三、例子

Example 1

In the following example, web_reg_find function searches for the text string "Welcome". If the string is not found, it fails and the script execution stops.

web_reg_find("Text=Welcome", LAST);

web_url("Step", "URL=...", LAST);

Example 2

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

web_reg_find("Text/IC=Error", "Fail=Found", LAST);

web_url("Step", "URL=...", LAST);

Example 3

In the following example, web_reg_find function 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=ABC", "SaveCount=abc_count", LAST);

web_url("Step", "URL=...", LAST);

if (strcmp(lr_eval_string("{abc_count}"), "0") == 0)

Action A

else

Action B

Example 4

In the following example, an ID argument "XYZ" associates the call to web_reg_find with a line in the log file. If you have to look for the entry in the log file that logged the call to web_reg_find, searching for the string "XYZ" will make it much easier.

web_reg_find("Text=mitcham", ID=XYZ", LAST);
web_url("web_url", "URL=http://lazarus/", "TargetFrame=",
          "Resource=0", "Referer=", LAST);

The entries in the log file will be one of the following, depending on whether the web_reg_find succeeded in finding the text "mitcham" was found:

Action1.c(12): Matched web_reg_find with "Fail=NotFound" ("XYZ"). Text "mitcham" (count=78)

Action1.c(10): Error: No match for web_reg_find with "Fail=NotFound" ("XYZ"). Text "mitcham"
