Lance Norskog commented on SOLR-1354:
-------------------------------------
Ow! Heck. The multi-valued param feature is a good point.
One problem that came up is localization - fetching the local dateformat and
formatting dates in the RSS feed according to the caller's locale. This would
require pulling the incoming HTTP headers and feeding them to the XSL as
parameters.
Are there other request handlers that could use parameters? For example, the
Velocity handler? How can it localize Velocity applications without the HTTP
local header?

> Key: SOLR-1354
> URL: https://issues.apache.org/jira/browse/SOLR-1354
> Project: Solr
> Issue Type: New Feature
> Components: search
> Environment: Any JDK from 1.5 onward. Any OS. Uses standard XSLTC
> 'compiled'-only version of Apache Xalan distributed with the JRE.
> Reporter: Lance Norskog
> Priority: Minor
> Attachments: rss2.patch
>
>
> It is not possible to create a standard web application with the Solr
> distribution without coding in XSL, Ruby, HTML/Javascript etc.
> This patch is an experiment that allows you to configure an RSS 2.0 feed
> through HTTP parameters. To do this, it supplies:
> 1) a change to XSLTWriter.java to pass an HTTP parameter named 'tr.name'
> through as an XSL parameter called 'name'. The XSL script must then declare
> 'name' as a global parameter.
> 2) example/solr/conf/xslt/rss2.xsl - a mostly complete implementation of RSS
> 2.0.
> 3) a sample <requestHandler> in example/solr/conf/solrconfig.xml which
> configures solr/rss2 as an RSS feed for the sample electronics store in
> example/solr. This <requestHandler> supplies all parameters for the RSS feed.
