In visual studio 2005 I am trying to replace all instances of
<img alt="????" src="?????">
with
<img alt="????" src="??????" />

I cannot figure out the appropriate regular expression to use to only find the image tags.

When i use \<img (.)*~(\\)\> it matches
<img alt="??????" src="???????"></td>

Can anyone tell me the right regular expression to use?

Hi dave4dl;

Try this Regex pattern (<img\s*alt\s*=\s*".*?"\s*src\s*=\s*".*?"\s*)(>)
And this replacement string "$1 /$2"

Sorry, i should have been more clear.  I am using regular expressions in the visual studio IDE "Find/Replace" window.

In the visual studio IDE i need to do this find/replace on my code.

Fernando, the regular expression example you posted is not syntax for VS IDE regular expressions.

Yes dave4dl; it makes a big difference Regex in the IDE and the Regex class. So now that I got it straight try this IDE Regex pattern:

        {\<img *alt *= *".@" *src *= *".@" *}{\>}

And this replace4ment string

        \1 /\2

Thank you Fernando.  That looks like it would do some of the substitutions i want to do.

One more thing that I didnt state explicitly is that I would like to do this replacement (adding the "/" before the end of the img tag) on all img tags no matter what attributes are defined in them.

So
<img src=blah.gif> should become <img src=blah.gif />
and
<img alt="blah" border=10 src=hmm.jpg> should become <img alt="blah" border=10 src=hmm.jpg />

basically anything between an instance of "<img " and the very next ">" should be found (no matter what is between those two) except for the case where there is already a slash before the greater than sign "/>"
hence my example of
\<img (.)*~(\\)\>

basically the (.)* was taking too many and i wanted it to stop at the first ">"

\<img [^\>]*~(\\)\>
works ok but it finds cases where the slash-to-add is already present

OK then use this pattern:

        {\<img *[^/]+ *}{\>}

Replacement string:

        \1 /\2
