Regexp that solves this ?

Regexp that solves this ?

[weber]

Hi folks.
I'd like to know if there is a simple way to replace regexp a file to
convert tables like this:

| name | value |
| x1   | 1001  |
| x2   | 2002  |

to this

|| name | value |
| x1   | 1001  |
| x2   | 2002  |

The problem is having a regexp that depends on the next line.

Ideas?

I don't really see what exactly you want to replace...
"| name" by "|| name" ? Probably not...

Well, this is no problem. Just type C-q C-j to get a newline in the
minibuffer.

Yes, exactly. I'm converting between org-mode tables and another
format (t2t) which uses similar tables.

Does the following works?

    (query-replace-regexp "^[[:space:]]*\n|[^|]" "\n||")

When calling `query-replace-regexp' interactively use "^Q^J" to input
a newline, instead of "\n" as above.
