Namespace: Facilita.WebAssembly: clrWebBrowser (in clrWebBrowser.dll) Version: 9.5.7.98 (1.0.0.0)
Syntax
public string Extract( List<string> before, string after, ActionType failAction )
Parameters
- before
- Type: System.Collections.Generic List String
Each string in this List is searched for sequentially in the response content, and the returned string starts immediately after all the string objects have been matched in the content.
- after
- Type: System String
This text is searched for in the response content after the before text has been found, and the returned string ends immediately before this text occurs in the content.
- failAction
- Type: Facilita.Fc.Runtime ActionType
The action to take if the text cannot be found.
Return Value
The extracted text, or an empty string if the extract failed.Remarks
Note |
---|
The search is case-sensitive. |
Supplying a List<string> of before values enables you to express more complicated extraction patterns. eggPlant Performance searches for the first string in the list, and searches for the second string after the position at which the first string was found. This continues until the final string is matched, after which the extracted response content is returned until after is matched. See the example below, in which a known unique name (f_custid) is used to narrow the search.
Examples
Response response = request.Send(); // extract the f_custid value from the HTML text // <input type="text" name="f_customer" size="32" maxlength="32" value="Joe Smith"> // <input type="text" name="f_custid" size="10" maxlength="10" value="12345"> // <input type="text" name="f_account" size="10" maxlength="10" value="9876543"> List<string> before = new List<string>(); before.Add("f_custid"); before.Add("value=\""); string extractedText = response.Extract( before, "\"", ActionType.ACT_WARNING);
