修改文件报错问题

xml文件不断修改和插入数据的存取问题：报错

首先xml文件在修改后是要将整个文件写一次磁盘对吧(dom4j好像是这样的)?那如果一个大点儿xml文件,我读取它后再修改其中一个属性值,然后为了保存这次修改就要filewrite一次,好像不能"即改即存",那这个文件经常被修改,又或是这个文件比较大,那这样一次小修改代价岂不是很大? 还是我无知,并不是我上面所说的那样?请指教. 可能我表述的不准确,不知道我的意思大家能明白吗.

使用aliot_sdk_v1.0.1_release SDK,然后修改make.setting文件，PLATFORM_SSL = openssl 然后开始make，结果报错，如何修复这个问题？
