Function with example. Simple enough.

URL for Craigslist - go to the section you want to read and look at the URL.

_CLSectionToArray("City", "Section", "Pages - default is 1")

So http://phoenix.craigslist.org/wvl/vgm/ would be

_CLSectionToArray("phoenix", "wvl/vgm")

If you wanted the first few pages

_CLSectionToArray("phoenix", "wvl/vgm", 3)

And it'll return a 2 Dimensional array with the page ID in the first field and the description in the second.

Edit: I only designed and tested it in sections I needed it for, so no promises in other classified sections heh

Edit 2: Doesn't work on city's with sub sections, i'll mess around with that. You just need to search each sub section.

StringRegExp() errors for me.

I see that using the example I gave (never tested it just chose a city at random lol).

Using Albany, VGM it works fine. Under Phoenix/boston/other large cities it actually sub categorizes.

I'll mess around with that heh

Been designing these functions to work as declared. The subsections you just need to declare in the section.

http://phoenix.craigslist.org/wvl/vgm/2186282764.html

Would be

_CLSectionToArray("phoenix", "wvl/vgm", 1)

Not as dynamic but it works
