togayan 4:7dae52cf560f 16 * This class is a clone of TinyXML's TiXmlHandle class.
togayan 4:7dae52cf560f 17 *
togayan 4:7dae52cf560f 18 *
togayan 4:7dae52cf560f 19 * A SP_XmlHandle is a class that wraps a node pointer with null checks; this is
togayan 4:7dae52cf560f 20 * an incredibly useful thing. Note that SP_XmlHandle is not part of the SPXml
togayan 4:7dae52cf560f 21 * DOM structure. It is a separate utility class.
togayan 4:7dae52cf560f 22 *
togayan 4:7dae52cf560f 23
togayan 4:7dae52cf560f 24 Take an example:
togayan 4:7dae52cf560f 25 @verbatim
togayan 4:7dae52cf560f 26 <Document>
togayan 4:7dae52cf560f 27 <Element attributeA = "valueA">
togayan 4:7dae52cf560f 28 <Child attributeB = "value1" />
togayan 4:7dae52cf560f 29 <Child attributeB = "value2" />
togayan 4:7dae52cf560f 30 </Element>
togayan 4:7dae52cf560f 31 <Document>
togayan 4:7dae52cf560f 32 @endverbatim
togayan 4:7dae52cf560f 33
togayan 4:7dae52cf560f 34 Assuming you want the value of "attributeB" in the 2nd "Child" element, a
togayan 4:7dae52cf560f 35 SP_XmlHandle checks for null pointers so it is perfectly safe and correct to use:
togayan 4:7dae52cf560f 36
togayan 4:7dae52cf560f 37 @verbatim
togayan 4:7dae52cf560f 38 SP_XmlHandle rootHandle( parser.getDocument()->getRootElement() );
togayan 4:7dae52cf560f 39 SP_XmlElementNode * child2 = rootHandle.getChild( "Element" )
togayan 4:7dae52cf560f 40 .getChild( "Child", 1 ).toElement();
togayan 4:7dae52cf560f 41
togayan 4:7dae52cf560f 42 if( child2 ) {
togayan 4:7dae52cf560f 43 // do something
togayan 4:7dae52cf560f 44 }
togayan 4:7dae52cf560f 45 @endverbatim
