Subject: [xsl] handling media, xsl:variable problem From: Nathan Shaw <n8_shaw@xxxxxxxxx> Date: Wed, 1 May 2002 12:18:58 -0700 (PDT) |
(I would appreciate a direct reply as I am a digester and am working with a tight deadline! Please remember to cc the list as well though!) I am trying to setup a template to handle MEDIA elements, which can be images, video or audio. I am trying to use a variable to store the actual img or embed tag to use later on in placement of the media file, but for some reason, the variable is coming out empty. If I add some basic text in the variable, it is captured and output as expected. So, it is just the img or embed tags that are being ignored/omitted for some reason... I am using Saxon and outputting as XHTML. Here is an exmaple media element and the media template. Suggestions and/or comments welcome. TIA --Nate <!-- media element --> <Media type="image" id="issrail" file="http://www.nasa.gov/images/031902_issrail.jpg" align="left" width="110" height="83" border="0" alt="Space Railroad"> <Caption align="bottom">Space Railroad</Caption> <Link type="internal" url="http://spacerailroad.nasa.gov/" /> </Media> <!-- media template --> <xsl:template match="Media"> <xsl:variable name="media1"> <xsl:choose> <xsl:when test="@type='image'"> <img id="{@id}" src="{@file}" width="{@width}" height="{@height}" align="{@align}" border="{@border}" alt="{@alt}" /> </xsl:when> <xsl:when test="@type='audio'"> <embed id="{@id}" src="{@file}" height="{@height}" width="{@width}" autostart="false" loop="false" /> </xsl:when> <xsl:when test="@type='video'"> <embed id="{@id}" src="{@file}" height="{@height}" width="{@width}" autostart="false" loop="false" /> </xsl:when> </xsl:choose> </xsl:variable> <xsl:variable name="media2"> <xsl:choose> <xsl:when test="Link and Link!=''"> <a> <xsl:attribute name="href"> <xsl:value-of select="@url" /> </xsl:attribute> <xsl:if test="@type='external'"> <xsl:attribute name="target"> <xsl:value-of select="'_blank'" /> </xsl:attribute> </xsl:if> <xsl:value-of select="$media1" /> </a> </xsl:when> <xsl:otherwise> <xsl:value-of select="$media1" /> </xsl:otherwise> </xsl:choose> </xsl:variable> <xsl:choose> <xsl:when test="Caption and Caption!=''"> <table cellspacing="0" cellpadding="3" border="0"> <xsl:choose> <xsl:when test="Caption/@align='top'"> <tr><td valign="top" class="piccaption"><xsl:value-of select="Caption" /></td></tr> <tr><td><xsl:value-of select="$media2" /></td></tr> </xsl:when> <xsl:when test="Caption/@align='left'"> <tr><td valign="top" class="piccaption"><xsl:value-of select="Caption" /></td> <td><xsl:value-of select="$media2" /></td></tr> </xsl:when> <xsl:when test="Caption/@align='right'"> <tr><td><xsl:value-of select="$media2" /></td> <td valign="top" class="piccaption"><xsl:value-of select="Caption" /></td></tr> </xsl:when> <xsl:when test="Caption/@align='bottom'"> <tr><td><xsl:value-of select="$media2" /></td></tr> <tr><td valign="top" class="piccaption"><xsl:value-of select="Caption" /></td></tr> </xsl:when> </xsl:choose> </table> </xsl:when> <xsl:otherwise> <xsl:value-of select="$media2" /> </xsl:otherwise> </xsl:choose> <xsl:if test="@width > 600"> <br clear="all" /> </xsl:if> </xsl:template> __________________________________________________ Do You Yahoo!?
