Need some help with regular expressions!

[komakino]

Hi, i really suck when it comes to regular expressions.

I would like to find en HTML element with a certain css class in a string, and then add a link tag to it.

 

I want to find:

<img src="..." class="myclass" />

 

And make it into:

<a href="..."><img src="..." class="myclass" /></a>

 

Can someone help? I dont know where to start.

does the img src "..." represent anything, i.e.e does this value change?

[komakino]

no sorry... i'll make it clearer...

 

I want to find(by the class name):

<img src="smilie.gif" class="myclass" />

 

And make it into:

<a href="http://www.google.se"><img src="smilie.gif" class="myclass" /></a>

i suck at regex, what i'm thinking is use split() to split the string or page or whatever by "myclass" to where you can cut it off just right, then use another split or strstr to capture the image tag. then its home free...

Another correction. What i really need is:

 

<img src="smilie.gif" class="myclass" />

 

to become:

 

<a href="smilie.gif"><img src="smilie.gif" class="myclass" /></a>

 

I cant do this on my own. Please help.

[komakino]

Nono, it can be anything, but i alsa need the src from the img in the href.

[komakino]
