How to get the number of bytes parsed in libxml2

Hi,


I am using the libxml2 sax parser to parse a in memory xml string along with validating it against a schema.


I am using the following code:


xmlSAXHandlerPtr sax_ = new xmlSAXHandler();
sax_->initialized = XML_SAX2_MAGIC;
sax_->startElementNs = this->saxStart;
sax_->endElementNs = this->saxEnd;
sax_->characters = this->saxValue;


xmlParserCtxtPtr inputPtr_ = xmlCreateMemoryParserCtxt(msgBuf,

msgSize);//msgBuf is the in memory xml

//string
ret = xmlSchemaValidateStream(schemaCtxt_, inputPtr_->input->buf,

XML_CHAR_ENCODING_NONE, sax_, this);



I am using

size_t parsedBytes = xmlByteConsumed(inputPtr_);


The validation and parsing is happening just fine but when i get the parsedBytes it always return 0.



Thanks,
Sam Krishna

NAME
libxml - library used to parse XML files DESCRIPTION
The libxml library is used to parse XML files. Its internal document repesentation is as close as possible to the DOM (Document Object Model) interface, an API for accessing XML or HTML structured documents. The libxml library also has a SAX-like interface, which is designed to be compatible with that of another XML parser library called expat. NOTE: SAX, the Simple API for XML, is a standard interface for event-based XML parsing, developed collaboratively by the members of the XML-DEV mailing list, currently hosted by OASIS. The expat library is a XML 1.0 parser written in C, which aims to be fully conforming. It is currently not a validating XML processor. The libxml library now includes a nearly complete XPath implementation. The XPath (XML Path Language) is a language for addressing parts of an XML document, designed to be used by both XSLT and XPointer. The libxml library exports Push and Pull type parser interfaces for both XML and html. FILES
