      Re: regex question

      Why not simply "<img[^>]>"?

          thanks for replying. However I found this worked better for me

          myregex = New Regex("<img .*?(>|(/>|(</img>))",
          RegexOptions.Ig noreCase Or
          RegexOptions.Ex plicitCapture)
          It does not gobble up other tags fooling the <img .....on the same line.
          it also supposed to take care of xml also

          Credit is due to Dave Sexton for helping arriving at the above expression

              There is never ever an ending tag for the img tag, and even if there
              were, your pattern doesn't handle that.

                  Re: regex question

                  So far I have not seem ending tag for <img ..at least for html.

                  although I think I have sees some comments of XML <img tags and <object tags
                  both have ending tags of sorts

                  I did made mistake in thr regex for the ending tag by leaving out one right
                  paranthesis

                  myregex = New Regex("<img .*?(>|(/>)|(</img>))",

                      Yes, but XML is a completely different thing. There the tag name "img"
                      has no special meaning at all.

                      It still doesn't handle the ending tag, if there ever was one. As the
                      starting tag ends with ">" that will be caught instead of the ending tag.
