  • Googling for XML
    by Bob DuCharme
    This article gives examples about how wide is exploration googling for MXL, for specific document types, and googling for RDF. A google search for Xml files may show plenty of XHTM. Google apparently indexes the entire DocBook document. If the researcher are not really interested in RDF or other king of XML, this resources will discourage its use.
