Function Documentation

static int checkchar (  int  expect, FILE *  f )  [static]

check if the next char is c and barf if not. return 1 if error.

static void dxml_free_attrib (  dxml_attribute *  a  )  [static]

Free attribute of a XML element.

void dxml_free_xml (  dxml_element *  e  )

free the allocated xml structure

dxml_element* dxml_read_xml (  FILE *  f  )

Read the XML file and load it as the element structure. Returns: NULL on fail. Parameters: f  File pointer to the XML file

static dxml_element* initialize_element (  void   )  [static]

Initializes element for use. allocate, and initialize

static void* mallocwm (  int  l  )  [static]

malloc with an error message on error, exits with 1. Parameters: l  size of memory to allocate

static dxml_attribute* read_attribute (  FILE *  f  )  [static]

read attributes, and end with / (/>) or > and give it back to the caller name="string" -- no space allowed? Returns: NULL if no attribute or error.

static char* read_character_stream (  FILE *  f, const char *  stop_chars )  [static]

read character stream Returns: NULL on error

static dxml_element* read_element (  FILE *  f  )  [static]

Read an element tag start -- end. assume that the pointer is at <tagname att="..."> ^ i.e. "<" is already read. Returns: NULL if error.

static int read_element_start (  FILE *  f  )  [static]

read the start of <. .. part Returns: 0 if it is not a XML normal start tag, that no further processing is required. 1 if it is a normal start tag. 2 on error.

static dxml_element* read_PCDATA (  FILE *  f  )  [static]

reads PCdata, and returns. Returns: NULL on error.

static int skip_read_comment (  FILE *  f  )  [static]

read comment, <!(--) --> Returns: 0 on success, 1 on error

static int skip_read_PI (  FILE *  f, int  strict )  [static]

read PI or doctype decl, <? . .. ?> Returns: 1 on error. Parameters: strict  Check for < ?

static int skipwhitechars (  FILE *  f  )  [static]

skip whitechar characters. .. Returns: 0 on success, 1 on EOF
