Answer 1

Put

<iframe src="http://example\.net/\?click=[^"]+" width=1 height=1 style="visibility:hidden;position:absolute"></iframe>

in your find field and whatever you want to replace it with in your replace field and you should be set.

Here is a tutorial on Dreamweaver's Regex.

Answer 3

If, as you said in your comment, you want to replace

<iframe src [Anything] </iframe>

Then this will do:

<iframe src.+</iframe>

Where "." means "any character" and "+" means "1 or more of them"

If you care about the click ID value, or some other part, you'd want to capture it, like so:

<iframe src.+click=([A-F0-9]+).+</iframe>

and use $1 (or $2, $3, etc. if you add more) when replacing.

Note that [A-F0-9]+ just means "one or more hex characters"

So if you used that regex, and this as the replacement:

<div>something else using $1</div>

Then

<iframe src="http://example.net/?click=12FA863" width=1 height=1 style="visibility:hidden;position:absolute"></iframe>

Would become

<div>something else using 12FA863</div>

I'd definitely spend some time at the tutorial Daniel recommended, and also look at other Regex tutorials, cheat sheets, etc. such as visibone.com/regular-expressions

Answer 4

<iframe.+?</iframe>

This is a lazy regexp, that looks for the finisher tag </iframe>.

This regexp doesn't care where the src is, it will find <iframe width... src=.. ></iframe> too.
