Dear Wiki user, You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.
The following page has been changed by NoblePaul: http://wiki.apache.org/solr/DataImportHandler The comment on the change is: simplified httpdatasource documentation ------------------------------------------------------------------------------ It moves ahead and encounters `/RDF/item` and processes the rows one by one . It gets the values for all the fields except for the 3 fields in the header. But as they were marked as common fields, the processor puts those fields into the record just before creating the document. - What about this ''transformer=!DateFormatTransformer'' attribute in the entity? This is an inbuilt utility transformer helps the user parse his date strings in custom format to 'Date' objects . Note the field `<field column="date" xpath="/RDF/item/date" dateTimeFormat="yyyy-MM-dd'T'hh:mm:ss" />` . The transformer only applies to a field which has the attribute 'dateTimeFormat' and it uses the syntax of [ http://java.sun.com/j2se/1.4.2/docs/api/java/text/SimpleDateFormat.html java's !SimpleDateFormat]. + What about this ''transformer=!DateFormatTransformer'' attribute in the entity?

You can use this feature for indexing from REST API's such as rss/atom feeds, XML data feeds , other SOLR servers or even well formed xhtml documents . Our XPath support has its limitations but we have tried to make sure that common use-cases are covered and since it's based on a streaming parser, it is extremely fast and consumes constant amount of memory even for large XMLs. Easy, isn't it? And you didn't need to write one line of code! Enjoy :)
