Hi,
Christophe, you are right, searchRequestElement contains the query as
defined by DASL (see
http://greenbytes.de/tech/webdav/draft-reschke-webdav-search-latest.html for
current draft). When designing SEARCH, we discussed having a non-DOM data
object for describing the query. A possible way would be to use the
abstraction as used by WVCM. But then SEARCH would be limited to the
basicsearch syntax (DASL is open to define other syntaxes). Everything is
well defined in DASL, so we did not see an overwhelming advantage designing
a different datastructure.
See following example for creating a simple query:
-------------------------------------------------------------
import org.jdom.Element;
import org.jdom.Namespace;
import org.jdom.output.XMLOutputter;
public class CreateSearch
{
public static void main(String[] args) throws Exception
{
Namespace davNamespace = Namespace.getNamespace ("d", "DAV:");
Element searchRequest = new Element ("searchRequest", davNamespace);
Element basicSearch = new Element ("basicSearch", davNamespace);
searchRequest.addContent (basicSearch);
Element select = new Element ("select", davNamespace);
basicSearch.addContent(select);
Element prop = new Element ("prop", davNamespace);
select.addContent(prop);
prop.addContent(new Element ("getcontentlength", davNamespace));
Element from = new Element ("from", davNamespace);
basicSearch.addContent(from);
Element scope = new Element ("scope", davNamespace);
from.addContent(scope);
Element href = new Element ("href", davNamespace);
href.addContent("myFolder");
scope.addContent(href);
Element where = new Element ("where", davNamespace);
basicSearch.addContent(where);
Element gt = new Element ("gt", davNamespace);
where.addContent (gt);
Element p2 = new Element ("prop", davNamespace);
gt.addContent(p2);
p2.addContent(new Element ("getcontentlength", davNamespace));
Element literal = new Element ("literal", davNamespace);
literal.addContent("10000");
p2.addContent(literal);
XMLOutputter out = new XMLOutputter (" ", true);
out.output (searchRequest, System.out);
}
}
-------------------------------------------------------------------------
This sample creates a searchRequest Element which displays as:
<d:searchRequest xmlns:d="DAV:">
<d:basicSearch>
<d:select>
<d:prop>
<d:getcontentlength />
</d:prop>
</d:select>
<d:from>
<d:scope>
<d:href>myFolder</d:href>
</d:scope>
</d:from>
<d:where>
<d:gt>
<d:prop>
<d:getcontentlength />
<d:literal>10000</d:literal>
</d:prop>
</d:gt>
</d:where>
</d:basicSearch>
</d:searchRequest>
which means nothing else than: Give me the contentlengths of all resources
within or below myFolder, that are larger than 10000 bytes.
Hope this helps,
Martin

Subject: Re: SlideAPI: SearchHelper
If I remember correctly, searchRequestElement is a xml jdom element
which contains the complete search criteria. the grammareUri is the
namespace uri defined in this jdom element.
There is a sample in :
jakarta-slide\src\webdav\server\org\apache\slide\webdav\method\SearchMethod.
java.
So, we are at least 2 (you and me :-) ) who are using Slide without the
webdav layer.
Now, I have a question for the committers : is it not interesting to
have less coupling between the webdav layer and this search helper
class. My point of view is it is better to have a real "data object"
instead of a jdom element.
I have no idea on how to build this jdom element if I'm not using the
webdav layer. Or at least, maybe someone can point to a document which
describe how to build those parameters.
