KCGIXML(3) Library Functions Manual KCGIXML(3)

kcgixmlXML output for kcgi

library “libkcgixml”

Produce output of XML content in a kcgi(3) context allocated with khttp_parse(3).

To compile and link, use pkg-config(1) as follows:

% cc `pkg-config --cflags kcgi-xml` -c sample.c
% cc -o sample sample.o `pkg-config --libs kcgi-xml`

All kcgixml sequences begin with kxml_open(3), emit the standard XML prologue with kxml_prologue(3), create XML nodes, and end with kxml_close(3).

The following outputs a simple XML page. It assumes r is a struct kreq pointer. For brevity, it does not do any error checking.

const char *const elems[] =
  { "foo", "bar", "baz" };
khttp_head(r, kresps[KRESP_STATUS],
  "%s", khttps[KHTTP_200]);
khttp_head(r, kresps[KRESP_CONTENT_TYPE],
  "%s", kmimetypes[KMIME_TEXT_XML]);
khttp_body(r);
kxml_open(&req, r, elems, 3);
kxml_push(&req, 0); /* foo */
kxml_puts(&req, "Hello, world");
kxml_pop(&req);
kxml_pushattrs(&req, 1, "baz", "xyzzy", NULL); /* bar */
kxml_puts(&req, "Hello, world");
kxml_pop(&req);
kxml_close(&req);

kxml_close(3), kxml_open(3), kxml_pop(3), kxml_popall(3), kxml_prologue(3), kxml_push(3), kxml_pushnull(3), kxml_putc(3), kxml_puts(3), kxml_write(3)

The kcgixml functions conform to the XML 1.0 mark-up specification.
