xmlSAXUserParseMemory Problems

I have a project ported from bada that uses xmlSAXUserParseMemory.  It was fine in bada but it is wreaking havoc in my Tizen app.  If I use it too often it eventually crashes my app and using it even once after a call to EvaluateJavascriptN will call all subsequent calls to freeze or crash.  Here is the code:

MethodResult* parse( ByteBuffer* buffer ) 

{

MethodResult* result = new MethodResult();
int ret = xmlSAXUserParseMemory( &(result->saxHandler), result, (char*)buffer->GetPointer(), buffer->GetRemaining() );
xmlCleanupParser();
if ( ret != 0 )
{
 delete result;
 return NULL;
}
return result;
}

Again, this worked fine in bada.

Answered my own question. Apparently there was an error in the XML, however the xmlSAXUserParseMemory function did not return an error. Rather it just leaked memory and caused instability...

Hi Ben I am looking for an example to parse a string using SAXParser. can you give some sample app ? Regards Mohan

Hi Mohan, There is a sample native application "XmlParserApp" that can help you. Or you can go to Help Contents and check 'Libxml2' guide under this: Tizen Native App Programming > Programming Guide > Libraries.

It's possible that the issue you're experiencing with xmlSAXUserParseMemory in your Tizen app is related to differences in how memory is managed between the two platforms.

The issue you're facing with the xmlSAXUserParseMemory function in your Tizen app might be related to compatibility or memory management differences between the bada platform and Tizen Austin photo booth rental. To resolve the problem, you can try the following steps:


Make sure you're using the correct XML parsing functions and libraries for the Tizen platform. Tizen uses the Expat library for XML parsing, so ensure that you have the necessary includes and linked libraries for Expat in your Tizen project.

The xmlSAXUserParseMemory function did not produce an error despite the fact that the Hamilton painters XML contained an error. Rather, it merely produced instability and memory leaks.
