留values-fr。这样可以保证在values-fr-rCA下也可以正确读取到资源。

2.如果values-fr存在与values相同的字符串。如去除values-fr中得重复字符串，保留values的条目。

Py脚本

代码如下:

#!/usr/bin/env python

# coding=utf-8

from os import listdir,path, system

from sys import argv

try:

import xml.etree.cElementTree as ET

except ImportError:

import xml.etree.ElementTree as ET

def genRegionLangPair(filePath):

basicLanguage = None

if ('values' in filePath) :

hasRegionLimit = ('r' == filePath[-3:-2])

if (hasRegionLimit):

basicLanguage = filePath[0:-4]

if (not path.exists(basicLanguage)) :

return None

belongsToEnglish = ("values-en" in basicLanguage)

if (belongsToEnglish):

#Compare with the res/values/strings.xml

return (path.dirname(basicLanguage) + '/values/strings.xml', filePath + "/strings.xml")

if (not path.exists(targetLanguage)):

return None

if (not path.samefile(basicLanguage,targetLanguage)) :

return (basicLanguage, targetLanguage)

return None

def genCompareList(filePath):

compareLists = []

for file in listdir(filePath):

regionPair = genRegionLangPair(filePath + '/' + file)

if (None != regionPair):

compareLists.append(regionPair)

languagePair = genLangPair(filePath + '/' + file)

if (None != languagePair) :

compareLists.append(languagePair)

return compareLists

def getXmlEntries(filePath):

root = ET.ElementTree(file=filePath).getroot()

entries = {}

for child in root:

attrib = child.attrib

if (None != attrib) :

entries[attrib.get('name')] = child.text

print 'xmlEntriesCount',len(entries)

return entries

def rewriteRegionFile(sourceEntries, filePath):

if (not path.exists(filePath)):

return

ET.register_namespace('xliff',"urn:oasis:names:tc:xliff:document:1.2")

tree = ET.ElementTree(file=filePath)

root = tree.getroot()

print root

totalCount = 0

removeCount = 0

unRemoveCount = 0

print len(root)

toRemoveList = []

for child in root:

totalCount = totalCount + 1

attrib = child.attrib

if (None == attrib):

continue

childName = attrib.get('name')

if (sourceEntries.get(childName) == child.text):

removeCount = removeCount + 1

toRemoveList.append(child)

else:

unRemoveCount = unRemoveCount + 1

print childName, sourceEntries.get(childName), child.text

print filePath,totalCount, removeCount,unRemoveCount

for aItem in toRemoveList:

root.remove(aItem)

if (len(root) != 0 ):

tree.write(filePath, encoding="UTF-8")

else:

command = 'rm -rf %s'%(path.dirname(filePath))

print command

system(command)

def main(projectDir):

lists = genCompareList(projectDir + "/res/")

for item in lists:

print item

src = item[0]

dest = item[1]

rewriteRegionFile(getXmlEntries(src),dest)

if __name__ == "__main__":

if (len(argv) == 2) :

main(argv[1])

如何使用

代码如下:

python removeRepeatedStrings.py your_android_project_root_dir
