Thanks a lot, it works fine now, fetching subelements properly.The only issue left is that the XPath syntax passed in the data- config.xml does not seem to work properly. As an example, processing the following entity :<root> <contenido id="10097" idioma="cat"> <antetitulo></antetitulo> <titulo> This is my title </titulo> <resumen> This is my summary </resumen> <texto> This is the body of my text </texto> </contenido> </root>and trying to fill a solr field with the 'id' attribute of the 'contenido' tag with the following config :<field column="m_guid" xpath="/root/contenido/@id" /> does not seem to work properly. Thanks a lot for your time already !

I went for the DataImportHandler approach, which seemed to perfectly suit this need. Due to the large amount of XML documents to be indexed ( ~60MB ), i thought i would hardly be possible to feed solr with the concatenation of all these docs at once. Hence this small php script i wrote, serving on HTTP the list of these documents, under the following form ( available from a local URL replicatedin data-config.xml ) : <?xml version="1.0" encoding="UTF-8"?> <root> <entries> <entry> <realm>old_search_content</realm><source>http://localhost/psc/trunk/ezfiles/extension/psc/doc/xml/ 10098.xml</source></entry> <entry> <realm>old_search_content</realm><source>http://localhost/psc/trunk/ezfiles/extension/psc/doc/xml/ 10099.xml</source></entry> <entry> <realm>old_search_content</realm><source>http://localhost/psc/trunk/ezfiles/extension/psc/doc/xml/ all_in_one.xml</source></entry> </entries> </root>The idea would be to have one single data-config.xml configuration file for the DataImportHandler, which would read the listing presented above, and request every single subitem and index it. Every subitem has the followingstructure : <?xml version="1.0" encoding="ISO-8859-1" ?> <root> <contenido id="10099" idioma="cat"> <antetitulo><![CDATA[This is an introduction text]]></antetitulo> <titulo><![CDATA[This is a title]]></titulo> <resumen><![CDATA[ This a a summary ]]></resumen><texto><![CDATA[This is the body of my article<br><br>]]></texto> <autor><![CDATA[John Doe]]></autor> <fecha><![CDATA[31/10/2001]]></fecha> <fuente><![CDATA[]]></fuente> <webexterna><![CDATA[]]></webexterna> <recursos></recursos> <ambitos></ambitos> </contenido> </root> After struggling for a ( long ) while with different configuration scenarios, here is a data-config.xml i ended up with : <dataConfig> <dataSource type="HttpDataSource"/> <document> <entity name="oldsearchcontentlist" pk="m_guid"url="http://localhost/psc/trunk/ezfiles/list_old_content.php? limit=10&urlsonly=1"processor="XPathEntityProcessor" forEach="/root/entries/entry"> <field column="elementurl" xpath="/root/entries/entry/source/" /> <entity name="oldsearchcontent" pk="m_guid"url="$ {oldsearchcontentlist.elementurl}"processor="XPathEntityProcessor" forEach="/root/contenido" transformer="TemplateTransformer"> <field column="m_guid" xpath="/root/contenido/titulo" /> </entity> </entity> </document> </dataConfig> As a note, i had to check out Solr's trunk, and patched it with the following : https://issues.apache.org/jira/browse/SOLR-469 (https://issues.apache.org/jira/secure/attachment/12380679/ SOLR-469.patch ),and recompiled. Running the following command :http://localhost:8983/solr/dataimport?command=full- import&verbose=on&debug=ontells me that no Document was created at all, and does not throw any error....here is the full output : <response> <lst name="responseHeader"> <int name="status">0</int> <int name="QTime">39</int> </lst> <lst name="initArgs"> <lst name="defaults"> <str name="config">data-config.xml</str> <lst name="datasource"> <str name="type">HttpDataSource</str> </lst> </lst> </lst> <str name="command">full-import</str> <str name="mode">debug</str> <null name="documents"/> <lst name="verbose-output"> <lst name="entity:oldsearchcontentlist"> <lst name="document#1"> <str name="query">http://localhost/psc/trunk/ezfiles/list_old_content.php? limit=10&urlsonly=1</str> <str name="time-taken">0:0:0.23</str> </lst> </lst> </lst> <str name="status">idle</str><str name="importResponse">Configuration Re-loaded sucessfully</str><lst name="statusMessages"> <str name="Total Requests made to DataSource">1</str> <str name="Total Rows Fetched">0</str> <str name="Total Documents Skipped">0</str><str name="Full Dump Started">2008-06-10 14:38:56</ str><str name="">Indexing completed.
