Parses HTML tables and stores the content of the specified cell in the provided string. A subsequent low-level web 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).

Parameter | Description |
---|---|
sResult | String variable that receives the content of the specified cell. |
nMaxResultLen | Maximum length of the string to return. Set this parameter to STRING_COMPLETE all available data is stored in sResult. |
nTableNum | The nTableNum th table is parsed. |
nRow | Specifies the row of the cell to parse. |
nColumn | Specifies the column of the cell to parse. |
nOptions |
Parsing options (optional). If this flag is omitted, none of the listed options are applied, meaning that the string comparison is case-insensitive, white spaces are not ignored, etc.
|
sFrame | Frame that gets searched for the specified table (optional). If this parameter is omitted the whole page is scanned. |
nBytesParsed | Variable receiving the number of the bytes that actually parsed (optional). |
