[xml] DTD Handlers

[srivatsan s <srivatsan17 yahoo co in>]

I am trying to use libxml DTD handlers.

I have the following below example

 

 

<!ELEMENT p (#PCDATA | %font; | %phrase; | %special; | %form;)* >

This call back xmlSAX2ElementDecl , takes xmlElementContentPtr

Whose data Structure is

struct _xmlElementContent {

    xmlElementContentType     type; /* PCDATA, ELEMENT, SEQ or OR */

    xmlElementContentOccur    ocur; /* ONCE, OPT, MULT or PLUS */

    const xmlChar             *name;    /* Element name */

    struct _xmlElementContent *c1;  /* first child */

    struct _xmlElementContent *c2;  /* second child */

    struct _xmlElementContent *parent;  /* parent */

    const xmlChar             *prefix;  /* Namespace prefix */

};

 

What are these first child and second child ptrs .

Can anyone explain with the above example .
