LOOKING FOR REGEX TO SPOT MISSING ALT TAGS

Hi there

I'm looking for a VBSCRIPT regex to look into a web page source code and return IMG tags but only those which either have the ALT tag missing - the regex would ideally return the name of the image but simply returning the whole string or nothing would be fine.

Hi Peter
can you give some info?

What are you trying to achive?
Is this script supposed to be embeded in a web page?
Why VBSCRIPT?

It's part of a content management system - when someone edits a page - I look through the source and set a flag for pasted WORD content - which they have to remove .... and for tables that are too large. So I also want to be able to flag up a page that contains one or more images - but wherein the ALT tag is missing from the image. I don't really need to know how many times this occurs - just that it occurs.

VBscript (server side ASP) - because that's what the system is written in - though I would assume the regular expressions are similar in most languages. I know how to actually write the code - it's just the expression I'm unclear on.

Regards

Peter.

Just to be sure, can you post here a minimal example of page containing bad IMG and good IMG example

Good example - bearing in mind that there is no guarantee that double quotes are used - might be single....

<img src="fred.gif" alt="this is a picture of fred">

bad example

<img src="fred.gif">

There may be other attributes such as size etc....
