[xml] truncated bytes in xml

["Prashant R" <ramapra gmail com>]

Hi , 

I am  using libxml2 in an embedded environment . 

I am trying to use the xmlwriter API's to write xml. 

some of the blocks have a sizeable amount of data ( >1000 bytes ) . 

I am using code similar to this to write each node 

xmlNodePtr pDom ; 

..

...

..

..

xmlTextWriterStartElement(writer,(const xmlChar *)kElem1);

xmlTextWriterWriteString(writer , BAD_CAST GetData() ); // line 2 

xmlTextWriterEndElement(writer);

// 2nd element 

// 3rd element 

xmlTextWriterEndDocument(writer);

xmlFreeTextWriter(writer);

//write out xml to file system 

xmlOutputBufferPtr buffptr= xmlOutputBufferCreateIO (WriteCallbackFunction,CloseCallbackFunction, (void *)&file, NULL);

if(buffptr == NULL)

return false ; 

// Buffer Ptr ,doc , currentnode , level , format , encoding 

xmlNodeDumpOutput(buffptr, pDom->doc, pDom , 0,  0, NULL);

if(xmlOutputBufferClose(buffptr))

return true;

the problem is that  data  is missing in the final xml file. 

Part of the data for Node 1 is written but the rest of the nodes are absent 

something like 

<A><B><Elem1>TUlJRFBEQ0NBaVNnQXdJQkFnSUpBdnNYK3dnSEJBQUNNQTBHQ1NxR1NJYjNEUUVCQlFVQU1I

I have tried replacing the xmlTextWriterWriteString   with other similars API's such as xmlTextWriterWriteRaw and xmlTextWriteWriteBase64 but havent had any success ! 

Is anyone aware of any issues with this or a recommendation for a better way to do this . 

Thanks
