Try It!
- Copy the XML data (books.xml), and paste it into a text file. Save the file as books.xml.
- Copy the XSD listing (books.xsd), and paste it into a text file. Save the file as books.xsd, in the same directory where you saved books.xml.
- Copy the JScript listing above, and paste it into a text file. Save the file as errorParams.js, in the same directory where you saved books.xml and books.xsd.
- Double click the errorParams.js file from Windows Explorer to launch the application. Alternatively, you can type "errorParams.js" from a command prompt.
Note 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.
- Verify that your output is the same as that listed in Output for the errorParams Example.
