xml-validation

How can one validate an XML file using an XSD in Java? We don't know the schema in advance. I would like to be able to get the schemaLocation , download the XSD, cache it and then perform the actual validation. The problem is, that with javax.xml.parsers.DocumentBuilder / DocumentBuilderFactory classes I can't seem to be able to get a hold of the schemaLocation in advance. What's the trick for this? Which classes should I look into? Perhaps there's a more suitable API I can use? The whole problem is that we need to validate dynamically, without (necessarily) having the XSDs locally. How could

My C#/.NET application reads XML files that are manually edited by the users. The allowed elements and tags are described in the application's documentation. I'm using LINQ to extract data from the XML file. Before extracting data from the XML file, I'd like to validate it to see if it has the expected structure. If not, it would be nice to have information about what is wrong so that I can give some feeback to the user. What's the simplest way to do this in C#? CoderHawk You can validate xml files against XSD. First you have to create Xml Schema Definition file. See example use XML Schema

Here is my first attempt at validating XML with XSD. The XML file to be validated: <?xml version="1.0" encoding="utf-8" ?> <config xmlns="Schemas" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="config.xsd"> <levelVariant> <filePath>SampleVariant</filePath> </levelVariant> <levelVariant> <filePath>LegendaryMode</filePath> </levelVariant> <levelVariant> <filePath>AmazingMode</filePath> </levelVariant> </config> The XSD, located in "Schemas/config.xsd" relative to the XML file to be validated: <?xml version="1.0" encoding="utf-8" ?> <xs:schema xmlns:xs="http:

I have xml files that I read in at runtime, is is possible to validate the xml against an xsd file at runtime? using c# Try this: public void ValidateXmlDocument( XmlReader documentToValidate, string schemaPath) { XmlSchema schema; using (var schemaReader = XmlReader.Create(schemaPath)) { schema = XmlSchema.Read(schemaReader, ValidationEventHandler); } var schemas = new XmlSchemaSet(); schemas.Add(schema); var settings = new XmlReaderSettings(); settings.ValidationType = ValidationType.Schema; settings.Schemas = schemas; settings.ValidationFlags = XmlSchemaValidationFlags

Maybe it's me, but it appears that if you have an XSD <?xml version="1.0" encoding="utf-8"?> <xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="User"> <xs:complexType> <xs:sequence> <xs:element name="GivenName" /> <xs:element name="SurName" /> </xs:sequence> <xs:attribute name="ID" type="xs:unsignedByte" use="required" /> </xs:complexType> </xs:element> </xs:schema> that defines the schema for this document <?xml version="1.0" encoding="utf-8" ?> <User ID="1"> <GivenName></GivenName> <SurName></SurName> <

I have an XSD to validate an XML file. The structure is as follows: <root> <child> <size>2</size> <childElement>Element 1</childElement> <childElement>Element 2</childElement> </child> </root> The number of childElement s is dependent on the size provided i.e. if size was set as 3, not more than 3 childElement s can be added. I have tried using xs:alternative but it does not seem to work: <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="root"> <xs:complexType> <xs:sequence> <xs:element name="child" minOccurs="1" maxOccurs="unbounded"> <xs:complexType> <xs:sequence> <xs
