[xml] Parsing multiple documents with SAX - event handlers not triggered for subsequent docs

[Rachael Churchill <rachael churchill linguamatics com>]

Hi

I'm having trouble parsing more than one document with the SAX 
interface. I can parse the first one fine, using xmlParseChunk, and set 
terminate=1 to indicate that this is the final chunk from that document, 
and xmlParseChunk returns success. Then I try to parse a second 
document, and none of the event handlers are triggered for that 
document, but xmlParseChunk still returns success for that document.

Do I need to do something else, as well as setting terminate=1, to 
indicate the end of the first document?

I've reduced the problem to this sample program:

#include "libxml/parser.h"
#include "libxml/HTMLparser.h"
#include "stdlib.h"
#include "string.h"

static xmlSAXHandler SAXHandler;
static xmlParserCtxtPtr XMLParser;

void fnCharacterHandler(void *userData, const xmlChar *s /*not 
null-terminated - use len*/, int len)
{
 printf("character handler\n");
}

int main(void)
{
 char * doc1 = "<Doc>Text 1</Doc>";
 char * doc2 = "<Doc>Text 2</Doc>";
 int ret;

 SAXHandler.characters = fnCharacterHandler;

 XMLParser = xmlCreatePushParserCtxt(&SAXHandler, NULL, NULL, 0, NULL);

 ret = xmlParseChunk(XMLParser, doc1, strlen(doc1), 1 /*terminate*/);
 printf("return value from parsing doc1: %d\n", ret);

 ret = xmlParseChunk(XMLParser, doc2, strlen(doc2), 1 /*terminate*/);
 printf("return value from parsing doc2: %d\n", ret);

 return 0;
}

When I run that I get this output:

character handler
return value from parsing doc1: 0
return value from parsing doc2: 0

but I'd expect to get:

character handler
return value from parsing doc1: 0
character handler
return value from parsing doc2: 0

i.e. I'd expect the character handler to be called when parsing the 
second document too. What do I need to do differently?

Thanks,
Rachael
