JScript Code (importNode.js)

 

[This sample code uses features that were implemented only in MSXML 6.0.]

Try It!

  1. Copy the first piece of XML data (doc1.xml), and paste it into a text file. Save the file as doc1.xml.

  2. Copy the second piece of XML data (doc2.xml), and paste it into a text file. Save the file as doc2.xml, in the same directory where you saved doc1.xml.

  3. Copy the JScript listing above, and paste it into a text file. Save the file as importNode.js, in the same directory where you saved doc1.xml and doc2.xml.

  4. Double click the importNode.js file from Windows Explorer to launch the application. Alternatively, you can type "importNode.js" from a command prompt.

    Under operating systems other than Windows 2000 or Windows XP, you might need to install Windows Scripting Host (wscript.exe), if it is not already installed.

  5. Verify that your output is the same as that listed in Output for the importNode Example.
