     97When the XML source is too large to fit in the memory of xsltproc, I (Pierre Lindenbaum ) use  a custom tool named '''xslstream''' that calls a new XSLT transformation for every chunks of data. For example say you want to convert the XML files of DBSNP ( [ftp://ftp.ncbi.nih.gov/snp/organisms/human_9606/XML/]  e.g. ds_ch1.xml.gz is 1099375 KB ) with dbsnp2rdf.xsl ( http://code.google.com/p/lindenb/source/browse/trunk/src/xsl/dbsnp2rdf.xsl ). Download '''xsltstream''' from http://code.google.com/p/lindenb/downloads/list 
     98And then invoke: 
     99{{{ 
     100java -jar xsltstream.jar -x dbsnp2rdf.xsl   -q "Rs" 'ftp://ftp.ncbi.nih.gov/snp/organisms/human_9606/XML/ds_ch1.xml.gz' |\ 
     101   grep -v "rdf:RDF" |\ 
     102   grep -v "<?xml

    96175Rutger Vos is using a stylesheet that uses XSL2.0 features, which libxslt (on which xsltproc is based) doesn't like. He therefore uses [http://saxon.sourceforge.net/ saxon] to transform NeXML into RDF.
