[xml] Parsiing question

["Prashanth R" <ramapra gmail com>]

Hello, 

I am trying to make use of Libxml's sax interfaces . I however ran into a few constraints which I hoped , someone could clear. 

Following are the constraints 

1. I am porting libxml to a target that does not have C filesystem support. 

In other words, I cannot make use of calls such as xmlSAXUserParseFile(FileName) 

Also , I cannot use the same function with the memory option as I do not want to load the entire file in memory. 

The only capablity that my platform has is that of a FileStream object that can do FILE * like operations such as seek , read etc 

2.  I would want to use SAX to parse my xml 

I was looking at the API definition and was wondering if this API 

Function: xmlReadIO

xmlDocPtr	xmlReadIO		(xmlInputReadCallback ioread, 

					 xmlInputCloseCallback ioclose, 
					 void * ioctx, 
					 const char * URL, 
					 const char * encoding, 

int options)

 would work. 

Can this API be used in conjunction with the SAX methodology? In other words, If i am able to supply the callbacks for read and close , will I still be getting SAX callbacks  ( such as StartElement , EndElement etc ). 

I was wondering if someone can help me clarify this and provide an example usage with SAX. 

Your help is really appreciated. 

Thanks
