Limiting the Display of Search Results--Regular Expressions

Postby rcbenjamin » Wed Jul 29, 2015 5:35 am

How can I get the search options to display only the verses that has 5 or more words in italics. I am using
<i>\w+</i> to display all italics.

Reg Exes are very powerful pattern matching tools, but they can be a little difficult to learn.

Here are some examples in finding italicized words in Bible Analyzer 5:

<i>.+?</i> finds all words in a row from one to infinity.
<i>\w+</i> finds only a single word
<i>\w+(\s\w+){1}</i> finds only a set number of words separated by a space. Here it will find two.
<i>\w+(\s\w+){2}</i> finds three words. (The {2} multiplies only what is in parenthesis, here a space and word string.)

Translate above:
<i> = starting italics tag
.+? = at least one character (? = non-greedy search, so it won't go past the closing tag)
\w+ = at least one word character (a-z)
\s = space character
{2} = multiplier
</i> = closing tag

The above will find italic words together. A little more elaborate method is required to find scattered italicized words.

<i>\w+</i>.+?<i>\w+</i>.+?<i>\w+</i>.+?<i>\w+</i>.+?<i>\w+</i>
or for the multiplier version
<i>\w+</i>(.+?<i>\w+</i>){4}
finds 5 words in a single verse. Note, this reg ex will select or highlight the entire span, not just the italicized words. Reg Exes treat the found string as one unit.

An even shorter alternate method
(<i>\w+</i>)(.+?\1){4}
will not work in Bible Analyzer because of the \1 back reference. (BA uses those internally and putting one in a search causes a conflict)

Thank you. Why doesn't <i>\w+</i> or any of the expressions you mention find the italics in 1John 2:23 in the AV version

<i>.+?</i> finds it.

Those that have only "\w" in them will not because the parenthesis in the verse are not word characters and must be accounted for in the Reg Ex. A dot (.) represents any character.

<i>.+?</i> does find 1John 2:23 but how can I now combine it with other expressions so that the verse in 1John 2:23 is found with all of the other verses that also have more than 5 words that are in italics?

This might not be 100% It isn't as easy as it seems to do these type of searches. So the below should get 5 words, 4 plus the one next to the </i>
<i>(?:[^< ]+ ){4,}[^<]+</i>

Thanks for your assistance but the expressions need to be modified because in Lev 17:15 it does not mark "of itself" or "himself" in italics. It only marks the phrase "with beasts, whether it be" which is correct but what I wanted was a total count of 5 more words in italics in a single verse regardless of the words being grouped together in a phrase or separated with several spaces, words or punctuations marks between them.

I think that would need to be done programmatically.
