  1. POXML Schemas (XSD> - Can a non-empty element have a type and an attribute?
    text
    copied!<p>i'm relatively new to XML Schemas and i've encountered a problem. I know that for an element to have an attribute assocaited with it, it must be a complex type. However I can only figure out how to associate an attribute with an empty element (See Example 1)...is it possible to assocaite an attribute with a non-empty elemnet and have a type declared for that element (See Example 2)? I'm using Visual Studio 2008 to write the schemas...when i declare the element as a complex type it tells me that I have to remove the type declaration from the element - see below.</p> <p>Example 1:</p> <pre><code>&lt;phone units = "grams" /&gt; </code></pre> <p>Example 2:</p> <pre><code>&lt;phone units = "grams"&gt;92&lt;/phone&gt; </code></pre> <p>Phone.XML</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;phone xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="XSD.xsd"&gt; &lt;make&gt;Nokia&lt;/make&gt; &lt;model&gt;N700&lt;/model&gt; &lt;code&gt;532/4329&lt;/code&gt; &lt;weight units ="grams"&gt;92&lt;/weight&gt; &lt;price&gt;49.99&lt;/price&gt; &lt;/phone&gt; </code></pre> <p>XSD.xsd</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"&gt; &lt;xs:attribute name ="units" type ="xs:string" /&gt; &lt;xs:element name ="phone"&gt; &lt;xs:complexType&gt; &lt;xs:sequence&gt; &lt;xs:element name ="make" type="xs:string" /&gt; &lt;xs:element name ="model" type="xs:string" /&gt; &lt;xs:element name ="code" type="xs:string" /&gt; &lt;xs:element name ="weight" type="xs:string"&gt; &lt;xs:complexType&gt; &lt;xs:attribute name="units" type="xs:string" /&gt; &lt;/xs:complexType&gt; &lt;/xs:element&gt; &lt;xs:element name ="price" type="xs:double" /&gt; &lt;/xs:sequence&gt; &lt;/xs:complexType&gt; &lt;/xs:element&gt; &lt;/xs:schema&gt; </code></pre> <p>I have yet to find an example on the net demonstrating this. Is it possible or do I have to sacrifice the type associated with the weigh element in order to insert the attribute?</p> <p>Any help would be much appreciated....Thanks....</p>
