[ http://issues.apache.org/jira/browse/SOLR-49?page=comments#action_12435553 ] Yonik Seeley commented on SOLR-49: ----------------------------------
Thanks Bertrand, I've not used servlet filters before. What do people think the tradeoffs are of using a different url "/select/html" vs a different response writer "wt=html&wt.xslt=..." ? Anyone else have opinions on if this should be committed? > PATCH: XSLTServletFilter > ------------------------ > > Key: SOLR-49 > URL: http://issues.apache.org/jira/browse/SOLR-49 > Project: Solr > Issue Type: New Feature > Components: search > Environment: Tested on macosx 10.4.7, JDK 1.5.0_06 > Reporter: Bertrand Delacretaz > Priority: Minor > Attachments: xslt-filter-files.tar.gz > > > Patch that implements server-side XSLT transforms of query results. > The filter is activated by using select/html instead of select/ to run > queries, and optionally adding a transform parameter to specify the XSLT > transform to use, for example: > http://localhost:8983/solr/select/html?q=usage&transform=my.xsl > In which case my.xsl should be found in solr/conf/xslt/ with the example > configuration. The default transform (solr/conf/xslt/query-to-html.xsl) > outputs a simplistic HTML format. > Performance is suboptimal, as the filter reparses the XML output generated by > Solr. Modifying the XMLWriter to output to a ContentHandler would be more > efficient, but I didn't have time to go that far. > The TransformerProvider trivially caches the last Transformer used, could be > improved using an LRU cache of several transformers, I haven't checked if > Solr's infrastructure contains such an animal already. > The patch is all new files, except for adding this in web.xml before the > first <servlet>: > <filter> > <filter-name>xslt</filter-name> > <filter-class>org.apache.solr.xslt.XSLTServletFilter</filter-class> > </filter> > <!-- apply the XSLT filter when select/html is used to make queries --> > <filter-mapping> > <filter-name>xslt</filter-name> > <url-pattern>/select/html/*</url-pattern> > </filter-mapping> > I've left the client-side XSLT stuff (stylesheet parameter) as is for the > moment. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
