You might be interested in Lux (http://luxdb.org), which is designed for
indexing and querying XML using Solr and Lucene. It can run
index-supported XPath/XQuery over your documents, and you can define
arbitrary XPath indexes.

Hi, I'm a newby trying to index PubMed texts obtained as xml with similar
structure to:
http://eutils.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi?db=pubmed&retmode=xml&id=23864173,22073418
The nodes I need to extract, expressed as XPaths would be:
//PubmedArticle/MedlineCitation/PMID
//PubmedArticle/MedlineCitation/DateCreated/Year
//PubmedArticle/MedlineCitation/Article/ArticleTitle
//PubmedArticle/MedlineCitation/Article/Abstract/AbstractText
//PubmedArticle/MedlineCitation/MeshHeadingList/MeshHeading
I think a way to index them in Solr is to create another xml structure similar
to:
<add>
<doc>
<field name="id">PMID</field>
<field name="year_i">Year</field>
<field name="name">ArticleTitle</field>
<field name="abstract_s">AbstractText</field>
<field name="cat">MeshHeading1</field>
<field name="cat">MeshHeading2</field>
</doc>
</add>
Being "PMID" = '23864173' and "ArticleTitle" = 'Cost-effectiveness of
low-molecular-weight heparin compared with aspirin for prophylaxis against venous thromboembolism
after total joint arthroplasty' and so on.
With that structure I would post it to Solr using the following statement over
the documents folder
java -jar post.jar *.xml
I'm wondering if is there a more direct way to perform the same task that does not imply a
'iterate->parsing->restructure->write to disk->post' cycle
Many thanks
Francisco
