Typedef Documentation

typedef char XML_Char

typedef void(* XML_CharacterDataHandler)(void *userData, const XML_Char *s, int len)

s is not 0 terminated.

typedef void(* XML_CommentHandler)(void *userData, const XML_Char *data)

data is 0 terminated

typedef void(* XML_DefaultHandler)(void *userData, const XML_Char *s, int len)

This is called for any characters in the XML document for which there is no applicable handler. This includes both characters that are part of markup which is of a kind that is not reported (comments, markup declarations), or characters that are part of a construct which could be reported but for which no handler has been supplied. The characters are passed exactly as they were in the XML document except that they will be encoded in UTF-8. Line boundaries are not normalized. Note that a byte order mark character is not passed to the default handler. There are no guarantees about how characters are divided between calls to the default handler: for example, a comment might be split between multiple calls.

typedef void(* XML_EndCdataSectionHandler)(void *userData)

typedef void(* XML_EndDoctypeDeclHandler)(void *userData)

typedef void(* XML_EndElementHandler)(void *userData, const XML_Char *name)

typedef void(* XML_EndNamespaceDeclHandler)(void *userData, const XML_Char *prefix)

typedef int(* XML_ExternalEntityRefHandler)(XML_Parser parser, const XML_Char *context, const XML_Char *base, const XML_Char *systemId, const XML_Char *publicId)

This is called for a reference to an external parsed general entity. The referenced entity is not automatically parsed. The application can parse it immediately or later using XML_ExternalEntityParserCreate. The parser argument is the parser parsing the entity containing the reference; it can be passed as the parser argument to XML_ExternalEntityParserCreate. The systemId argument is the system identifier as specified in the entity declaration; it will not be null. The base argument is the system identifier that should be used as the base for resolving systemId if systemId was relative; this is set by XML_SetBase; it may be null. The publicId argument is the public identifier as specified in the entity declaration, or null if none was specified; the whitespace in the public identifier will have been normalized as required by the XML spec. The context argument specifies the parsing context in the format expected by the context argument to XML_ExternalEntityParserCreate; context is valid only until the handler returns, so if the referenced entity is to be parsed later, it must be copied. The handler should return 0 if processing should not continue because of a fatal error in the handling of the external entity. In this case the calling parser will return an XML_ERROR_EXTERNAL_ENTITY_HANDLING error. Note that unlike other handlers the first argument is the parser, not userData.

typedef void(* XML_ExternalParsedEntityDeclHandler)(void *userData, const XML_Char *entityName, const XML_Char *base, const XML_Char *systemId, const XML_Char *publicId)

typedef void(* XML_InternalParsedEntityDeclHandler)(void *userData, const XML_Char *entityName, const XML_Char *replacementText, int replacementTextLength)

typedef char XML_LChar

typedef void(* XML_NotationDeclHandler)(void *userData, const XML_Char *notationName, const XML_Char *base, const XML_Char *systemId, const XML_Char *publicId)

This is called for a declaration of notation. The base argument is whatever was set by XML_SetBase. The notationName will never be null. The other arguments can be.

typedef int(* XML_NotStandaloneHandler)(void *userData)

This is called if the document is not standalone (it has an external subset or a reference to a parameter entity, but does not have standalone="yes"). If this handler returns 0, then processing will not continue, and the parser will return a XML_ERROR_NOT_STANDALONE error.

typedef void* XML_Parser

typedef void(* XML_ProcessingInstructionHandler)(void *userData, const XML_Char *target, const XML_Char *data)

target and data are 0 terminated

typedef void(* XML_StartCdataSectionHandler)(void *userData)

typedef void(* XML_StartDoctypeDeclHandler)(void *userData, const XML_Char *doctypeName)

This is called for the start of the DOCTYPE declaration when the name of the DOCTYPE is encountered.

typedef void(* XML_StartElementHandler)(void *userData, const XML_Char *name, const XML_Char **atts)

atts is array of name/value pairs, terminated by 0; names and values are 0 terminated.

typedef void(* XML_StartNamespaceDeclHandler)(void *userData, const XML_Char *prefix, const XML_Char *uri)

When namespace processing is enabled, these are called once for each namespace declaration. The call to the start and end element handlers occur between the calls to the start and end namespace declaration handlers. For an xmlns attribute, prefix will be null. For an xmlns="" attribute, uri will be null.

typedef int(* XML_UnknownEncodingHandler)(void *encodingHandlerData, const XML_Char *name, XML_Encoding *info)

This is called for an encoding that is unknown to the parser. The encodingHandlerData argument is that which was passed as the second argument to XML_SetUnknownEncodingHandler. The name argument gives the name of the encoding as specified in the encoding declaration. If the callback can provide information about the encoding, it must fill in the XML_Encoding structure, and return 1. Otherwise it must return 0. If info does not describe a suitable encoding, then the parser will return an XML_UNKNOWN_ENCODING error.

typedef void(* XML_UnparsedEntityDeclHandler)(void *userData, const XML_Char *entityName, const XML_Char *base, const XML_Char *systemId, const XML_Char *publicId, const XML_Char *notationName)

This is called for a declaration of an unparsed (NDATA) entity. The base argument is whatever was set by XML_SetBase. The entityName, systemId and notationName arguments will never be null. The other arguments may be.

