Just as you have an xslt response writer to convert Solr xml response to make it compatible with any application, on the input side do you have an xslt module that will parse xml documents to solr format before posting them to solr indexer. I have gone through dataimporthandler, but it works in data 'pull' mode i.e. solr pulls data from the given location. I would still want to work with applications 'posting' documents to solr indexer as and when they want.
