GET

#define GET   (stack_pos != stack ? *--stack_pos : my_b_get(&cache))

GET_MBCHARLEN

#define GET_MBCHARLEN	(		cs,
			chr,
			len
	)

Value:

  do {                                                  \
    len = my_mbcharlen((cs), (chr));                    \
    if (len == 0 && my_mbmaxlenlen((cs)) == 2) {        \
      const int chr1 = GET;                             \
      if (chr1 != my_b_EOF) {                           \
        len = my_mbcharlen_2((cs), (chr), chr1);        \
        /* Character is gb18030 or invalid (len = 0) */ \
        assert(len == 0 || len == 2 || len == 4);       \
      }                                                 \
      if (len != 0) PUSH(chr1);                         \
    }                                                   \
  } while (0)

The logic here is similar with my_mbcharlen, except for GET and PUSH.

Parameters

[in]	cs	charset info
[in]	chr	the first char of sequence
[out]	len	the length of multi-byte char

PUSH

#define PUSH

(

A

)

*(stack_pos++) = (A)

Function Documentation

my_tospace()

static int my_tospace ( int  chr )

static

Convert newline, linefeed, tab to space.

Parameters

chr

character

According to the "XML 1.0" standard, only space (#x20) characters, carriage returns, line feeds or tabs are considered as spaces. Convert all of them to space (#x20) for parsing simplicity.

my_xml_entity_to_char()

static int my_xml_entity_to_char ( const char *  name, size_t  length  )
