Awk: search and replace

I have a file which requires modification via a shell script.

Need to do the following: 0. take input from user for new text. 1. search for a keyword in the file. 2. going forward, search for another keyword. 3. Replace this line with user supplied input.

for e.g., my file has the following text:

Code:
(some text)
(some text)
(text1_to_search)
(some text)
(text2_to_search_and_replace)
(some text)
(some text)

I need to search the file for a keyword and rewrite the file replace the matching the next search line with the input to this script leaving the remaining content untouched.

Regards
