Everyone please keep in mind that DOAP is not an XML format, it's an
RDF format which is often serialized with RDF/XML, and there are many
ways to specify the same RDF graph in RDF/XML.

Assuming appropriate namespace declarations, all these are equivalent:

<doap:Project rdf:about="#threadweaver">
  <doap:name>ThreadWeaver</doap:name>
  <doap:shortdesc>ThreadWeaver is a helper for multithreaded
programming</doap:shortdesc>
</doap:Project>


<rdf:Description rdf:about="#threadweaver">
  <rdf:type>http://usefulinc.com/ns/doap#Project</rdf:type>
  <doap:name>ThreadWeaver</doap:name>
  <doap:shortdesc>ThreadWeaver is a helper for multithreaded
programming</doap:shortdesc>
</rdf:Description>


<rdf:Description rdf:about="#threadweaver">
  <rdf:type>http://usefulinc.com/ns/doap#Project</rdf:type>
</rdf:Description>
<rdf:Description rdf:about="#threadweaver">
  <doap:name>ThreadWeaver</doap:name>
</rdf:Description>
<rdf:Description rdf:about="#threadweaver">
  <doap:shortdesc>ThreadWeaver is a helper for multithreaded
programming</doap:shortdesc>
</rdf:Description>

And this is just a simple example with literal strings, I didn't even
add references to other resources (as it would be needed for
doap:maintainer). To parse it you *really* need an RDF library, not
just an XML parser. Do we really want this complexity?
