indeed. but the you could set up a processor-chain infront of it. I think about something like this:

svgpage.svgxml:
--------------------8<--------------------
<html>
<head>
        <title>My XHTML+SVG</title>
</head>
<body>
        <svg id="image1"><!-- SVG CONTENT --></svg>
</body>
</html>
--------------------8<--------------------

html.xsl
--------------------8<--------------------
<!-- more XSL -->
<xsl:template match="svg">
<!-- replace svg through image -->
  <img>
    <xsl:attribute name="src">
        svgpage.svgxml.png?image_id=<xsl:value-of select="@id" />
    </xsl:attribute>
  </img>
</xsl:template>
<!-- more XSL -->
--------------------8<--------------------

svg.xsl
--------------------8<--------------------
<!-- more XSL -->
<!-- read the cgi-param -->
<xsl:param name="image_id" />

<xsl:template match="/">
        <!-- poor performance but could be optimized -->
        <xsl:copy-of select="//[EMAIL PROTECTED]/*" />
</xsl:template>

<!-- more XSL -->
--------------------8<--------------------

http.conf:
--------------------8<--------------------
<Files ~ *.svgxml>
AxAddStyleMap text/xsl Apache::AxKit::Language::LibXSLT
AxAddProcessor text/xsl /html.xsl
</Files>
<Files ~ *.svgxml.png>
AxAddPlugin Apache::AxKit::Plugin::QueryStringCache
AxAddStyleMap text/xsl Apache::AxKit::Language::LibXSLT
AxAddStyleMap application/svg2anyformat Apache::AxKit::Language::Svg2AnyFormat
## extract the svg from the html
AxAddProcessor text/xsl /svg.xsl
## serialize to png
AxAddProcessor application/svg2anyformat NULL
</Files>
--------------------8<--------------------


Did I get you?

This is only one approach you can e.g. also use a custom provider.

I see that. That only works if your document is entirely SVG though, no?

Hi,

well there are there already exists a Axkit-Transformer for this:
http://search.cpan.org/~tomson/Apache-AxKit-Language-Svg2AnyFormat-0.06/

It uses the Image::LibRSVG-lib which is also owned by me. Svg2AnyFormat also support Image::Magick to transform svg although I think librsvg supports more of the svg-standard than Image::Magick. If you have any problems with the mentionned libs feel free to contact me.
