python参数，既有单引号又有双引号的解决办法：
使用双引号引起来，中间的双引号使用\转义，中间的单引号不转义，如下
python3 ./pluginTool.py out/228out/tr069Transform_ass.xml tr069Transform_ass modify /tr069Transform_ass:Device/tr069Transform_ass:Services/tr069Transform_ass:FAPService/tr069Transform_ass:CellConfig/tr069Transform_ass:NR/tr069Transform_ass:NGC/tr069Transform_ass:TA/tr069Transform_ass:TAC "{\"Trans\":true,\"Notification\":2,\"AccessList\":[\"Subscriber\"],\"Shell\":\"./scripts/TAC_Convert\",\"Links\":[{\"Xpath\":\"/duoam:InternetGatewayDevice/Services/FAPService[name='3333']/CellConfig/FIVEGNR/RAN/CommonInfo/FIVEGSTAC\",\"Config\":true}]}"
