WebVerifyTable Function


Parses HTML tables and compares its cell content with the provided string. If it does not match, an error is raised. The severity of this error can be specified. The verification result can be retrieved by an optional out-parameter. A subsequent low-level function will not return a value until the request has finished.

When verifying/parsing an HTML page that consists of multiple frames, you can specify which frame document to verify/parse by specifying the sFrame parameter. By default, all HTML documents of the HTML page are scanned. This applies to HTML pages that are retrieved through a page-level command like WebPageUrl or WebPageLink.

It is important to know that all parsing and verification functions must be specified before the Web API call for which the response data should be parsed/verified. You can specify multiple parse/verification functions before a Web API call. The order of the parse/verification functions is not relevant (Exception: WebParseDataBound and WebVerifyDataBound using the flag WEB_FLAG_SYNCHRON).

This verification feature can be enabled/disabled globally (Profile Settings / Web / Verification / HTML / Table verification).

Note: This function can be added automatically to your script using the visual verification functionality of TrueLog Explorer.

Parameter Description
nTableNum The nTableNum th table is checked.
nRow Specifies the row of the cell to verify.
nColumn Specifies the column of the cell to verify.
sVerify String to compare with the parsed cell.


The actual parsed table cell must contain the specified string. Otherwise the verification fails.
The actual parsed table cell must not contain the specified string. Otherwise the verification fails.
The actual parsed table cell must not be equal to the specified string. Otherwise the verification fails.
The actual parsed table cell must be equal to the specified string. Otherwise the verification fails. If none of the above 3 flags are specified, the WEB_FLAG_EQUAL flag is used.
If this flag is set the string compare operation is case sensitive.
If this flag is set all white spaces are ignored.
Specify this option to enable caching for subsequent request. Note that this may lead to unpredictable behaviour, because the verification may only cover certain parts (that are loaded) of a page.
sFrame Frame that gets searched for the specified table (optional). If this parameter is omitted the whole page is scanned.
nSeverity Optional: Severity of the error that is raised if the verification fails. Can be one of the following values:
  • SEVERITY_SUCCESS: Success; no error (numerical value: 0)
  • SEVERITY_INFORMATIONAL: Informational; no error (numerical value: 1)
  • SEVERITY_WARNING: Warning; no error (numerical value: 2)
  • SEVERITY_ERROR: (Default) Error; simulation continues (numerical value: 3)
  • SEVERITY_TRANS_EXIT: Error; the active transaction is aborted (numerical value: 4)
  • SEVERITY_PROCESS_EXIT: Error; the simulation is aborted (numerical value: 5)
bSuccess If a variable is provided, it will receive the result of the verification (optional).
