  1. POIs this XML example possible to write a schema for?
    text
    copied!<p>I have two XML examples that I want to write a schema for:</p> <p>Example 1: </p> <p><code>&lt;attributes&gt;</code><br> <code>&lt;attribute type="test" value="yes"/&gt;</code><br> <code>&lt;/attributes&gt;</code></p> <p>Example 2:</p> <p><code>&lt;attributes&gt;</code><br> <code>&lt;attribute type="test"&gt;</code><br> <code>&lt;value x="100" y="50"&gt;yes&lt;/value&gt;</code><br> <code>&lt;/attribute&gt;</code><br> <code>&lt;/attributes&gt;</code></p> <p>Example 3:</p> <p><code>&lt;attributes&gt;</code><br> <code>&lt;attribute type="test" value="no"&gt;</code><br> <code>&lt;value x="100" y="50"&gt;yes&lt;/value&gt;</code><br> <code>&lt;/attribute&gt;</code><br> <code>&lt;/attributes&gt;</code></p> <p>Is it possible to have a schema that works for these? With 'value' being an attribute in one and an element in the other?</p> <p><strong>Update</strong> Right, I think I understand my problem now.</p> <p>I have this XSD:</p> <pre><code>&lt;xs:complexType name="Attribute"&gt; &lt;xs:sequence &gt; &lt;xs:element name="value" type="Value" minOccurs="0" maxOccurs="unbounded"&gt; &lt;/xs:element&gt; &lt;/xs:sequence&gt; &lt;xs:attribute name="type" type="xs:string" use="required"&gt; &lt;/xs:attribute&gt; &lt;xs:attribute name="value" type="xs:string" &gt; &lt;/xs:attribute&gt; &lt;/xs:complexType&gt; </code></pre> <p>But when I try to use JAXB to generate java classes from the XSD I get an error:</p> <pre><code> [xjc] [ERROR] Property "Value" is already defined. Use &amp;lt;jaxb:property&gt; to resolve this conflict. [xjc] line 275 of file:common.xsd [xjc] [ERROR] The following location is relevant to the above error [xjc] line 286 of file:common/common.xsd [xjc] failure in the XJC task. Use the Ant -verbose switch for more details </code></pre> <p>I guess this is a limitation in JAXB rather than the XSD. It will try to create two methods called getValue() which will fail. </p>
