SUMMARY
=======

This simple example shows how to return values from an XML document using
Microsoft Visual FoxPro.

MORE INFORMATION
================

This example uses the Microsoft XML (MSXML) parser to move data from an XML
document to a FoxPro table. The parser is available at:

  http://msdn.microsoft.com/xml/default.asp

The following code creates the Microsoft MSXML ActiveX object to accesses
information contained in an XML document and displays it:

1. Install the MSXML parser.

2. Create the XML document by copying the sample XML code below to a text file
  and name the file with the extension .

3. Create a FoxPro program file with the following code and run the program:

  PUBLIC oXML  

  oXML=CREATEOBJECT('msxml.domdocument')  && This creates the parser object

  oXML.LOAD(GETFILE('xml'))  && This gets and loads the XML document. 

  *** Select the XML document created from the XML code below.

  *** The following gives the basename / RootElemant of the XML document
  ? oXml.DocumentElement.Basename 

  *** The following gives the number of nodes (or records)           
  ? oXML.documentelement.childnodes.LENGTH  

  *** REMEMBER that the object model is in base zero.
  *** Therefore use the following in looping expressions  
  ? oXML.documentelement.childnodes.LENGTH - 1

  *** The following returns the number of child nodes contained under the first Item
  *** This is useful for looping through a childes elements
  *** FOR ichild = 0 TO oXML.documentelement.childnodes.ITEM(0).childnodes.LENGTH - 1
  ? oXML.documentelement.childnodes.ITEM(0).childnodes.LENGTH - 1

  *** The following returns the nodename of the childnode  
  ? oxml.documentelement.childnodes.item(0).childnodes(0).nodename

  *** The following returns the data contained in the childnode
  ? oXML.documentelement.childnodes.ITEM(0).childnodes(0).TEXT

  *** Returns a string of all the data contained in the second child / record
  ? oXml.documentelement.childnodes.item(1).nodetypedvalue
