I'm trying to write a basic program that grabs a page from a website
then
"scrapes" through the HTML to get the data I want. Currently, I am
using
initWithContentsOfURL: to get the page into a NSString. So I am
getting the
full page no problem.
What I want to do is extract all the text from in between a pair or
tags
(<td>...</td> for example). I know I could use a rangeOfString: call
to get
the first one, but then I have to create a new string with the
remaining
data and call rangeOfString: again to get the next and on and on until
the
whole string is parsed. I hope there is a better way to do this.
CFXMLParser would seem to be the thing you want. See the Core
Foundation XML services documentation. As long as your html is
well-formed, it should be relatively easy.
