Regex F&R problem?

Jabby · 06-10-2012, 07:36 AM

I had noticed in the past that the regex count and replace numbers didn't always match and decided to look into it.

The reason for this disparity is that the count notes each instance of the regex match while the replace function replaces only the first match in any given paragraph. Ergo, the count difference. This is not true for a "normal" F&R.

No big problem if you are aware of this anomaly. Just re-run the F&R until none are replaced.

I hope this isn't old hat but I haven't seen anything on it and a search didn't turn up anything.

It's possible that the regular expression that you used caused the problem and not Sigil. Can you give us examples of specific regular search expressions that you used and the texts that you used it with?

First things first. This is an amended version the first paragraph of my original post which should read:

I had noticed in the past that the normal count and regex count numbers didn't always match and decided to look into it.

Using the attached file, count the number of calibre9 and you will get of 120. The same with <em class="calibre9">. Using the regex terms below you will get a count and a replace count of 90.

Code:

<em class="calibre9">(.*)</em>
<span class="italic">\1</span>

Execute another replace using the same terms same and you wiil get a count of 18. At this point 108 changes have been made.

Go to line 102 of chapter 12 and you will find five instances of the terms in question. The first two have been changed the remaining three remain the same.

Try:

Find:

Code:

<em class="calibre9">(.*?)</em>

or

Code:

(?U)<em class="calibre9">(.*)</em>

Ah so!

As the old Yiddish (maybe) saying goes, "too soon old, too late smart".

FWIW--I believe that's actually Amish. I could be misremembering--those ol' brain cells aren't firing on all the cylinders as they did when erewhile I was young; but, I think that's right. ;-)
