iOS开发后台请求报错,帮忙看下XML格式哪里有问题 急急急!!!大神们

报错:Entity: line 1: parser error : Start tag expected, '<' not found
以下为请求XML,用的是ASIHTTPRequest请求框架,不知错在何处
<?xml version='1.0' encoding='UTF-8' standalone='yes'?><Root><method action="E"><classPath>com.portal.android.ExecuteAndroid</classPath><methodName>changeState</methodName></method><kvdata ID="" SHIP_NAME="ceshi01" CARGO_REMARK="种用硬粒小麦100111009012吨" DOCK="E201205160096297" BERTH="E201205160096300" CARGO_TYPE="0" CARGO_NAME="种用硬粒小麦" CARGO_HS_CODE="1001110090" CARGO_WEIGHT="12" BILL_INFO="" MANIFEST_INFO="" CLIENT="" ISDECL="NODECL" CREATE_ORG="江阴市外轮代理有限公司" CREATE_ORG_ID="201307220000013086" CREATE_USER_ID="201306030000007077" CREATE_USER="杨柳絮" UPDATE_USER_ID="201306030000007077" UPDATE_USER="杨柳絮" AGENTID="E201511120021555"></kvdata></Root>

由于把请求数据加密了,请求回调时处理数据未解密,所以导致了错误

格式没错哦,你用一个支持xml的ide打开一下就可以知道有没有语法错误。。。

请求数据是不是有错误?
能不能把你打印请求数据的代码贴出来
