Regex for next "n" characters

mrmikel · 10-02-2014, 02:18 PM

I use h3 for headers for chapters. I would like to be able to make an id using regex.

I would like to take the next 5-7 characters out of the heading following <h3> and make it <h3 id="next5characters">. I suppose I could rename all the chapters so I could make an HTML TOC more easily, but this seems less work, if it can be made to work.

Thanks.

You can match any character with the dot, and use

Code:

.....

to match any five characters.

You can also use

Code:

.{5}

to repeat the preceding character/group 5 times. See: http://www.regular-expressions.info/repeat.html under "Limiting Repetition".

Code fragment:

Code:

(\S){2,5}

I chose the range: 2 thru 5 of not whitespace

You would need to do the rest

It works out fine as

Find <h3>(.....)

Replace <h3 id="\1">\1

What if there's a space in the first five characters? Can't have spaces in id attribute values. And aren't the first five letters often "chapt" ?

In the particular one I was working on, neither was the case. I suppose in that case it would be simpler with chapter [1-9].... or something on that order. Fortunately they are not all like the one I was doing which is more like a pamphlet than a book.
