Annotation of embedaddon/php/ext/simplexml/README, revision 1.1

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