Select text on first line AND another text on third line by regexp

Question

Suppose I has 2 jsons:

{                                                                                                                                                                                                                                            
    "action": "Handler:GET_DICTIONARY",
    "locale": "en",
    "data": {"dictionary_type":"EXCHANGE_RATES_AS_DICTIONARY"}
}

and

{                                                                                                                                                                                                                                            
    "action": "Handler:GET_DICTIONARY",
    "locale": "en",
    "data": {"dictionary_type":"MTS"}
}

I need to select only second json by regexp. The unique text to identify second json are: on first line: GET_DICTIONARY

AND on third line:

MTS

What is a correct regexp for this?

I try this regexp but it not help:

"GET_DIRCTIONARY C-q C-j
MTS"

Answer 1

The following input for re-search-forward will do:

GET_DICTIONARY\(.* C-q C-j \)\{2\}.*MTS

The parenthesis \( and \) define a group that is exactly two times repeated by \{2\}. The content of the group is a sequence of arbitrary many non-newline characters .* and a newline that is input with C-q C-j.

After the last newline the group is followed by arbitrary many non-newline-characters .* and then by MTS.

Your main errors were

1. that you didn't admit for the non-newline characters and
2. that you did only admit one newline.

The basic elements for regexps are described in the Emacs manual.
