Books.com/Books List should be validated using the schema file.
XML documents are validated by the Create method of the Xml Reader class. Schema namespace contains extension methods that make it easy to validate an XML tree against an XSD file when using LINQ to XML.
To validate an XML document, construct an Xml Reader Settings object that contains an XML schema definition language (XSD) schema with which to validate the XML document. For more information on validating XML documents with LINQ to XML, see How to: Validate Using XSD.
I need to check that it is wellformed no illegal characters and it has all the tags defined in the XSD i.e no tag missing. After that is done I need to parse the xml file to get the data and store it in database. 1) Using Xml Reader Setttings with Xml Document and Xml Reader with Validate method will that help me acheive what I need? 2) What is the best way to parse an xml file to get specific tags? Add(args) End If End Sub Public Function Get Errors() As String If _errors. Load(xml File Path) Dim schemas As New Xml Schema Set() schemas.
I am new to so any sample code help will be appreciated. Public Class Xml Validation Error Builder Private _errors As New List(Of Validation Event Args)() Public Sub Validation Event Handler(By Val sender As Object, By Val args As Validation Event Args) If args. Count 0 Then Dim builder As New String Builder() builder. Add(Nothing, xsd File Path) Dim error Builder As New Xml Validation Error Builder() doc.
You can use the Xml Validating Reader to validate XML documents against XML Schema definition language (XSD) schemas from multiple schemas.
The Xml Validating Reader constructor takes a stream of an XML fragment, an Xml Node Type, and Xml Parser Context.CODE [XSDInference Examples#6](../Code Snippet/VS_Snippets_Data/XSDInference Examples#6)]In the code example that follows, the schema above is added to the Xml Schema Set Schemas property of the Xml Reader Settings object.The Xml Reader Settings object is passed as a parameter to the Create method of the Xml Reader object, which validates the XML document above. Append Line(" error(s) were found while validating the XML document against the XSD:") For Each i As Validation Event Args In _errors builder. Get Errors() If errors Text Is Not Nothing Then Throw New Exception(errors Text) End If Return doc End Function Public Sub Load Xml(xml File Path As String, xsd File Path As String) Dim settings As New Xml Reader Settings() settings. Validation Event Handler) Dim reader As Xml Reader = Xml Reader. Validation Event Handler)) Dim errors Text As String = error Builder. Validation Event Handler, New Validation Event Handler(Address Of error Builder.The result is a previously un-typed XML sub-tree in the Xml Document replaced with a typed sub-tree.
