Using the CL_XML_DOCUMENT class for XML

The class described in this chapter is based on the very well known and frequently used iXML library. The integrated XML provides a full spectrum of useful tools and methods to read, parse, and edit the XML format. We will use the following XML file in all examples in this chapter:

<?xml version="1.0" encoding="UTF-8"?>
<AIRLINES>
 <SCARR>
 <CARRID>A2</CARRID>
 <CARRNAME>Antarctica Airlines</CARRNAME>
 <CURRCODE>AQD</CURRCODE>
 <URL>http://antarcticaairlines.aq</URL>
 </SCARR>
</AIRLINES>
