| <h1 class="topictitle1">Updating XML files with changes made to DTDs and schemas</h1> |
| <div><p>If you make changes to a DTD file or XML schema associated with |
| an XML file (that is currently open), click <b> <span class="uicontrol">XML > Reload Dependencies</span> |
| </b>to |
| update the XML file with these changes.</p><div class="skipspace"><p>The changes will be reflected in the guided editing mechanisms |
| available in the editor, such as content assist.</p> |
| <p>For example, you have |
| a DTD file called "Contact.dtd" and an XML file called "Contact.xml" associated |
| with it. Contact.dtd contains a root element called <span class="uicontrol">Contact</span> that |
| can contain any of the following children elements: <span class="uicontrol">Name</span>, |
| <span class="uicontrol">PostalAddress</span>, <span class="uicontrol">Email</span>. If you |
| remove the child element <span class="uicontrol">Email</span> from the DTD, you will |
| no longer be able to add an <span class="uicontrol">Email</span> child element to |
| your root element Contact in your Contact.xml file. This change, however, |
| will not come into effect until you save your changes in the DTD and click <b> <span class="uicontrol">XML |
| > Reload Dependencies</span></b> in the XML editor. Until you click it, you |
| will still be able to add <span class="uicontrol">Email</span> elements to Contact.xml.</p> |
| <p>This |
| feature is very handy when you are making updates to both DTDs and XML schemas |
| and XML files that are associated with DTDs and XML schemas.</p> |
