Something like this should do the trick. The expression in the first set parentheses finds the paragraphs you are targeting. The start of a line ^ followed by your target text and everything up to the next new-line \n. The expression in the second set of parentheses finds the following paragraph. The replacement pattern inserts the new text you need between them so it prefixes the second paragraph.
Search: (^Art\..*?\n+)(.*?$) Replace: \1_A\2 Art. One First paragraph Second paragraph Art. Two First paragraph Second paragraph Becomes Art. One _AFirst paragraph Second paragraph Art. Two _AFirst paragraph Second paragraph The Pattern Playground on the Search menu is pretty useful for playing around with these expressions.