Function Documentation

void XMLPARSEAPI XML_DefaultCurrent (  XML_Parser  parser  )

This can be called within a handler for a start element, end element, processing instruction or character data. It causes the corresponding markup to be passed to the default handler.

const XML_LChar XMLPARSEAPI* XML_ErrorString (  int  code  )

Returns a string describing the error.

XML_Parser XMLPARSEAPI XML_ExternalEntityParserCreate (  XML_Parser  parser, const XML_Char *  context, const XML_Char *  encoding )

Creates an XML_Parser object that can parse an external general entity; context is a ''-terminated string specifying the parse context; encoding is a ''-terminated string giving the name of the externally specified encoding, or null if there is no externally specified encoding. The context string consists of a sequence of tokens separated by formfeeds (); a token consisting of a name specifies that the general entity of the name is open; a token of the form prefix=uri specifies the namespace for a particular prefix; a token of the form =uri specifies the default namespace. This can be called at any point after the first call to an ExternalEntityRefHandler so longer as the parser has not yet been freed. The new parser is completely independent and may safely be used in a separate thread. The handlers and userData are initialized from the parser argument. Returns 0 if out of memory. Otherwise returns a new XML_Parser object.

const XML_Char XMLPARSEAPI* XML_GetBase (  XML_Parser  parser  )

void XMLPARSEAPI* XML_GetBuffer (  XML_Parser  parser, int  len )

int XMLPARSEAPI XML_GetCurrentByteCount (  XML_Parser  parser  )

Return the number of bytes in the current event. Returns 0 if the event is in an internal entity.

long XMLPARSEAPI XML_GetCurrentByteIndex (  XML_Parser  parser  )

int XMLPARSEAPI XML_GetCurrentColumnNumber (  XML_Parser  parser  )

int XMLPARSEAPI XML_GetCurrentLineNumber (  XML_Parser  parser  )

These functions return information about the current parse location. They may be called when XML_Parse or XML_ParseBuffer return 0; in this case the location is the location of the character at which the error was detected. They may also be called from any other callback called to report some parse event; in this the location is the location of the first of the sequence of characters that generated the event.

enum XML_Error XMLPARSEAPI XML_GetErrorCode (  XML_Parser  parser  )

If XML_Parse or XML_ParseBuffer have returned 0, then XML_GetErrorCode returns information about the error.

int XMLPARSEAPI XML_GetIdAttributeIndex (  XML_Parser  parser  )

Returns the index of the ID attribute passed in the last call to XML_StartElementHandler, or -1 if there is no ID attribute. Each attribute/value pair counts as 2; thus this correspondds to an index into the atts array passed to the XML_StartElementHandler.

int XMLPARSEAPI XML_GetSpecifiedAttributeCount (  XML_Parser  parser  )

Returns the number of the attribute/value pairs passed in last call to the XML_StartElementHandler that were specified in the start-tag rather than defaulted. Each attribute/value pair counts as 2; thus this correspondds to an index into the atts array passed to the XML_StartElementHandler.

int XMLPARSEAPI XML_Parse (  XML_Parser  parser, const char *  s, int  len, int  isFinal )

Parses some input. Returns 0 if a fatal error is detected. The last call to XML_Parse must have isFinal true; len may be zero for this call (or any other).

int XMLPARSEAPI XML_ParseBuffer (  XML_Parser  parser, int  len, int  isFinal )

XML_Parser XMLPARSEAPI XML_ParserCreate (  const XML_Char *  encoding  )

Constructs a new parser; encoding is the encoding specified by the external protocol or null if there is none specified.

XML_Parser XMLPARSEAPI XML_ParserCreateNS (  const XML_Char *  encoding, XML_Char  namespaceSeparator )

Constructs a new parser and namespace processor. Element type names and attribute names that belong to a namespace will be expanded; unprefixed attribute names are never expanded; unprefixed element type names are expanded only if there is a default namespace. The expanded name is the concatenation of the namespace URI, the namespace separator character, and the local part of the name. If the namespace separator is '' then the namespace URI and the local part will be concatenated without any separator. When a namespace is not declared, the name and prefix will be passed through without expansion.

void XMLPARSEAPI XML_ParserFree (  XML_Parser  parser  )

Frees memory used by the parser.

int XMLPARSEAPI XML_SetBase (  XML_Parser  parser, const XML_Char *  base )

