Following are the steps to using Xml Reader Settings for validating an XML file: The code behaves the same in both the cases.
However, there is a small difference in how the exception message is displayed.
A schema is used to validate the structure and data of an XML file.
If an XML file conforms to its schema, it is considered to be valid.
If you have been using some other method, please do share it here.
I am having some trouble validating XML using the Xml Validating Reader. Read(Validator Reader, Address Of Validation Event Handler) Validation Schema. ] the Read operation is feeding its resulting SOM into the Validation Schema object that you're going to compile and add into a collection later, what is actually happening is, Xml Schema.
:-) I say "throwing it all away" because Read is a Shared Sub.
Being an observant programmer, I'm sure your eyes bugged out when I described what was happening on the second line, so let's go back to that.
So, whereas from looking at the line, Validation Schema.
Please note that this class has been marked obsolete in . Lets assume that the XML file that we wish to validate has details about orders.
Net framework 2.0 which recommends using XMLReader. Each of the Order contains the Order ID, details about the Customer, Discount percent given and the details about Products.
Create() with proper XMLReader Settings for validating the document. Following graphic(click for larger image) shows the XML file that we are using: To validate the XML shown above, we have the schema. Please note that in absence of event mentioned in point (3), an exception will be thrown on the first error encountered in XML file where as in case of having the Validation Event Handler hooked up, all the errors in the XML file can be displayed.
Following code shows the steps mentioned above: Validating XML using Xml Reader Settings follows almost the same path as that for Xml Validating Reader, with a difference that here we will be using Xml Reader Settings to pass in the schema details.It provides you mechanism to provide a XML file, add a schema and validate the XML file supplied against the schema.
