Re: Regex Help

David-
Thanks, the regex you posted works great. I had considered just trimming the text inside the tags and then untrimming until a word end, but I figured there would be a regex that would do it all at once.

Thanks Dave-

Seems to me that you're trying to do too much with one regular expression. I

I'm not sure what you mean by "too much".  I think the substitution I
suggested does what Ezra said he needed.  Is there an error in it?

Hey Guys-
I have a regex problem that I am not sure how to tackle. I am parsing
some classified ads in order to format them for display online. I have

most

of the parsing done but I need help with the final step. So the file has

one

ad per line and a line looks like this:

<ftditm><begad:11559303>Selah Country Home 1.5 acres. 3 bdrm, 2 bath,
irrigation, horse barn. $122,000. 509-697-6519<endad>

Now I have already parsed everything to get it to this state but what I
need to do next is to count 50 chars after the <begad:11559303> tag and
insert </ftditm>
But the tricky part is that I need to place the </ftditm> 50 characters

in to

the line but if the 50 chars ends in the middle of a word then I need to
match the rest of the word as well. So I need a way to match at least 50
chars plus the rest of the current word if the 50'th char lands in the

middle

of a word.
So for this particular ad 50 chars makes it to here:
<ftditm><begad:11559303>Selah Country Home 1.5 acres. 3 bdrm, 2 bath,

irri

#<= 50 chars ends here# gation, horse barn. $122,000.

509-697-6519<endad>

So it ends in the middle of the word irrigation and I need it to consume
the whole word.


Here's one idea:

str.sub(/(<begad:[^>]+>.{1,50}.*?\b)/, "\\1<\/ftditm>")
