Hi, all. I'm trying to replace <object ...><embed... /></objectwith

Could anybody help me? Thanks in advance.

I tried to do it myself, but all I did is to replaced

<object width="425" height="355"></
param><param name="wmode" value="transpar ent"></param><embed src="URL"
type="applicati on/x-shockwave-flash" wmode="transpar ent" width="425"
height="355"></embed></object>

with

<object width="425" height="355"></
param><param name="wmode" value="transpar ent"></param><img src="URL"
type="applicati on/x-shockwave-flash" wmode="transpar ent" width="425"

1. My tests indicate that a Flash movie is not played by an `img' element,
so replacing the object-embed element combination would be futile, even
though the `embed' element is proprietary (and therefore not Valid).

2. Using client-side scripting to correct markup is the wrong approach
as it does not need to be available.

3. If necessary, you should rewrite the editor instead.

4. FWIW, in Eclipse I would have used the following parameters:

Search for:
(?s)<object\s+. *?<embed\s+.*?( src=".+?")[^>]*?\s+(width=.+? >)</embed></object>

Replace with:
<img $1 $2 alt="">

(Don't forget the `alt' attribute, give it a descriptive value if
possible/applicable!)

BTW, QuickREx again came in handy in finding that out:
<http://www.bastian-bergerhoff.com/eclipse/features/web/QuickREx/toc.html>

5. With the exception of `(?s)', which can be worked around with
`(?:.|[\r\n])' instead of `.', this should also work with
String.prototyp e.replace() in JavaScript 1.5+ (Mozilla/5.0),
JScript 5.5+ (IE 5.5+), ECMAScript Ed. 3+.

6. Replacing content this way might require using `innerHTML', a
proprietary property that should be avoided in favor of DOM 2 scripting.

I tried your regex:

var flash = '<object width="425" height="355"></param><param
name="wmode" value="transpar ent"></param><embed src="http://
www.youtube.com/v/yVjzd320gew&hl= en" type="applicati on/x-shockwave-
flash" wmode="transpar ent" width="425" height="355"></embed></
object>';

flash = flash.replace(' (?s)<object\s+. *?<embed\s+.*?( src=".+?")[^>]*?\s
+(width=.+?>)</embed></object>', '<img $1 $2 alt=""');

It returns the same object...

I tried to use QuickREx (application, that U noticed) and indeed, it
show matches correct. But in javascript it doesn't replace my text at
all.

It returns a primitive string value, not an object. It returns the same
string it is being applied to because you have not passed a RegExp object
but a string as argument, and you have not read my posting thoroughly
enough. If you had quoted properly, you would have been forced to re-read
before replying and had probably not made this silly mistake.

Thanks, Thomas. I found my mistake. But there is the next trouble.
What if I have more than one <object>'s. It returns only one image. I
need to construct regexp the way, that it will replace only one
node(tag). E.g. <object>...<emb ed src="title".../></
object>...<obje ct>...<embed ... width="455".../></object>
