    <p>I have a web service which receives XML files and does unmarshalling to convert the XML file to an object. The problem is that my web service can receive different XML structures and has to do the correct unmarshalling.</p> <p>So I receibe this kind of XML files:</p> <pre><code>&lt;root&gt; &lt;user&gt; &lt;id&gt;1234&lt;/id&gt; &lt;/user&gt; &lt;XMLelements&gt; ... &lt;/XMLelements&gt; &lt;/root&gt; </code></pre> <p>Notice that <code>XMLelements</code> is an example tag name, every XML file could have differents names.</p> <p>So, I think, my web service workflow should be something like:</p> <ol> <li>It receives XML file.</li> <li>It checks user id. <ul> <li>If user id == 1234 <ul> <li>UserA userA = unmarshalling(XMLFile)</li> </ul></li> <li>Else if user id == 5678 <ul> <li>UserB userB = unmarshalling(XMLFile)</li> </ul></li> <li>Else <ul> <li>UserC userC = unmarshalling(XMLFile)</li> </ul></li> </ul></li> </ol> <p>So I receive different XML structures and for each one I have to do a different unmarshalling to get objects of different classes.</p> <p>How can I perform this approach? I'm using Spring for marshalling (Metro).</p> <p><strong>Edit:</strong> This question didn't receive any answer, maybe I'm not clear. I'll try to explain it better:</p> <p>I have a web service which is listening a url where receives XML files. Actually, in the same url path my web service receives two different XML schemas. How can I know how to do unmarshalling correctly? I mean, unmarshalling should return correct object when different XML schemas are passed.</p>

    1. COWhich part of the XML structure is common to both XML schemas is there an envelope portion?)? What part of the message signals which schema the message corresponds to (is there a body portion?)?

    2. COI'm looking for something like your blog post, but the two different XML schemas have the same root element name, and also some element name.

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.
