Regex to search at beginning of line - Page 2

Wow! Really working without problem! Many, many thanks! The book looks pretty much better now!

Leonatus · 05-31-2013, 03:28 PM

Hm, becoming quite bold, there's another book with a similar problem, only that the, for example, [Pg 6] terms are embedded in only "normal" span tags, such as [Pg 6], viz. without a specific tag. How can I remove them without interferring other "normal" span tags?

Try search of

Code:

<span>\[Pg\s\d+\]</span>

replace with empty
the \[ means include a [ char - needs to be escaped
the \s means whitespace
the \d+ means one or more digit

I dislike overly wild S&R terms. Yours will only match what is desired

Great! I find regex a fascinating materia, and after getting such shorthanded, well-working advice, I wonder how I can be trying so many times, ever committing some mistake. How can one study this (the introduction in mobile read is really short for absolute beginners)?

Check out this German website.

I regularly referred to http://www.regular-expressions.info/ when first learning. Very good for pointing out the differences in the various flavors of Regex.

Would the following regex work in Sigil?

\[Pg [0-9]*\]

That works in Notepad++.

It would work BUT
It would also match Zero digits (because you used * instead of +) and may leave a orphaned roman series with out the Pg that gave the clue of what it was. Yeah, I know romans are few and far between, but I prefer best practices

Ducky, heart of my heart:

Maybe we should consider a sub-forum to the Regex examples sub-forum for Regex questions? Not snarking, but it might seem to be a sensible place to put it. Just a thought. That way, other people searching for regex answers might be able to look in two places--the regex examples and the regex questions--which might be helpful.

Doh!
We have a REGEX Sticky.

Why these new threads get started, I have no clue (Actually I do

: Monster threads are a pain to look through )

Maybe we need to start posting the examples to the Wiki and pointing people to it instead of a thread or threads?

I know we have a regex sticky; that's kind of what I was thinking. I mean...the regex sticky, to me, anyway, looks like regex examples from people who know what they are talking about. Right? I mean, if I had a question, I wouldn't ask there, if that makes sense. Examples, not questions. (Does that make sense to anyone else?)

Well, that's not a bad idea. Maybe group regex by type, or by goal? I'm honestly not complaining about the regex threads, I'm just thinking, if people could have a "one-stop shop," it would be genuinely helpful. Just my $.02. And we all know that there is some mighty, mighty regex-fu available amongst MR'ers, that would be an invaluable resource (hell, I'd like to have a regex research resource my own damn self, as my regex-fu is weak).

Actually, I think a regex forum would be a good thing to have.

Sorry for my monster thread! But I would not have thought that the sticky thread would be for absolute beginners like me.

A special subforum would, however, really useful.

Edit: Be useful, of course.
