LoadRunner函數詳解之web_reg_find

定義：在HTML頁面查詢指定的文本字符串
函數形式：web_reg_find( const char *attribute_list, LAST );

示例1：查詢字符串“Welcome”，如果該字符串未被查找到，則函數檢查失敗，腳本停止執行

    web_url("MercuryWebTours", 
        "URL=http://localhost/MercuryWebTours/", 
        "Resource=0", 
        "RecContentType=text/html", 
        "Referer=", 
        "Snapshot=t1.inf", 
        "Mode=HTML", 
        LAST ); 
    web_reg_find("Text=Welcome", 
        LAST ); 
    web_submit_form("login.pl", 
        "Snapshot=t2.inf", 
        ITEMDATA, 
        "Name=username", "Value=jojo", ENDITEM, 
        "Name=password", "Value=bean", ENDITEM, 
        "Name=login.x", "Value=35", ENDITEM, 
        "Name=login.y", "Value=14", ENDITEM, 
        LAST );

示例2：與示例1類似，但由於SaveCount參數被使用，因此腳本在檢查失敗時將繼續執行後續腳本

    web_url("MercuryWebTours", 
        "URL=http://localhost/MercuryWebTours/", 
        "Resource=0", 
        "RecContentType=text/html", 
        "Referer=", 
        "Snapshot=t1.inf", 
        "Mode=HTML", 
        LAST ); 

    web_reg_find("Text=Welcome", 
        "SaveCount=Welcome_Count", 
        LAST ); 

    web_submit_form("login.pl", 
        "Snapshot=t2.inf", 
        ITEMDATA, 
        "Name=username", "Value=jojo", ENDITEM, 
        "Name=password", "Value=bean", ENDITEM, 
        "Name=login.x", "Value=35", ENDITEM, 
        "Name=login.y", "Value=14", ENDITEM, 
        LAST ); 

    if (atoi(lr_eval_string("{Welcome_Count}")) > 0){ 
        lr_output_message("Log on successful."); 
        } 
     else{ 
        lr_error_message("Log on failed"); 
        return(0); 
     } 

示例3：查詢字符串“Error”，如果文本字符串被查找到，則函數檢查失敗，腳本停止執行。

web_reg_find("Text/IC=Error", "Fail=Found", LAST ); 
web_url("Step", "URL=...", LAST ); 

示例4：查找字符串“ABC”，如果文本字符串未被查找到，則腳本執行Action A；如果文本字符串被查找到1次或多次，則腳本執行Action B。

web_reg_find("Text=ABC", "SaveCount=abc_count", LAST ); 
web_url("Step", "URL=...", LAST ); 
if (strcmp(lr_eval_string("{abc_count}"), "0") == 0) 
Action A 
else 
Action B
