XML and WSDL Validation

If you are looking to  perform either of these functions then go no further than downloading the free Java IDE tools, Eclipse or Netbeans. Both of these have adequate functionality for validating XMLs and WSDLs. The latest review on the comparison of these two tools is that they both compare almost on par. Therefore up to you on which one you download. I chose NetBeans so, download from here NetBeans or if you prefer Eclipse

To validate from Netbeans:
1. From main menu select File->Open and select the file to validate
2. Select the validate XML icon
3. Check the Output:XML Check window for errors
