In this example, web.reg_find checks for the login name. Commented out, is an alternative example of how to use the function to look for leading and trailing strings.

{
    // Run the Web Tours sample program
    web.url("WebTours",
        "URL=http://localhost/WebTours/",
        new String[]{
            "Resource=0",
            "RecContentType=text/html",
            "Referer=",
            "Mode=HTML",
            web.LAST
        });

    /* In a real script, you will probably use parameterization
    for LoginName. For this example, we simply create one parameter.
    */

        lr.save_string("jojo" , "LoginName" ); 

    // Set up check for successful login by looking for the login name

    web.reg_find("Text=<LoginName>",
        new String[]{
            "SaveCount=WelcomeCount",
            web.LAST
        });

/*      ******** Alternative ************
An alternative check which does not require knowing the login name, is to look for the strings that precede and follow the login name when the login is successful.

    web.reg_find("Text=",
        new String[]{
            "TextPfx=Welcome,",
            "TextSfx=, to Web Tours",
            "SaveCount=WelcomeCount",
            web.LAST
        });

*************************************/

// Now log in
    web.submit_form("login.pl",
        new String[]{},
        new String[]{
            "Name=username", "Value=<LoginName>", web.ENDITEM,
            "Name=password", "Value=bean", web.ENDITEM,
            "Name=login.x", "Value=35", web.ENDITEM,
            "Name=login.y", "Value=14", web.ENDITEM,
            web.LAST
        });

    /* Check the Welcome Count and take whatever actions are
        appropriate for your script */

    if (lr.eval_int("<WelcomeCount>") == 0 )
        lr.message("Login " + lr.eval_string("<LoginName>") + " unsuccessful");
    else
        lr.message("Login " + lr.eval_string("<LoginName>") + " successful");
}
catch (Exception e){}

In the following example, reg_find searches for the text string "Error." If the string is found, it fails and the script execution stops.

web.reg_find("Text/IC=Welcome", 
    new String []{Fail=Found", "LAST"});
web.url("test1.html",
    "URL=http://localhost/test1.html",
     new String []{"LAST"});

In the following example, reg_find searches for the text string "ABC". If the string is not found, the script executes Action A. If the string is found one or more times, it executes Action B.

web.reg_find("Text/IC=ABC", 
    new String []{"SaveCount=abc_count", "LAST"});

web.url("test1.html",
    "URL=http://localhost/test1.html",
     new String []{"LAST"});

lr.message("Value of abc_count is " + lr.eval_string("<abc_count>"));

if (lr.eval_int("<abc_count>") == 0)
      lr.message("Not Found");
else
      lr.message("Found");
