Response Extract Method (List String , String)C# API
Extracts text from the response content - everything between (but not including) the specified list of before and after string objects - returning an empty string if they cannot be found.

Namespace: Facilita.Web
Assembly: clrWebBrowser (in clrWebBrowser.dll) Version: 9.4.0.26 (1.0.0.0)
Syntax

public string Extract(
	List<string> before,
	string after
)

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.

Return Value

The extracted text, or an empty string if the extract failed.
Remarks

Note 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

The following example demonstrates using a list of strings to narrow down the search for text to extract from a HTML Response.
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,
                        "\"");
