Multiple languages need to be added to the project. Android character files are all put in. xml, which is well organized. iOS only needs to convert xml files into OC string files to use
Using Python 3 to write a script, you can modify the xml file and OC file, and then automatically read and write the xml file to OC file

• This demo is not perfect enough. At present, only one language can be written at a time. It will be improved later if there is demand

• In the project, xmltodict is used to read XML. The installation of xmltodict is very simple. You only need to input one line of command in the command line

  pip3 install xmltodict

Because Python 3 is used, pip3 is used. If Python 2 is used, pip can be used directly

Main project code
Read XML

def readXML(path):
    ocString = []
    with open(path) as fd:

        obj = xmltodict.parse(fd.read())
        resources =  obj["resources"]
        strings = resources["string"]
        nameKey = "@name"
        valueKey = "#text"
        for item in strings:
            value = ""
            key = ""
            for k, v in item.items():
                if k == nameKey:
                    key = v
                if k == valueKey:
                    value = v


            singleStr = "\""+key + "\"" + " = " + "\"" + value + "\"" + ";" + "\n"
            ocString.append(singleStr)
    return ocString

Write in

def writeFileWithList(lines, filePath):
    with open(filePath, 'a') as f:
        for itme in lines:
            f.write(itme)
