问题 I am receiving XML from a server whose schema specifies nearly every element as: <xs:element name="myStringElementName" type="xs:string" nillable="true" minOccurs="0"/> <xs:element name="myIntElementName" type="xs:int" nillable="true" minOccurs="0"/> I'm trying to find a clean way to convert every element that I receive that is marked as xsi:nil="true" to a null when it is unmarshalled into a JAXB object. So something like this: <myIntElementName xsi:nil="true" /> Should result in my JAXB

问题 I have a c# class that has 20+ string properties. I set about a fourth of those to an actual value.

问题 when I serialize a c# object with a nullable DateTime in it, is there a way to leave the null value out of the xml file instead of having <EndDate d2p1:nil="true" xmlns:d2p1="http://www.w3.org/2001/XMLSchema-instance" /> 回答1: You can use the Specified extended property to leave out null values (or any other value, for that matter). Basically, create another property with the same name as the serialized property with the word Specified added to the end as a boolean. If the Specified property

问题 I have seen null elements represented in several ways: The element is present with xsi:nil="true" : <book> <title>Beowulf</title> <author xsi:nil="true"/> </book> The element is present, but represented as an empty element (which I believe is wrong since 'empty' and null are semantically different): <book> <title>Beowulf</title> <author/> </book> <!-- or: --> <book> <title>Beowulf</title> <author></author> </book> The element is not present at all in the returned markup : <book> <title

问题 In .NET, you can serialize a nullable element using XmlElement( IsNullable = true ), which results in this: <SomeElement xsi:nil="true" />. However, I need to be able to add xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance after any field that is being nulled out. Example: <SomeElement xsi:nil="true" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/> Is this possible? 回答1: I figured it out. Here is the answer: [XmlElement(IsNullable = true, Namespace = "http://www.w3.org/2001

问题 I have following xml which contains several xml tags with xsi:nil="true". These are tags that are basically null. I am not able to use/find any sxlt transformer to remove these tags from the xml and obtain the rest of the xml. <?xml version="1.0" encoding="utf-8"?> <p849:retrieveAllValues xmlns:p849="http://package.de.bc.a"> <retrieveAllValues> <messages xsi:nil="true" /> <existingValues> <Values> <value1> 10.00</value1> <value2>123456</value2> <value3>1234</value3> <value4 xsi:nil="true" />
