49 <title>Using Code Completion in XML Files Constrained by an XML Catalog</title>
52 <h2>Using Code Completion in XML Files Constrained by an XML Catalog</h2>
53 <p><small><a href="#seealso">See Also</a></small></p>
54 <p>You can use an XML catalog that is registered in the IDE to constrain an XML instance document.</p>
56 <p><b>To use an XML catalog to constrain a new XML document:</b></p>
58 <li>In the IDE, open the Services window.</li>
59 <li>Expand the <tt>DTD and XML Schema Catalogs</tt> node, then expand the catalog node, right-click the catalog entry node and choose View.<br>
60 The Source Editor opens the catalog entry in read-only mode.</li>
61 <li>Make a note of the <tt>targetNamespace</tt> value (<tt><i>schema-targetNamespace</i></tt>) and the root or top-level element (<tt><i>schema-root-element</i></tt>) in the schema.</li>
62 <li>In the IDE, create a new XML document by doing the following:<br>
64 <li>From the main menu, choose File > New File.<br>
65 The New File wizard opens.</li>
66 <li>Under Categories, select the <tt>XML</tt> node and under File Types, select the <tt>XML Document</tt> node, then click Next.</li>
67 <li>Specify a name and location for the document and click Next.</li>
68 <li>Select the XML Schema-Constrained Document radio button and click Next.</li>
69 <li>In the Schema Options page of the wizard, click Finish without completing any of the fields.<br>
70 The IDE creates the new XML document in the specified location.</li>
72 <li>In the XML document, select the <tt>root</tt> tag,<br>
74 <root xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
75 xsi:noNamespaceSchemaLocation='null'>
79 and replace it with the following:
81 <<i>schema-root-element</i>
82 xmlns:<i>prefix</i>='<i>schema-targetNamespace</i>'
83 xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
84 xsi:schemaLocation='<i>schema-targetNamespace</i> <i>schema-targetNamespace</i>'>
86 </<i>schema-root-element</i>>
89 <li>In the Source Editor tab of the XML document, position the cursor where you want to start adding content and type an opening left angle bracket (<tt><</tt>).<br>
90 The code completion box opens. This box provides a scrolling list of schema elements. The list of elements is based on the XML schema from the XML catalog that constrains the XML instance document.</li>
