I know there is a boolean OR; it is |. However is there a boolean AND? For instance, how do I match a string that I know has "farrel" somewhere in it and has "august" somewhere in it.

But not x,y or z. I want them as one group. Apparently [^(xyz)] picks either of the letters. I want to say that it should pick the things not having xyz as group together. Is that possible? Thanks How would I select everything that is not “xyz.” But not x,y or z. I want them as one group.

Apparently [^(xyz)] picks either of the letters. I want to say that it should pick the things not having xyz as group together.

Is that possible?

Thanks

I subscribed to the feed using my browser's built in RSS reader. Does that count or do I have to use feedburner? I am trying to use jquery to break Right Ascension / Declination data into their constituents (hours , minutes, and seconds) and (degrees, arc-minutes and arc-seconds), respectively from a string and store them in variables as numbers. E.g. $dec = "-35:48:00" -> $dec_d = -35, $dec_m = 48, $dec_s = 00 I have gotten as far as (-|)+\d+ to get the expression to extract the first part but now I am stuck. I cannot figure out how to use jquery to break apart the string and store the information in the variables I need. Maybe this will inspire a topic for a future tutorial. I appreciate any help you can provide. I have searched long and hard online but have not found something that makes sense. Hi Jeff,

Thanks a bunch for the tutorials.

I have gotten as far as
(-|)+\d+
to get the expression to extract the first part but now I am stuck. I cannot figure out how to use jquery to break apart the string and store the information in the variables I need.

Really cool! One question: whats the name of the espresso theme you use? I like it. Where can I get this theme? In the Coffee House I didn't find it... :-( Thanks for this great screencast!

Wed, 06 May 2009 11:14:22 +0000 http://blog.themeforest.net/?p=1755#comment-9872 This was a very interesting tutorial. Thanks Jeff! A question for Jeff or to anyone else that is experienced with scraping: would this be a viable technique to use on a personal site if you wanted to, say, scrape your latest tweet on Twitter? For example, I could easily see this being used in a real-world example to scrape data from Twitter's supplied XML feeds for your account. I suspect this may not be optimal though. I recall reading something in the comments here on Themeforest that its best to use a cache of some sort so that your servers don't have to keep 'scraping' Twitter every time the page loads. This is a new topic for me, so don't quote me on that. Just trying to put the pieces together. If scraping isn't optimal for this use, can someone post up a link to a technique that would be a better choice? This was a very interesting tutorial. Thanks Jeff!

Here’s the regex I used.

/]*href=["\'](?!javascript)([^#"\']+)["\']/i

it works like Phil’s, but strips out javascript links (w/a negative lookahead) and strips out links to other anchors on the same page.

I have only been studying jQuery and javascript for six months,thus I found this tutorial looking for instruction on how to append the last list item to the beginning of an unordered list in jQuery. As I tried to use $('li:last')appendto('ul:first') (i left out the period quotations on purpose) it only appended the list item to the first list item. Anyway, thank you again.
