- Shows the use of the OpenLayers XML format class
- </p>
-
- <div id="docs">
- <p>OpenLayers has a very simple XML format class (OpenLayers.Format.XML)
- that can be used to read/write XML docs. The methods available on the
- XML format (or parser if you like) allow for reading and writing of the
- various XML flavors used by the library - in particular the vector data
- formats. It is by no means intended to be a full-fledged XML toolset.
- Additional methods will be added only as needed elsewhere in the
- library.</p>
- <p>This page loads an XML document and demonstrates a few of the methods
- available in the parser.</p>
- <p>Status: <b>XML document <span id="loadStatus">loading..</span>.</b></p>
- <p>After the XML document loads, see the result of a few of the methods
- below. Assume that you start with the following code:
- <br>
- <span class="code">
- var format = new OpenLayers.Format.XML();
- </span>
- </p>
- Sample methods
- <ul>
- <li><a href="javascript:void write();">format.write()</a> - write the XML doc as text</li>
- <li><a href="javascript:void getElementsByTagNameNS(doc, 'http://www.opengis.net/gml', 'MultiPolygon');">format.getElementsByTagNameNS()</a> - get all gml:MultiPolygon</li>
- <li><a href="javascript:void hasAttributeNS(doc.documentElement, 'http://www.w3.org/2001/XMLSchema-instance', 'schemaLocation');">format.hasAttributeNS()</a> - test to see schemaLocation attribute exists in the http://www.w3.org/2001/XMLSchema-instance namespace</li>
- <li><a href="javascript:void getAttributeNodeNS(doc.documentElement, 'http://www.w3.org/2001/XMLSchema-instance', 'schemaLocation');">format.getAttributeNodeNS()</a> - get schemaLocation attribute in the http://www.w3.org/2001/XMLSchema-instance namespace</li>
- <li><a href="javascript:void getAttributeNS(doc.documentElement, 'http://www.w3.org/2001/XMLSchema-instance', 'schemaLocation');">format.getAttributeNS()</a> - get schemaLocation attribute value in the http://www.w3.org/2001/XMLSchema-instance namespace</li>
- <li><a href="javascript:void createElementNS('http://bar.com/foo', 'foo:TestNode');">format.createElementNS()</a> - create a foo:TestNode element (and append it to the doc)</li>
- <li><a href="javascript:void createTextNode('test text ');">format.createTextNode()</a> - create a text node (and append it to the doc)</li>
- </ul>
- Output:
- <div id="output">&nbsp;</div>
- </div>
- </body>
