Each CFXMLNode contains 3 main pieces of information - the node's type, the data string, and a pointer to an additional data structure. The node's type ID is an enum value of type CFXMLNodeTypeID. The data string is always a CFStringRef; the meaning of the string is dependent on the node's type ID. The format of the additional data is also dependent on the node's type; in general, there is a custom structure for each type that requires additional data. See below for the mapping from type ID to meaning of the data string and structure of the additional data. Note that these structures are versioned, and may change as the parser changes. The current version can always be identified by kCFXMLNodeCurrentVersion; earlier versions can be identified and used by passing earlier values for the version number (although the older structures would have been removed from the header). An CFXMLTree is simply a CFTree whose context data is known to be an CFXMLNodeRef. As such, an CFXMLTree can be used to represent an entire XML document; the CFTree provides the tree structure of the document, while the CFXMLNodes identify and describe the nodes of the tree. An XML document can be parsed to a CFXMLTree, and a CFXMLTree can generate the data for the equivalent XML document - see CFXMLParser.h for more information on parsing XML. */ /* Type codes for the different possible XML nodes; this list may grow.*/ enum { kCFXMLNodeTypeDocument = 1, kCFXMLNodeTypeElement = 2, kCFXMLNodeTypeAttribute = 3, kCFXMLNodeTypeProcessingInstruction = 4, kCFXMLNodeTypeComment = 5, kCFXMLNodeTypeText = 6, kCFXMLNodeTypeCDATASection = 7, kCFXMLNodeTypeDocumentFragment = 8, kCFXMLNodeTypeEntity = 9, kCFXMLNodeTypeEntityReference = 10, kCFXMLNodeTypeDocumentType = 11, kCFXMLNodeTypeWhitespace = 12, kCFXMLNodeTypeNotation = 13, kCFXMLNodeTypeElementTypeDeclaration = 14, kCFXMLNodeTypeAttributeListDeclaration = 15 }; typedef CFIndex CFXMLNodeTypeCode; typedef struct { CFDictionaryRef attributes; CFArrayRef attributeOrder; Boolean isEmpty; char _reserved[3]; } CFXMLElementInfo; typedef struct { CFStringRef dataString; } CFXMLProcessingInstructionInfo; typedef struct { CFURLRef sourceURL; CFStringEncoding encoding; } CFXMLDocumentInfo; typedef struct { CFURLRef systemID; CFStringRef publicID; } CFXMLExternalID; typedef struct { CFXMLExternalID externalID; } CFXMLDocumentTypeInfo; typedef struct { CFXMLExternalID externalID; } CFXMLNotationInfo; typedef struct { /* This is expected to change in future versions */ CFStringRef contentDescription; } CFXMLElementTypeDeclarationInfo; typedef struct { /* This is expected to change in future versions */ CFStringRef attributeName; CFStringRef typeString; CFStringRef defaultString; } CFXMLAttributeDeclarationInfo; typedef struct { CFIndex numberOfAttributes; CFXMLAttributeDeclarationInfo *attributes; } CFXMLAttributeListDeclarationInfo; enum { kCFXMLEntityTypeParameter, /* Implies parsed, internal */ kCFXMLEntityTypeParsedInternal, kCFXMLEntityTypeParsedExternal, kCFXMLEntityTypeUnparsed, kCFXMLEntityTypeCharacter }; typedef CFIndex CFXMLEntityTypeCode; typedef struct { CFXMLEntityTypeCode entityType; CFStringRef replacementText; /* NULL if entityType is external or unparsed */ CFXMLExternalID entityID; /* entityID.systemID will be NULL if entityType is internal */ CFStringRef notationName; /* NULL if entityType is parsed */ } CFXMLEntityInfo; typedef struct { CFXMLEntityTypeCode entityType; } CFXMLEntityReferenceInfo; /* dataTypeCode meaning of dataString format of infoPtr =========== ===================== ================= kCFXMLNodeTypeDocument <currently unused> CFXMLDocumentInfo * kCFXMLNodeTypeElement tag name CFXMLElementInfo * kCFXMLNodeTypeAttribute <currently unused> <currently unused> kCFXMLNodeTypeProcessingInstruction name of the target CFXMLProcessingInstructionInfo * kCFXMLNodeTypeComment text of the comment NULL kCFXMLNodeTypeText the text's contents NULL kCFXMLNodeTypeCDATASection text of the CDATA NULL kCFXMLNodeTypeDocumentFragment <currently unused> <currently unused> kCFXMLNodeTypeEntity name of the entity CFXMLEntityInfo * kCFXMLNodeTypeEntityReference name of the referenced entity CFXMLEntityReferenceInfo * kCFXMLNodeTypeDocumentType name given as top-level element CFXMLDocumentTypeInfo * kCFXMLNodeTypeWhitespace text of the whitespace NULL kCFXMLNodeTypeNotation notation name CFXMLNotationInfo * kCFXMLNodeTypeElementTypeDeclaration tag name CFXMLElementTypeDeclarationInfo * kCFXMLNodeTypeAttributeListDeclaration tag name CFXMLAttributeListDeclarationInfo * */ CF_EXPORT CFTypeID CFXMLNodeGetTypeID(void); /* Creates a new node based on xmlType, dataString, and additionalInfoPtr. version (together with xmlType) determines the expected structure of additionalInfoPtr */ CF_EXPORT CFXMLNodeRef CFXMLNodeCreate(CFAllocatorRef alloc, CFXMLNodeTypeCode xmlType, CFStringRef dataString, const void *additionalInfoPtr, CFIndex version); /* Creates a copy of origNode (which may not be NULL). */ CF_EXPORT CFXMLNodeRef CFXMLNodeCreateCopy(CFAllocatorRef alloc, CFXMLNodeRef origNode); CF_EXPORT CFXMLNodeTypeCode CFXMLNodeGetTypeCode(CFXMLNodeRef node); CF_EXPORT CFStringRef CFXMLNodeGetString(CFXMLNodeRef node); CF_EXPORT const void *CFXMLNodeGetInfoPtr(CFXMLNodeRef node); CF_EXPORT CFIndex CFXMLNodeGetVersion(CFXMLNodeRef node); /* CFXMLTreeRef */ /* Creates a childless, parentless tree from node */ CF_EXPORT CFXMLTreeRef CFXMLTreeCreateWithNode(CFAllocatorRef allocator, CFXMLNodeRef node); /* Extracts and returns the node stored in xmlTree */ CF_EXPORT CFXMLNodeRef CFXMLTreeGetNode(CFXMLTreeRef xmlTree); CF_EXTERN_C_END #endif /* ! __COREFOUNDATION_CFXMLNODE__ */
