    Finding expression between two words

    Hi,

    I want to find a string as part of a long expression. I am using regexp match but with no success,

    Actually I am trying to find what is in between <embed> and </embed>
    can any one help me with this one. The code attached below


    Code is attached below:

    Code:
    <html>

<head>

<title></title>
<script language="javascript" type="text/javascript">
    function validateFlashMoview() 
    {
  
    var flashString='<object width="425" height="355"><param name="movie" value="http://www.youtube.com/v/ItXDJy1JHvE&hl=en"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/ItXDJy1JHvE&hl=en" type="application/x-shockwave-flash" wmode="transparent" width="425" height="355"></embed></object>';
        var flashArray=flashString.match(/(embed*)+(*embed)/gi);
     
       for (i=0;i<flashArray.length;i++) 
       {
         alert(flashArray[i]);
       }
     //document.getElementById('flashMovie').innerHTML="'"+flashString+"'";
    }

</script>
</head>

<body>


<div id="flashMovie"></div>
<input name="test" id="test" type="button" value="test" onclick="validateFlashMoview()">
<br>

</body>

</html>

      If you're trying to get the attributes of the embed tag in an array, just split on whitespace using the split() method. Alternatively, add the elements to the page, get the embed tag and just access them directly using:
      [code=javascript]var embed = document.getEle mentsByTagName( "embed")[0];
      var src = embed.src; // ... and so on[/code]

          Thanks Acoder,

          The issue is that I want to find out what is between the two embed open and close tag if exist using the regexp, I want to do it in one shot.


          How this line should be written?
          Code:
          var flashArray=flashString.match(/(embed*)+(*embed)/gi);

              Didn't you try innerHTML?
              [code=javascript]var txt = document.getEle mentsByTagName( 'embed')[0].innerHTML;[/code]

                  That wouldn't work unless the elements have been added to the page.

                  @raknin, any reason why you must do this via a string and not have it added to the page first?

                      Something like:
                      Code:
                      var content = str.match( /<embed.*>(.*)<\/embed>/i )[1] || "";
