VS-D-4 DAV Special URI's

DAV Special URI's

WebDAV parameters

The WebDAV server has the following special URL parameters:

• XPATH - the XPATH query to perform against the existing XML document
• set_tag - the root XML element (default is 'document')
• result_tag - the elements tag

Preparation

This example uses the SQL/XML documents generated by VS-D-3.

Example with result_tag

From within a browser do an XPATH query for a subset of attributes. Use the following URL:

http://host:port/DAV/vs_d_3/URLMultiTable.xml?XPATH=/root/Customers/@CustomerID&result_tag=id

Or click this relative link.

Expected result with result_tag

For browsers such as Opera and Netscape, view the source of the result page to see the XML. For browsers capable of rendering the XML, such as Internet Explorer 5+, the XML result will be shown.

This excerpt from the expected output shows the xml document containing the CustomerID only:

   <?xml version="1.0" encoding="ISO-8859-1"?>
   <document>
   <id>
   ALFKI</id>
   <id>
   ANATR</id>
   <id>
   ANTON</id>
   <id>
   AROUT</id>
   <id>
   BERGS</id>
   <id>
   BLAUS</id>
   <id>
   BLONP</id>
   <id>
   BOLID</id>
   <id>
   BONAP</id>
   ...
   </document>

Example with set_tag

Similar to previous example, but replacing result_tag with the set_tag parameter. Enter this URL into a browser:

http://host:port/DAV/vs_d_3/URLMultiTable.xml?XPATH=/root/Customers[@CustomerID+like+'A*']/@CustomerID&set_tag=id

Or click this relative link.

Note: the XPATH queries can only be performed against the persistent storage.

Expected result with set_tag

 <?xml version="1.0" encoding="ISO-8859-1"?>
 <id>
 ALFKIANATRANTONAROUT</id>

Example with set_tag and result_tag

Similar to previous example, but adding result_tag parameter. Enter this URL into a browser:

http://host:port/DAV/vs_d_3/URLMultiTable.xml?XPATH=/root/Customers[@CustomerID+like+'A*']/@CustomerID&set_tag=id&result_tag=p

Or click this relative link.

Note: the XPATH queries can only be performed against the persistent storage.

Expected result with set_tag and result_tag

 <?xml version="1.0" encoding="ISO-8859-1"?>
 <id>
<p>
ALFKI</p>
<p>
ANATR</p>
<p>
ANTON</p>
<p>
AROUT</p>
</id>
