RE: [docbook-apps] svg and <object> tag conflict

["Day, Troy L" <tlday at pbsj dot com>]

The small modification was to utilize a new parameter.

 

<xsl:param name="use.object.for.svg" select="'1'"/>

 

Which was used like this:

 

  <xsl:variable name="img">

    <xsl:choose>

          <xsl:when test="@format = 'SVG'">

         

          <!-- Removing object tag for svg files-->

          <xsl:if test="$use.object.for.svg != 0">

                <object data="{$filename}" type="image/svg+xml">

                 <xsl:call-template name="process.image.attributes">

                 <!--xsl:with-param name="alt" select="$alt"/ there's no alt here-->

                 <xsl:with-param name="html.depth" select="$html.depth"/>

                   <xsl:with-param name="html.width" select="$html.width"/>

                   <xsl:with-param name="longdesc" select="$longdesc"/>

                   <xsl:with-param name="scale" select="$scale"/>

                   <xsl:with-param name="scalefit" select="$scalefit"/>

                   <xsl:with-param name="scaled.contentdepth" select="$scaled.contentdepth"/>

                   <xsl:with-param name="scaled.contentwidth" select="$scaled.contentwidth"/>

                   <xsl:with-param name="viewport" select="$viewport"/>

                 </xsl:call-template>

                 <xsl:if test="@align">

                   <xsl:attribute name="align">

                       <xsl:choose>

                         <xsl:when test="@align = 'center'">middle</xsl:when>

                         <xsl:otherwise>

                           <xsl:value-of select="@align"/>

                         </xsl:otherwise>

                       </xsl:choose>

                   </xsl:attribute>

                 </xsl:if>

          </xsl:if>

         

          <xsl:if test="$use.embed.for.svg != 0">

 

            <embed src="{$filename}" type="image/svg+xml">                   

              <xsl:call-template name="process.image.attributes">

                <!--xsl:with-param name="alt" select="$alt"/ there's no alt here -->

                <xsl:with-param name="html.depth" select="$html.depth"/>

                <xsl:with-param name="html.width" select="$html.width"/>

                <xsl:with-param name="longdesc" select="$longdesc"/>

                <xsl:with-param name="scale" select="$scale"/>

                <xsl:with-param name="scalefit" select="$scalefit"/>

                <xsl:with-param name="scaled.contentdepth" select="$scaled.contentdepth"/>

                <xsl:with-param name="scaled.contentwidth" select="$scaled.contentwidth"/>

                <xsl:with-param name="viewport" select="$viewport"/>

              </xsl:call-template>

            </embed>

          </xsl:if>

          <!-- Removing object tag for svg files-->

          <xsl:if test="$use.object.for.svg != 0">

               </object>

          </xsl:if>

      </xsl:when>

     

 

Perhaps this template could be componentized in future releases to make customization more workable.

 

Thanks,

Troy

The template that generates the object element with embed inside (name="process.image" in html/graphics.xsl) is a very large template (over 500 lines).  It has an xsl:choose case for SVG (<xsl:when test="@format = 'SVG'">), and it would not be difficult to remove the <object> element that it generates.  But it means copying that large template to your customization layer and making a small modification. That should work, but it means you will have to check each stylesheet release to see if that big template has changed at all, and repeat the process.

Subject: [docbook-apps] svg and <object> tag conflict

 

 

(How can I create an embed tag for svg graphics without nesting it inside an <object> tag? )

 

Perhaps some clarification of 'why' is in order.  I'm trying to include some complex svg graphics within docbook for html transformation.  Although the svg graphic shows up fine using the Adobe viewer, the svg scripting is not working.  The svg software maker informed me :

 

"... the problem is, that the <embed> tag is inside an <object> tag. The <object> tag makes problems with svg and is not fully supported by all browsers."

 

Client is Using IE 6, so a nested embed tag should work (and does work for simple viewing of the svg), but the svg _javascript_ files are not working. 

 

The curious thing is that if I save the transformed file as an html file then view it from the file system like this:

 

C:\Inetpub\wwwroot\...\xml_translate[1].html

 

The svg and scripting works fine.  It is only when the html markup is viewed from a URL like this:

 

http://localhost/.../xml_translate[1].html

 

does the problem occur.

 

This appears to be an IE/<object> tag problem, so I want to simply use the embed tag not nested within the object tag for svg graphics. 

 

Any ideas about how to customize the xsl would be greatly welcome.

 

Thanks,

Troy
