• XML validation error when using multiple schema files/namespaces

  - by user129609

  Hi, I've been reading a ton about xml and learning a lot but I am stuck on one error. I have a schema defined in multiple files and I can't get it to work. Here is an example ================================== libraryBooks.xsd <?xml version="1.0" encoding="utf-8"?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="urn:MyNamespace" targetNamespace="urn:MyNamespace" elementFormDefault="qualified" > <xsd:element name="libraryBooks" type="libraryBooksType"/> <xsd:complexType name="libraryBooksType"> <xsd:sequence> <xsd:any minOccurs="0"/> </xsd:sequence> <xsd:attribute name="name" type="xsd:string"/> </xsd:complexType> </xsd:schema> ================================== book.xsd <?xml version="1.0" encoding="utf-8"?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="urn:MyNamespace2" targetNamespace="urn:MyNamespace2" elementFormDefault="qualified" > <xsd:element name="book" type="booksType"/> <xsd:complexType name="bookType"> <xsd:attribute name="title" type="xsd:string"/> </xsd:complexType> </xsd:schema> ================================== myXml.xml <?xml version="1.0" encoding="utf-8" ?> <libraryBooks xmlns="urn:MyNamespace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:MyNamespace file:///C:/libraryBooks.xsd" name="CentralLibrary"> <mn2:book xmlns:mn2="file:///C:/book.xsd" title="How to make xml work the way I want"> </mn2:book> </libraryBooks> So the error I get would be "The 'file:///C:/book.xsd:book' element is not found". Any ideas? I'm almost certain it is something simple

• NHibernate & Cancelling Changes to Entities

  - by user129609

  Hi, This seems like it would be a common issue to be but I don't know the best way to solve it. I want to be able to send an Entity to a view, have changes be made to the entity in the view, but then cancel (remove) those changes if the user cancels out of the view. What is the proper way to do this. Here are two options I have but I think there should be others that are better 1) Take an entity, create a clone, send the clone to the view...if changes are accepted, update the original entity with the clone's values 2) Send the entity to the view, if the user cancels, remove the entity from NHibernate's cache and reload it from the database For (2), the issue for me would be that the old entity could still be referenced throughout my project after it has been removed from the cache.
