pulling and using an uri from an rss encode tag

coflo

I am relatively new to XSL transforms so I apologize if my language or verbage is incorrect.

I am trying to invoke a JS function of a flash player which requires a URI. In order to do this I would like to take the RSS feed, the snippet below, and grab the uri from the <enclosure> tag. You will see that there is a &uri=channels/39174/186941 inside of the url="" i would like to grab this piece and insert it into my XSL <a href= as currently defined by $item_enclosure.

Here is my XML:

<item>

<title>New Show: Mobile Show 434</title>

<link>http://www.kyte.tv/ch/39174-flocam/186941-mobile-show-434</link>

<media:content url="http://www.kyte.tv/flash.swf?appKey=MarbachViewerEmbedded&amp;uri=channels/39174/186941&amp;layoutMode=default" fileSize="30" type="application/x-shockwave-flash" height="425" width="425" duration="1"/>

<enclosure url="http://www.kyte.tv/flash.swf?appKey=MarbachViewerEmbedded&amp;uri=channels/39174/186941&amp;layoutMode=default" length="30" type="application/x-shockwave-flash"/>

</item>

As you can see in my XSL im able to pull the url and insert it but i have no idea how to extract the uri=channels/39174/186941

Here is my attempt XSL:

Expand|Select|Wrap|Line Numbers

 
<xsl:template match="item">

<xsl:variable name="item_link" select="link"/>

<xsl:variable name="item_enclosure" select="enclosure/@url"/>

<xsl:variable name="item_title" select="description"/>

<xsl:variable name="item_media" select="media"/>

<div class="subHead" style="width:300px;">

<a href="javascript:void(kyteplayer.setURI('{$item_enclosure}'))"><xsl:value-of select="title" disable-output-escaping="yes"/></a></div>

<div style="width:300px;">

<xsl:value-of select="description" disable-output-escaping="yes"/><br/></div>
 
(<xsl:value-of select="pubDate"/>)<br/> <hr/>

Getting the url:
substring-after(//enclosure/@url/, 'uri=')
This gets everything after uri=
Now the problem is, is there another argument afterwards? If so, we can take everything before the &; if not we simply take the whole substring.

Expand|Select|Wrap|Line Numbers

 
<xsl:variable name="afterURI" select="substring-after(//enclosure/@url/, 'uri=')"/>

<xsl:variable name="URIVal">

  <xsl:choose> 

      <xsl:when test="contains($afterURI, '&amp;amp;')">

         <xsl:value-of select="substring-before($afterURI, '&amp;amp;')"/>

      </xsl:when>

      <xsl:otherwise>

        <xsl:value-of select="$afterURI"/>

      </xsl:otherwise>

   </xsl:choose>

</xsl:variable>

Then when you want to output this,

Expand|Select|Wrap|Line Numbers

 
<a href="javascript:void(kyteplayer.setURI('{$URIVal}'))"><xsl:value-of select="title" disable-output-escaping="yes"/></a>

I seem to be getting an error: SAXParseException: Unterminated entity reference

it is always pointing to the line that starts with

Expand|Select|Wrap|Line Numbers

 <xsl:variable name="afterURI" select="substring-after(//enclosure/@url/, '&uri=')"/>

Ahh!! I got it, took a bit of playing around but thank you so much for your help - here is my final result working!

Expand|Select|Wrap|Line Numbers

 
<xsl:template match="item">
 
  <xsl:variable name="item_link" select="link"/>

  <xsl:variable name="item_enclosure" select="enclosure/@url"/>

  <xsl:variable name="item_title" select="description"/>

  <xsl:variable name="item_media" select="media"/> 
 
<xsl:variable name="afterURI">

<xsl:value-of select = "substring-after($item_enclosure, '&amp;uri=')" />

</xsl:variable>
 
       <xsl:variable name="URIVal">

        <xsl:choose>

            <xsl:when test="contains($afterURI, '&amp;')">

               <xsl:value-of select="substring-before($afterURI, '&amp;')"/>

            </xsl:when>

            <xsl:otherwise>

              <xsl:value-of select="$afterURI"/>

            </xsl:otherwise>

         </xsl:choose>

      </xsl:variable>
 
  <div class="subHead" style="width:500px;">

    <a href="javascript:void(kyteplayer.setURI('{$URIVal}'))"><xsl:value-of select="title" disable-output-escaping="yes"/></a></div>

    <div style="width:500px;">

 <xsl:value-of select="description" disable-output-escaping="yes"/><br/></div>
 
 (<xsl:value-of select="pubDate"/>)<br/> <hr/>

 </xsl:template>

edit: humm the & isnt showing up correctly it should be & a m p

yeah, the code tags seem to automatically unescape & as &, sorry forgot about that quirk.
