preg replace question.

[Blooish]

I need to change spaces to $nbsp; only inside the values of the attributes of some tags. For example <a href="./One script.html"></a> should become <a href="./One&nbsp;script.html"></a>.
I tried to use preg_replace('/="\s\s+"/i','&nbsp;',$string) but it doesnt seem to work.
Any Help is appreciated!

Someone else can probably come up with a better one but this looks like it's working:
#(a href[^\s]+)([\s])#

yeah, but i want to change spaces in all attributes of a tag, not only href.

Why? I mean, what is the intended use here? If that href is really a URL you should consider rawurlencode [php.net]. For everything else, perhaps you should consider htmlentities [php.net].

coopster, you didn't understand my question. I needed to create a script to exctract url from a webpage and its attributes. I found a solution,but sometimes it doesnt exctract url, for example for google <a href=somelink></a> ,coz my script looks for <a href="somelink"></a>.
Anyway thanks for your attention.

First you said you needed to replace certain entities. Now you are saying you want to extract. Indeed, I am not understanding your question ;)

If you are trying to locate links in a web page, have you searched the forums here yet? There are many threads here that demonstrate how to do so with many examples of regular expressions.
