 <h1 class="topictitle1">Editing namespace information</h1>


 <div><p>Your namespace information is used to provide various information
 about the XML file, such as the XML schema and namespace it is associated
 with. If desired, you can change the schema and namespace your XML file is
 associated with or add a new association. Modifying any associations can impact
 what content is allowed in the XML file.</p>

 <div class="section"><p>The following instructions were written for the Resource perspective,
 but they will also work in many other perspectives.</p>
 <p>To edit your schema
 information, complete the following steps:</p>
 </div>

 <ol>
 <li class="stepexpand"><span>In the Design view of the XML editor, right-click your root element
 and click <span class="uicontrol">Edit Namespaces</span>.</span></li>

 <li class="stepexpand"><span>Your XML file can be associated with more than one namespace or
 schema.</span> Select the entry you want to edit and click <span class="uicontrol">Edit</span>.
 </li>

 <li class="stepexpand"><span>The value in the <span class="uicontrol">Namespace Name</span> field is
 a namespace the XML file is associated with.</span> Your XML file should
 be associated with the same namespace(s) its XML schema is associated with.
 For more information about namespaces, refer to the related reference. For
 more information, see <a href="../../org.eclipse.wst.xsdeditor.doc.user/topics/rnmspc.html">XML namespaces</a>.</li>

 <li class="stepexpand"><span>All qualified elements and attributes in the XML file associated
 with the namespace will be prefixed with the <span class="uicontrol">Prefix</span> value.</span>
 </li>

 <li class="stepexpand"><span>The <span class="uicontrol">Location Hint</span> field contains the location
 of the XML schema the XML file is associated with.</span> An XML Catalog
 Key or a namespace name can be specified in this field. Click <span class="uicontrol">Browse</span> to
 view all XML schemas in the workbench and XML Catalog.</li>

 <li class="stepexpand"><span>Click <span class="uicontrol">OK</span>, then click <span class="uicontrol">OK</span> again.</span>
 </li>

 </ol>

 <div class="section"><p>If you want to create a new association, click <span class="uicontrol">Add</span> instead
 of <span class="uicontrol">Edit</span>. You can then either select the <span class="uicontrol">Specify
 From Registered Namespace</span> radio button and select the namespace
 declarations you want to add or select the <span class="uicontrol">Specify New Namespace</span> radio
 button and fill in the fields as necessary.</p>
 </div>

 <div class="section">If you do not have namespace information in your XML file, you can
 right-click your root element in the Design view and click <span class="uicontrol">Edit
 Namespaces</span> to add it. If you do not have a root element, you must
 create one before you can add the namespace information.</div>
