public virtual string ExtractFromEnd(
	List<string> after,
	string before,
	string defaultValue,
	bool caseSensitive,
	SearchFlags matchFlags
)

public virtual string ExtractFromEnd(
	List<string> after,
	string before,
	string defaultValue,
	bool caseSensitive,
	SearchFlags matchFlags
)

Parameters

after: 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 before all the string objects have been matched in the content.

before: Type: System String
This text is searched for in the response content after the after text has been found, and the returned string ends immediately after this text occurs in the content.

defaultValue: Type: System String
The value to return if either the before or after text cannot be found.

caseSensitive: Type: System Boolean
true if the search should be case-sensitive.

matchFlags: Type: Facilita.Web SearchFlags
An SearchFlags enumerated value to indicate what should be searched: SEARCH_IN_BODY, SEARCH_IN_HEADERS or SEARCH_IN_BOTH.

Return Value

The extracted text, or defaultValue if the extract failed.

Remarks

Supplying a List<string> of after 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 before is matched.
