The whole dblp dataset is available as one big XML file. You can find the XML dump of dblp in this directory. The directory contains:
dblp.xmlis an XML file which contains all bibliographic records,
dblp.xml.gzis a compressed version of this file (gzip),
dblp.dtdis the document type definition you need to validate the XML file.
The XML file is rebuilt every time a new build of the dblp web pages has been computed. You can always check for the timestamp of the XML file in the directory to learn when a new build is ready.
