获取不到服务器返回的SessionID

hy286

用的是LoadRunner9.0，协议采用的是Web Services，测试时导入了相应的wsdl文件
脚本如下，灰色部分为次要内容，只是为了方便看得更清楚
     web_add_auto_header("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; MS Web Services Client Protocol 2.0.50727.42)");
    web_add_header("Content-Type", "text/xml; charset=utf-8");
    web_add_header("SOAPAction", "\"xjuuaclientAppLogin\"");
   
    web_reg_save_param("RETURNSESSIONID",
                                        "LB=<xjuuaclientAppLoginReturn>",
                                        "RB=</xjuuaclientAppLoginReturn>",
                                        "ORD=1",
                                        LAST);

    soap_request("StepName=xjuuaclientAppLogin",

                "<xjuuaclientAppLogin xmlns=\"http://"

                ">10.72.27.29</ipAddress><processFlag xmlns=\"\">2009-05-04 18:14:49 "

                "Snapshot=t2.inf",
                "ResponseParam=response",
                LAST);
   lr_log_message("getvalue : %s",lr_eval_string("{RETURNSESSIONID}"));
  web_add_auto_header("SOAPAction", "\"writeOperationLog\"");
   web_add_header("Content-Type", "text/xml; charset=utf-8");
   return 0;

RETURNSESSIONID参数化时，参数类型选为File

日志中返回结果如下

在日志中可以看到返回的SessionID为136133920090507$10143688545，但RETURNSESSIONID参数却读不到这个数据，而且出错后也不允许进行多次迭代了,不知道问题出在哪里？
各位帮忙看看吧。

建议设置参数 的长度， 另外把所有请求放在action()里。
不知道是什么样的结构，试试http协议吧
