• Hi,

I don't understand how to use the regex search and replace. Perhaps an example will help me get the hang of it:

I have a text file with sequences of characters like

{\bf “The Dervish Lodge: Architecture, Art, and Sufism in Ottoman Turkey.”}

I would like to search for

\{\\bf “(.*?)”\}

and replace with

\index{\bf $1} where '$1' represents what's in parens

basically I want to get rid of the quotes and index what's in brackets. How do I do this using the regex dialog?

Best

Try this

search
\{(\\bf) "(.*)"\}

replace
\index{\1 \2}

Basically - Take the "?" out -- and use \1 instead of \$1 to reference

(I used ()'s around the \bf - because i was having trouble with the \b in the replace adding a BS instead of "\b")

• Hi,

Thank you: the following works in my case:

search
\{(\\bf) “(.*)”\}

replace
\index{\1 \2}

The only difference being the kind of quotes used in my specific case.

If I am understanding correctly, the '\' is an escape character in the Replace dialog and everything else is treated as text. Are there any other escape characters for the replace? (I think I understand the search side of regex's better than I get the rules for the replace side).

THNX: I really appreciate it!

When trying to solve this regex problem -- I tried using an extra "\&quot; in the replace to 'escape' the "\&quot; before the "b" in the replace -- (\index{\\bf \1} -- but it still translated the \b into a BS resulting in "\index(\BSf <text>)

(Where BS = special character (backspace I think?)

Does anyone know how you could insert a literal "\b" into a replace, without tagging "\b" from the search, and just refferencing it in the replace? Basically, if "\b" was not in the original text -- how could I insert it, in a regex search/replace?

• That's a great help, did not see that one before...
