xml-nil

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 object having a myIntElementName property with a value of null, rather than a JAXBElement object with a

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" /> 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 is true , then the property it is controlling is serialized. Otherwise, if it is false , the other property

I'm trying to select from XML that has a null as one of the attributes. Instead of returning a null, it returns a 0. What am I doing wrong? See code below to replicate: declare @a xml select @a = '<TestSet xmlns:xsi="http://www.w3.org/2001/XMLSchema-instace"> <Element> <Property1>1</Property1> <Property2>1</Property2> </Element> <Element> <Property1 xsi:nil="true" /> <Property2>2</Property2> </Element> <Element> <Property1>3</Property1> <Property2>3</Property2> </Element> </TestSet>' select ParamValues.TaskChainerTask.query('Property1').value('.','int') as Property1, ParamValues

do you know if there's a difference between these tags on XML/XSD? <a_element /> and <a_element xsi:nil="true"/> e.g: <SpreadCurve> <Index>3M</Index> <IndexNumber>4587</IndexNumber> <BusinessArea xsi:nil="true" /> </SpreadCurve> and <SpreadCurve> <Index>3M</Index> <IndexNumber>4587</IndexNumber> <BusinessArea /> </SpreadCurve> Are these equivalent ? If I have a XSD element: <xsd:element name="BusinessArea" type="xsd:string"/> this means that it is by default xsi:nil="false". And this means it will not accept a null value for this element. My doubt is, will it accept this one? <BusinessArea />

I have a java property annotated with @XmlElement(required=false, nillable=true) . When the object is marshalled to xml, it is always outputted with the xsi:nil="true" attribute. Is there a jaxbcontext/marshaller option to direct the marshaller not to write the element, rather than write it with xsi:nil ? I've looked for answers to this and also had a look at the code, afaics, it will always write xsi:nil if nillable = true . Am I missing something? If the property is annotated with @XmlElement(required=false, nillable=true) and the value is null it will be written out with xsi:nil="true" . If
