标题: lr_xml_set_values函数取值问题
基本信息：lr版本：9.5
      协议：http/html

"<employee>John</employee>"
"<cubicle>227</cubicle>"
"<app>227</app>"
"<test>227</test>"
"</acme_org>";
int find_cnt;
//int OutputParam;

lr_save_string(xml_input, "XML_Input_Param");
find_cnt = lr_xml_find("XML={XML_Input_Param}",
  "Value=John",
  "Query=/acme_org/employee",
  LAST );

if (find_cnt >0)
      {
lr_xml_insert("XML={XML_Input_Param}", "ResultParam=Result",
               "XmlFragment=<extension>2145</extension>",

                  "ValueParam=ExtensionParam",
                  "SelectAll=yes",

               "Query=//test",
               "ValueParam=Result",
               "SelectAll=yes",
               "NotFound=continue",

疑问：1、为什么传参的时候名字是ExtensionParam、而变量赋值的时候名字是ExtensionParam_1 如果两个处的名字相同替换的内容就自动加上“_1”
      2、如果lr的修改xml文件内容的要求就是两处名称不一样，那么当有多个参数传参的时候如何处理。
      3、脚本中最后一段代码的目的是想输入test标签修改后的值。但输出的信息还是修改前的值。（此处有可能是我代码写的不对，如果有人事先了请告诉我一下）
