Use the C++ XML Data Source Object

This topic discusses the C++ XML Data Source Object (DSO). DSO was implemented for MSXML 3.0. Later versions of MSXML do not support it.

Windows® Internet Explorer supports C++ Data Source Object (DSO) that can be used to bind XML to HTML, as well as Java XML DSO . The new C++ DSO gives you better performance and the ability to bind directly to an XML data island.

The C++ DSO allows you to create XML-driven Web applications in a completely declarative fashion, although it is still possible to write scripts against the XML document object. With the C++ DSO, both the Microsoft ActiveX® Data Objects (ADO) and XML object models are available to you.

Consider the following XML file.

<universities>
  <university>
    <name>UCSB</name>
    <location>Santa Barbara, CA</location>
  </university>
  <university>
    <name>University of Texas at Arlington</name>
    <location>Arlington, TX</location>
  </university>
  <university>
    <name>USM</name>
    <location>Hattiesburg, MS</location>
  </university>
  <university>
    <name>Baylor</name>
    <location>Waco, TX</location>
  </university>
</universities>


You can bind this XML to a repeating table with the following HTML.

<XML ID=xmlDoc src="universities.xml"></XML>
<TABLE DATASRC="#xmlDoc" BORDER=1> 
  <THEAD><TH>NAME</TH><TH>LOCATION</TH></THEAD>
  <TR>
    <TD><SPAN DATAFLD="name"></SPAN></TD>
    <TD><SPAN DATAFLD="location"></SPAN></TD> 
  </TR>
</TABLE>

There is no need for an <APPLET> or <OBJECT> tag; the XML DSO does all the work for you.
