| 标题 | Python实现删除Android工程中的冗余字符串 |
| 范文 | 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") else: return (basicLanguage + '/strings.xml', filePath + "/strings.xml") return None def genLangPair(filePath): def shouldGenLanPair(filePath): if (not 'values' in filePath ): return False if('dpi' in filePath): return False if ('dimes' in filePath): return False if ('large' in filePath): return False return True if(shouldGenLanPair(filePath)): basicLanguage = path.dirname(filePath) + '/values/strings.xml' targetLanguage = 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 |
