I'm not sure I undersand the input formats right.

Input: You have aline which contains a title followed by one or more lines which contain one or more item numbers per line. A title starts allways on a new line consists of a string and ends with a ID (char with a number) included in parentesis. Items always start with ID which consists of (capital) characters, numbers followed by space followed by a string.

Output: A title should start on a new line, it should be followed by a semicolon, followed by an item. this should be repeated for all items till new title starts. the output of you data should be: 

Titel Text (A12-3);3-123.7 Just another text 
Titel Text (A12-3);3-123.8 Some more text
Titel Text (A12-3);A12.34 Another item
Titel Text (A12-3);B56.78 Yet another item
Another Titel Text (B23-9);1-22a.b Just another text 
Another Titel Text (B23-9);2-3cd.e Some more text
Another Titel Text (B23-9);W12.34 Another item 
Another Titel Text (B23-9);Z56.78 Yet another item
