Notepad++ – Select whole line that contains a string with space

You can use ALT to select column, and next navigate to edit-> column editor in order to insert increasing numbers.

Using lookahead is much more efficient and can deal with any number of alternations without increasing complexity:

• Ctrl+F
• "Find what": ^(?=.*\b35=D\b)(?=.*\bEUR/USD\b)(?=.*\b150=8\b).+$
• Check "Match case"
• Check "Wrap around"
• Check "Regular expression"
• Uncheck ". matches newline"
• Find All in Current Document

Explanation:

^               # Beginning of line
  (?=           # Start positive lookaead, make sure we have after:
    .*          # 0 or more any character but newline
    \b          # Word boundary to be sure not matching 135=DATA
    35=D        # Literally
    \b          # word boundary
  )             # End lookahead
  (?=           # Start positive lookaead, make sure we have after:
    .*          # 0 or more any character but newline
    \b          # Word boundary
    EUR/USD     # Literally
    \b          # Word boundary
  )             # End lookahead
  (?=           # Start positive lookaead, make sure we have after:
    .*          # 0 or more any character but newline
    \b          # Word boundary
    150=8       # Literally
    \b          # Word boundary
  )             # End lookahead
  .+            # One or more any character but newline
$               # End of line