Sets the base to be used for resolving relative URIs in system identifiers in declarations. Resolving relative identifiers is left to the application: this value will be passed through as the base argument to the XML_ExternalEntityRefHandler, XML_NotationDeclHandler and XML_UnparsedEntityDeclHandler. The base argument will be copied. Returns zero if out of memory, non-zero otherwise.

void XMLPARSEAPI XML_SetCdataSectionHandler (  XML_Parser  parser, XML_StartCdataSectionHandler  start, XML_EndCdataSectionHandler  end )

void XMLPARSEAPI XML_SetCharacterDataHandler (  XML_Parser  parser, XML_CharacterDataHandler  handler )

void XMLPARSEAPI XML_SetCommentHandler (  XML_Parser  parser, XML_CommentHandler  handler )

void XMLPARSEAPI XML_SetDefaultHandler (  XML_Parser  parser, XML_DefaultHandler  handler )

This sets the default handler and also inhibits expansion of internal entities. The entity reference will be passed to the default handler.

void XMLPARSEAPI XML_SetDefaultHandlerExpand (  XML_Parser  parser, XML_DefaultHandler  handler )

This sets the default handler but does not inhibit expansion of internal entities. The entity reference will not be passed to the default handler.

void XMLPARSEAPI XML_SetDoctypeDeclHandler (  XML_Parser  parser, XML_StartDoctypeDeclHandler  start, XML_EndDoctypeDeclHandler  end )

void XMLPARSEAPI XML_SetElementHandler (  XML_Parser  parser, XML_StartElementHandler  start, XML_EndElementHandler  end )

int XMLPARSEAPI XML_SetEncoding (  XML_Parser  parser, const XML_Char *  encoding )

This is equivalent to supplying an encoding argument to XML_ParserCreate. It must not be called after XML_Parse or XML_ParseBuffer.

void XMLPARSEAPI XML_SetExternalEntityRefHandler (  XML_Parser  parser, XML_ExternalEntityRefHandler  handler )

void XMLPARSEAPI XML_SetExternalEntityRefHandlerArg (  XML_Parser  , void *  arg )

If a non-null value for arg is specified here, then it will be passed as the first argument to the external entity ref handler instead of the parser object.

void XMLPARSEAPI XML_SetExternalParsedEntityDeclHandler (  XML_Parser  parser, XML_ExternalParsedEntityDeclHandler  handler )

void XMLPARSEAPI XML_SetInternalParsedEntityDeclHandler (  XML_Parser  parser, XML_InternalParsedEntityDeclHandler  handler )

void XMLPARSEAPI XML_SetNamespaceDeclHandler (  XML_Parser  parser, XML_StartNamespaceDeclHandler  start, XML_EndNamespaceDeclHandler  end )

void XMLPARSEAPI XML_SetNotationDeclHandler (  XML_Parser  parser, XML_NotationDeclHandler  handler )

void XMLPARSEAPI XML_SetNotStandaloneHandler (  XML_Parser  parser, XML_NotStandaloneHandler  handler )

int XMLPARSEAPI XML_SetParamEntityParsing (  XML_Parser  parser, enum XML_ParamEntityParsing  parsing )

Controls parsing of parameter entities (including the external DTD subset). If parsing of parameter entities is enabled, then references to external parameter entities (including the external DTD subset) will be passed to the handler set with XML_SetExternalEntityRefHandler. The context passed will be 0. Unlike external general entities, external parameter entities can only be parsed synchronously. If the external parameter entity is to be parsed, it must be parsed during the call to the external entity ref handler: the complete sequence of XML_ExternalEntityParserCreate, XML_Parse/XML_ParseBuffer and XML_ParserFree calls must be made during this call. After XML_ExternalEntityParserCreate has been called to create the parser for the external parameter entity (context must be 0 for this call), it is illegal to make any calls on the old parser until XML_ParserFree has been called on the newly created parser. If the library has been compiled without support for parameter entity parsing (ie without XML_DTD being defined), then XML_SetParamEntityParsing will return 0 if parsing of parameter entities is requested; otherwise it will return non-zero.

void XMLPARSEAPI XML_SetProcessingInstructionHandler (  XML_Parser  parser, XML_ProcessingInstructionHandler  handler )

void XMLPARSEAPI XML_SetUnknownEncodingHandler (  XML_Parser  parser, XML_UnknownEncodingHandler  handler, void *  encodingHandlerData )

void XMLPARSEAPI XML_SetUnparsedEntityDeclHandler (  XML_Parser  parser, XML_UnparsedEntityDeclHandler  handler )

void XMLPARSEAPI XML_SetUserData (  XML_Parser  parser, void *  userData )

This value is passed as the userData argument to callbacks.

void XMLPARSEAPI XML_UseParserAsHandlerArg (  XML_Parser  parser  )

If this function is called, then the parser will be passed as the first argument to callbacks instead of userData. The userData will still be accessible using XML_GetUserData.
