Do you just want to get the src or are you interested in all the attributes?
If just the source then something like this should do it:
#ReReplaceNoCase(Input, "(<img.*?src.*?=.*?"").*?("".*?>)",
"\1#NewSource#\2")#
You'll have to tweak it. I'm not even sure it'll run - but I think it will!
The power of positive thinking!
You'll have to make it more complex to also understand things like single
quotes instead of double quotes.
If you want ALL of the attributes then a nice (but, honestly, slow) way to
do it is to find all of the img tags (a regex like "<img.*?>" should do
that) rip them out of the source and treat each one like an XML doc (using
XMLParse()).
You can then navigate the tag and its attributes like an XML document.
This will only work on well formed code (so you might have to insert an end
slash if its not there.
Hope this helps,
