But also see the messages about Oracle's building of XML from the data set returned from an SQL query...

 

From: Abhishek Srivastava

 

I tried the Oracle's SQL - XML utility and it does what i want.  Except a few things.

 

I generated the following XML file as a result to a query to my oracle database.

 

<ROWSET>
 <ROW num="1">
  <SPNAME>Huntington services Company             </SPNAME>
  <CUSTPERMID>123456789123456     </CUSTPERMID>
  <CUSTLOGINID>jamesb              </CUSTLOGINID>
  <FIRSTNAME>james </FIRSTNAME>
  <LASTNAME>Bond </LASTNAME>
 </ROW>
 </ROW>
</ROWSET>

 

The ROWSET and the ROW tags were introduced by the builder itself. I would like the document to look like :

 

<CUSTID>

<SPNAME>My Own Business  Services Company  </SPNAME>
  <CUSTPERMID>123456789123456     </CUSTPERMID>
  <CUSTLOGINID>jamesb              </CUSTLOGINID>
  <FIRSTNAME>james               </FIRSTNAME>
  <LASTNAME>Bond                </LASTNAME>
 </CUSTID>

This is very important because this xml file will be sent to the client who will "validate" it. Since ROWSET and ROW are not a part of standard message format we use... an exception will be thrown.

Is there any way to customize the output from the builder so that it conforms to a predefined DTD ?

Abhishek,

 

Most of the XML Parser implementations provides mechanism to generate well formed XML documents from the DOM Tree. I have used sun's XML parser, it provides APIs to generate well-formed XML from your Document Node.

 

Hope it helps.

Hi All,

 

I have the following requirement. A client wants to query a database. It sends out an SQL Query to the Database server. At the server side, instead of returning a recordset, it returns an XML File.

 

The client on receiving the XML file, parsers it for "Validity" (to be sure that all elements it had asked for are there).

 

Problem is that at the server side, How to build the xml document.

Presently, I am doing something like this

 

String("<Name>") + rs.getField("auName") + String("</Name>")

 

However, this is a very inelegant approach as the code is full of such string concatenations.

 

Is there a more elegant solution to this ?  All the material on XML talks about parsing and reading XML. What about writing them ? Are there DOM / SAX Api extensions available that would

create "VALID" XML documents without clutter in the code ?

 

Any help would be greatly appreciated.

 

Thanks & Best Regards,

Abhishek.
