#include <stdio.h>

#include <libxml/parser.h>

int main()
{
    const char filename[] = "sample.xml";
    xmlDocPtr doc;
    xmlNodePtr root;

    doc = xmlParseFile(filename);
    if( doc==NULL )
    {
        fprintf(stderr,"Unable to open %s\n",filename);
        exit(1);
    }

    root = xmlDocGetRootElement(doc);
    if( root->children )
        puts("The root node has children!");
    else
        puts("No children are available!");

    xmlFreeDoc(doc);

    return(0);
}

Output

The root node has children!

Notes

* The root->children variable evaluates TRUE when the pointer references data, FALSE when the pointer is NULL.
