Hello Alfred,
Say have a url 'http://mysite.com/cocoon/test.xml' and I want to add an
option to save the same test.xml file as a zip archive.
I see now that if I have the following sitemap:
<map:match pattern="*.zip">
<map:generate src="nothing.xml" type="file"/>
<map:transform src="zip.xsl">
<map:parameter name="source" value="{1}"/>
</map:transform>
<map:serialize type="zip"/>
</map:match>
<map:match pattern="*">
<map:generate src="{1}.xml"/>
<map:serialize type="xml"/>
</map:match
Where nothing.xml is effectively an empty xml file having only <xml></xml>
tags.
And the zip.xsl is as follows:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns="http://mine";>
<xsl:param name="source"/>
<xsl:template match="/">
<zip:archive xmlns:zip="http://apache.org/cocoon/zip-archive/1.0";>
<zip:entry>
<xsl:attribute name="name"><xsl:value-of
select="$source"/></xsl:attribute>
<xsl:attribute name="src">cocoon:/<xsl:value-of
select="$source"/></xsl:attribute>
</zip:entry>
</zip:archive>
</xsl:template>
</xsl:stylesheet>
I am directing the output of the "*" pipeline into the "*.zip" pipeline.
This almost seems to work, but the browser does not seem to understand that
file is a zip, so maybe I'm still doing something incorrectly, thanks for
your help.
