#in here inputPath is jinja templates path
for root, dirs, files in os.walk(inputPath):
    for file in files:
        fPath = root[len(inputPath) + 1:]
        newPath = (fPath + "/" if fPath else '') + file
        template = env.get_template(newPath)
        oPath = os.path.join(outputPath, fPath)
        try:
            os.makedirs(oPath)
        except:
            pass
        oPath=os.path.join(oPath,file)
        with codecs.open(oPath,'w', "utf-8") as f:
            f.write(template.render(projectname=projectName, mainxmlpath=mainXamlPath))
