Source: saveDOMsmart.cpp

This C/C++ source code performs the following steps:

1. Creates an XML DOM object (pXMLDom) and sets it to synchronous mode.
2. Loads an XML string to pXMLDom.
3. Calls the loadXML method on pXMLDom, specifying the XML data as the following string:

   <r>\n<t>top</t>\n<b>bottom</b>\n</r>

4. Displays the resulting XML DOM in the console window.
5. Calls the save method on pXMLDom to serialize the DOM content to a file (myData.xml).

To add the saveDOMsmart source code to the project

1. Create a new C++ source file. For detailed instructions on how to do this, see Set Up My Visual C++ Project. Name the new file saveDOMsmart.cpp.
2. Copy the C/C++ source code above and paste it into the source file you just created.

Next, build and run the saveDOMsmart project. The result should be the output shown in the following topic.
