Function Documentation

void XLX_character (  void *  data, const char *  element, int  len )

Handles a character element. Parameters: data  Current state of the parser element  Charater element len  Length of the character element

Here is the call graph for this function:

void XLX_character_noop (  XLX_state *  state, const char *  element, int  len )

No-op character element handler. Parameters: state  Pointer to the current state of the parser element  The text string from the current element len  Length of element

void XLX_character_tag (  XLX_state *  state, const char *  element, int  len )

Handles a character element inside a parent tag by delegating the work to the first child. Parameters: state  Current state of the parser element  Charater element len  Length of the character element /para If there are valid characters in the character element then the first child of the current tag is pushed onto the stack and then XLX_character is called to handle the character parsing. After the parsing is complete the child is popped off the stack.

Here is the call graph for this function:

void XLX_end (  void *  data, const char *  element )

Handles an end tag. Parameters: data  Current state of the parser element  Element name from end tag

Here is the call graph for this function:

void XLX_enter_noop (  XLX_state *  state, const char **  attribute )

No-op enter element handler. Parameters: state  Pointer to the current state of the parser attribute  Attribute list for the current element

void XLX_exit_noop (  XLX_state *  state  )

No-op exit element handler. Parameters: state  Pointer to the current state of the parser

void XLX_initState (  XLX_state *  state, unsigned  stackLimit, void *  stackSeed, XLX_pEnter  enter, XLX_pExit  exit, XLX_pCharacter  character, int  verbose )

Initialises the state of the parser. Parameters: state  State to initialise stackLimit  Initial depth of the stack stackSeed  Initial item on the stack enter  Parser default action on encountering an enter tag exit  Parser default action on encountering an exit tag character  Parser default action on encountering a character tag verbose  Vebosity level of the parser, 0 is quiet, non-zero is not

Here is the call graph for this function:

void XLX_printout_down (  XLX_state *  state, const char *  element )

Print an starting tag. Parameters: state  Current state of the parser element  Text string from the current tag

void XLX_printout_up (  XLX_state *  state, const char *  element )

Print an ending tag. Parameters: state  Current state of the parser element  Text string from the current tag

void XLX_start (  void *  data, const char *  element, const char **  attribute )

Handles a start tag. Parameters: data  Current state of the parser element  Element name from start tag attribute  Attribute list from the start tag

Here is the call graph for this function:
