Clarification on XML schema ?????Dear all,
What is the real puprose on using an XML schema (XSD) ??? This is still a bit unclear for me, is it just in case we would like to tranmit data to an other applciation and rebuild a dataset based on that schema or is there other reason ? thnaks for your reply regards serge Validation. You can make sure you get and make documents in right format.

outside world and I just need to read them , do I need that schema any way ? I understand that schema is usufull when you are writting data in order that they match with the format you are expected, but when you simply wnat to read them I do not think that schema is a must .. What is your opinion ? regards Show quoteHide quote "Eliyahu Goldin" wrote: > Validation.

You make your choice depending on your
preferences, the same as with all other validations. You may choose to be sure that what you get is already validated and then you don't have to care much about exceptions in the code. Or, alternatively, you may choose not to validate your input and take care of exceptions in the code. Of cause you can choose also partial validation.

How then you validate that the
entry is corresponding to what is expected ? When you do such thing I guess the purpose is to write directly in the xml file or do you usually pass through a dataset object first ?
