1SimpleXML is meant to be an easy way to access XML data. 2 3SimpleXML objects follow four basic rules: 4 51) properties denote element iterators 62) numeric indices denote elements 73) non numeric indices denote attributes 84) string conversion allows to access TEXT data 9 10When iterating properties then the extension always iterates over 11all nodes with that element name. Thus method children() must be 12called to iterate over subnodes. But also doing the following: 13foreach ($obj->node_name as $elem) { 14 // do something with $elem 15} 16always results in iteration of 'node_name' elements. So no further 17check is needed to distinguish the number of nodes of that type. 18 19When an elements TEXT data is being accessed through a property 20then the result does not include the TEXT data of subelements. 21 22Known issues 23============ 24 25Due to engine problems it is currently not possible to access 26a subelement by index 0: $object->property[0]. 27 28TODO 29==== 30 31At the moment property access to multiple elements of the same 32name returns an array of SimpleXML objects. This should be an 33object of a new type instead so that all kinds of linkage, 34assignment and deleting would work. 35
