    <p>I want to know if there is anyway for removing not required elements from generated xml using jaxb.I have my xsd element definition as follows.</p> <pre><code> &lt;xsd:element name="Title" maxOccurs="1" minOccurs="0"&gt; &lt;xsd:annotation&gt; &lt;xsd:documentation&gt; A name given to the digital record. &lt;/xsd:documentation&gt; &lt;/xsd:annotation&gt; &lt;xsd:simpleType&gt; &lt;xsd:restriction base="xsd:string"&gt; &lt;xsd:minLength value="1"&gt;&lt;/xsd:minLength&gt; &lt;/xsd:restriction&gt; &lt;/xsd:simpleType&gt; &lt;/xsd:element&gt; </code></pre> <p>As you can see it is not a mandatory element because</p> <blockquote> <p>minOccurs="0"</p> </blockquote> <p>But if it is not empty the length should be 1.</p> <pre><code>&lt;xsd:minLength value="1"&gt;&lt;/xsd:minLength&gt; </code></pre> <p>At the time of marshalling if I left the Title field blank it is throwing the <strong>SAXException</strong> because of min-length restriction. So what I want to do is to remove the whole occurrence of <code>&lt;Title/&gt;</code> from generated XML.Right now i have removed the min-length restriction so it is adding the <code>&lt;Title&gt;</code> element as <strong>EMPTY</strong></p> <pre><code>&lt;Title&gt;&lt;/Title&gt; </code></pre> <p>But I do not want it like this.Any help is appreciated.I am using jaxb 2.0 for Marshalling.</p> <p><strong>UPDATE:</strong></p> <p>Following is my variable definiton : </p> <pre><code> private JAXBContext jaxbContext; private Unmarshaller unmarshaller; private SchemaFactory factory; private Schema schema; private Marshaller marshaller; </code></pre> <p>Marshalling code.</p> <pre><code> jaxbContext = JAXBContext.newInstance(ERecordType.class); marshaller = jaxbContext.createMarshaller(); factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI); schema = factory.newSchema((new File(xsdLocation))); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); ERecordType e = new ERecordType(); e.setCataloging(rc); /** * Validate Against Schema. */ marshaller.setSchema(schema); /** * Marshal will throw an exception if XML not validated against * schema. */ marshaller.marshal(e, System.out); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
