Insert/replace text after a known paragrapher.

[Adriano Borgobello]

In a plain text file, how can I replace or insert a string at the starting of a paragraph, knowing a substring in the previous paragraph?!

I try to explain with an example.

I have hundreds of paragraphs that start with the substring "¶Art. " and continues with different text. I need to insert a new substring "¶_A" at the head of all paragraphs that follows the above, but only at the first (there are undefined number of paragraphs after each "¶Art. " starting paragraph.

I say insert or replace, because I guess I can replace newline char with newline + "¶_A".

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.

Hope this helps,

Thanks, but won't work be me. Instead this does the job and something more (it's not from my skill, but I'm trying to understand it):

Search: ¶([ASCT])([^ ]+ [0-9IVXLC]+)( |\n)

Replace: ¶\1\2\n¶\1_
