Hi Guys,
Can someone help me with a way to extract text between two words on a single line.
For example if the file has below content I want to extract all text between b and f inclusive of b and f. Aparently sed does this but does it line by line and I guess it cannot read word by word.

pdo.sqlitecreatefunction
PDO.SQLITECREATEFUNCTION(3) 1 PDO.SQLITECREATEFUNCTION(3)PDO ::sqliteCreateFunction - Registers a User Defined Function for use in SQL statements
SYNOPSIS
public bool PDO::sqliteCreateFunction (string $function_name, callable $callback, [int $num_args])
DESCRIPTION
Warning
This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in
a future release of PHP. This function should be used at your own risk.
This method allows you to register a PHP function with SQLite as an UDF (User Defined Function), so that it can be called from within your
SQL statements.
The UDF can be used in any SQL statement that can call functions, such as SELECT and UPDATE statements and also in triggers.
PARAMETERS
o $function_name
- The name of the function used in SQL statements.
o $callback
- Callback function to handle the defined SQL function.
Note
Callback functions should return a type understood by SQLite (i.e. scalar type).
o $num_args
- Hint to the SQLite parser if the callback function accepts a predetermined number of arguments.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
PDO.sqliteCreateFunction(3) example
<?php
function md5_and_reverse($string)
{
return strrev(md5($string));
}
$db = new PDO('sqlite:sqlitedb');
$db->sqliteCreateFunction('md5rev', 'md5_and_reverse', 1);
$rows = $db->query('SELECT md5rev(filename) FROM files')->fetchAll();
?>
In this example, we have a function that calculates the md5 sum of a string, and then reverses it. When the SQL statement executes, it
returns the value of the filename transformed by our function. The data returned in $rows contains the processed result.
The beauty of this technique is that you do not need to process the result using a foreach loop after you have queried for the data.
Tip
You can use "PDO::sqliteCreateFunction" and "PDO::sqliteCreateAggregate" to override SQLite native SQL functions.
Note
This method is not available with the SQLite2 driver. Use the old style sqlite API for that instead.

"PDO::sqliteCreateAggregate", sqlite_create_function(3), sqlite_create_aggregate(3).
