xslt playing an mp3 via xml

Question

I have an xml feed and I need to play an mp3 from the feed. I have set up the player

    <div class="musicplayer">
<div id="musicplayercontainer060251712481gbakw0201569t"></div>
<script type="text/javascript">
    var flashvars = {file:"music/betty.mp3",as:"0"};
    var params = {wmode: "transparent"};
    var attributes = {};
    swfobject.embedSWF("images/player.swf", "musicplayercontainer060251712481gbakw0201569t", "23", "23", "9.0.0","expressInstall.swf", flashvars, params, attributes);
</script></div>

and it works fine if i pass the mp3 directly but I have to pass it from the xml so I replaced the betty.mp3 with <xsl:value-of select="clipUrl"/> but it won't play. is there a syntax i need to use?

e.g.

var flashvars = {file:"<xsl:value-of select="clipUrl"/>",as:"0"};

thanks

Answer 1

it is just when I replace betty.mp3 so like

<div class="musicplayer">
<div id="musicplayercontainer060251712481gbakw0201569t"></div>
<script type="text/javascript">
    var flashvars = {file:"<xsl:value-of select="clipUrl"/>",as:"0"};
    var params = {wmode: "transparent"};
    var attributes = {};
    swfobject.embedSWF("images/player.swf", "musicplayercontainer060251712481gbakw0201569t", "23", "23", "9.0.0","expressInstall.swf", flashvars, params, attributes);
</script></div>

Personally if you don't have any XHTML based expando hangups you could do this instead:-

<div class="musicplayer">
  <div id="musicplayercontainer060251712481gbakw0201569t"
      audioSrc="{clipUrl}"
  ></div>
  <script type="text/javascript">
    var elem = document.getElementById("musicplayercontainer060251712481gbakw0201569t");
    var flashvars = {file:elem.getAttribute("audioSrc"), as:"0"};
    var params = {wmode: "transparent"};
    var attributes = {};
    swfobject.embedSWF("images/player.swf", "musicplayercontainer060251712481gbakw0201569t", "23", "23", "9.0.0","expressInstall.swf", flashvars, params, attributes);
  </script>
</div>

This way you don't embedded xsl instructions in your script code where output encoding may be messing things up.
