regex for all characters on yahoo pipes
原标题:

I have an apparently simple regex query for pipes - I need to truncate each item from it s (<img>) tag onwards. I thought a loop with string regex of <img[.]* replaced by blank field would have taken care of it but to no avail.

Obviously I m missing something basic here - can someone point it out?

The item as it stands goes along something like this:

sample text title 
<a rel="nofollow" target="_blank" href="http://example.com"><img border="0" src="http://example.com/image.png" alt="Yes" width="20" height="23"/></a> 
<a.... (a bunch of irrelevant hyperlinks I don t need)...

Essentially I only want the title text and hyperlink that s why I m chopping the rest off

Going one better because all I m really doing here is making the item string more manageable by cutting it down before further manipulation - anyone know if it s possible to extract a href from a certain link in the page (in this case the 1st one) using Regex in Yahoo Pipes? I ve seen the regex answer to this SO q but I m not sure how to use it to map a url to an item attribute in a Pipes module?

You need to remove the line returns with a RegEx Pipe and replace the pattern [ ] with null text on the content or description field to make it a single line of text, then you can use the .* wildcard which will run to the end of the line.
