DASL Search for files with a particular file extension

["Martin, Tammy (US SSA)" <ta...@baesystems.com>]

Hi all,

I am trying to write a DASL Search query to search for files on the
server with a particular file extension. I am able to search for content
like the example at http://wiki.apache.org/jakarta-slide/DASLSearch .

However, when I try to modify this query to find a file extension the
query does not work.  Here is one of the versions of the query:

String path = webdavStorageAreaPath;
String fileExtQuery =
                "<D:searchrequest xmlns:D =\"DAV:\">" +
                "<D:basicsearch>" +
                "<D:select>" +
                "<D:prop>" +
                "<D:getcontentlength/>" +
                "</D:prop>" +
                "</D:select>" +
                "<D:from>" +
                "<D:scope>" +
                "<D:href>" + path + "</D:href>" +
                "<D:depth>infinity</D:depth>" +
                "</D:scope>" +
                "</D:from>" +
                "<D:where>" +
                 "<D:eq>" + "<D:prop>" + "<D:displayname/>" +
"</D:prop>" +
               "<D:literal>" + "*.txt" + "</D:literal>" + "</D:eq>" +
                "</D:where>" +
                "</D:basicsearch>" +
                "</D:searchrequest>";

Does anyone know how to set up a query for all files with a certain
extension?  Also where is the documentation for what properties are
available and how or can wildcards be used?  Any help that you could
provide would be greatly appreciated.

Thanks,
Tammy

The DASL spec defines a like operator:
http://greenbytes.de/tech/webdav/draft-reschke-webdav-search-07.html#rfc.section.5.15

which however is not supported by Slide. You may want to use Slide's 
proprietary:
<D:where>
   <SLIDE:propcontains xmlns:SLIDE="http://jakarta.apache.org/slide/">
     <D:prop><D:displayname/></D:prop>
     <D:literal>.txt</D:literal>
   </SLIDE:propcontains>
</D:where>
